Data Leakage Detection for AWS Bedrock

When “Enterprise‑Grade” Becomes Too Heavy

BigID helped define the first generation of data discovery and privacy governance platforms. Many large enterprises use it today for PI/PII mapping, RoPA, and DSAR workflows.

‍

But as environments have shifted to multi‑cloud, SaaS, AI, and massive unstructured data, a pattern has emerged in conversations with security leaders and teams:

‍

• Long, complex implementations that depend on professional services
• Scans that are slow or brittle at large scale
• Noisy classification, especially on unstructured data in M365 and file shares
• A UI and reporting model built around privacy/GRC more than day‑to‑day security
• Capacity‑based pricing that’s hard to justify if you don’t fully exploit the platform

Security leaders are increasingly asking:

‍

“If we were buying today, for security‑led DSPM in a cloud‑heavy world, would we choose BigID again, or something built for today’s reality?”

‍

This page gives a straight comparison of BigID vs Sentra through a security‑first lens: time‑to‑value, coverage, classification quality, security use cases, and ROI.

BigID in a Nutshell

Strengths

• Strong privacy, governance, and data intelligence feature set
• Well‑established brand with broad enterprise adoption
• Deep capabilities for DSARs, RoPA, and regulatory mapping

Common challenges security teams report

• Implementation heaviness: significant setup, services, and ongoing tuning
• Performance issues: slow and fragile scans in large or complex estates
• Noise: high false‑positive rates for some unstructured and cloud workloads
• Privacy‑first workflows: harder to operationalize for incident response and DSPM‑driven remediation
• Enterprise‑grade pricing: capacity‑based and often opaque, with costs rising as data and connectors grow

If your primary mandate is privacy and governance, BigID may still be a fit. If your charter is data security; reducing cloud and SaaS risk, supporting AI, and unifying DSPM with detection and access governance, Sentra is built for that outcome.

Sentra in a Nutshell

Sentra is a cloud‑native data security platform that unifies:

‍

• DSPM – continuous data discovery, classification, and posture
• Data Detection & Response (DDR) – data‑aware threat detection and monitoring
• Data Access Governance (DAG) – identity‑to‑data mapping and access control

Key design principles:

‍

• Agentless, in‑environment architecture: connect via cloud/SaaS APIs and lightweight on‑prem scanners so data never leaves your environment.
• Built for cloud, SaaS, and hybrid: consistent coverage across AWS, Azure, GCP, data warehouses/lakes, M365, SaaS apps, and on‑prem file shares & databases.
• High‑fidelity classification: AI‑powered, context‑aware classification tuned for both structured and unstructured data, designed to minimize false positives.
• Security‑first workflows: risk scoring, exposure views, identity‑aware permissions, and data‑aware alerts aligned to SOC, cloud security, and data security teams.

If you’re looking for a BigID alternative that is purpose-built for modern security programs, not just privacy and compliance teams, this is where Sentra pulls ahead as a clear leader.

BigID vs Sentra at a Glance

‍

‍

Time‑to‑Value & Implementation

BigID

• Often treated as a multi‑quarter program, with POCs expanding into large projects.
• Connectors and policies frequently rely on professional services and specialist expertise.
• Day‑2 operations (scan tuning, catalog curation, workflow configuration) can require a dedicated team.

Sentra

• Installs quickly in minutes with an agentless, API‑based deployment model, so teams start seeing classifications and risk insights almost immediately.  
• Provides continuous, autonomous data discovery across IaaS, PaaS, DBaaS, SaaS, and on‑prem data stores, including previously unknown (shadow) data, without custom connectors or heavy reconfiguration. 
• Scans hundreds of petabytes and any size of data store in days while remaining highly compute‑efficient, keeping operational costs low. 
• Ships with robust, enterprise‑ready scan settings and a flexible policy engine, so security and data teams can tune coverage and cadence to their environment without vendor‑led projects. 

If your BigID rollout has stalled or never moved beyond a handful of systems, Sentra’s “install‑in‑minutes, immediate‑value” model is a very different experience.

Coverage: Cloud, SaaS, and On‑Prem

BigID

• Strong visibility across many enterprise data sources, especially structured repositories and data catalogs.
• In practice, customers often cite coverage gaps or operational friction in:
  
  • M365 and collaboration suites
  • Legacy file shares and large unstructured repositories
  • Hybrid/on‑prem environments alongside cloud workloads

Sentra

• Built as a cloud‑native data security platform that covers:
  
  • IaaS/PaaS: AWS, Azure, GCP
  • Data platforms: warehouses, lakes, DBaaS
  • SaaS & collaboration: M365 (SharePoint, OneDrive, Teams, Exchange) and other SaaS
  • On‑prem: major file servers and relational databases via in‑environment scanners
• Designed so that hybrid and multi‑cloud environments are the norm, not an edge case.

If you’re wrestling with a mix of cloud, SaaS, and stubborn on‑prem systems, Sentra’s ability to treat all of that as one data estate is a big advantage.

Classification Quality & Noise

BigID

• Strong foundation for PI/PII discovery and privacy use cases, but security teams often report:
  
  • High volumes of hits that require manual triage
  • Lower precision across certain unstructured or non‑traditional sources
• Over time, this can erode trust because analysts spend more time triaging than remediating.

Sentra

• Uses advanced NLP and model‑driven classification to understand context as well as content.
• Tuned to deliver high precision and recall for both structured and unstructured data, reducing false positives.
• Enriches each finding with rich context e.g.; business purpose, sensitivity, access, residency, security controls, so security teams can make faster decisions.

The result: shorter, more accurate queues of issues, instead of endless spreadsheets of ambiguous hits.

Use Cases: Privacy Catalog vs Security Control Plane

BigID

• Excellent for:
  
  • DSAR handling and privacy workflows
  • RoPA and compliance mapping
  • High‑level data inventories for audit and governance
• For security‑specific use cases (DSPM, incident response, insider risk), teams often end up:
  
  • Exporting BigID findings into SIEM/SOAR or other tools
  • Building custom workflows on top, or supplementing with a separate platform

Sentra

Designed from day one as a data‑centric security control plane, not just a catalog:

• DSPM: continuous mapping of sensitive data, risk scoring, exposure views, and policy enforcement.
• DDR: data‑aware threat detection and activity monitoring across cloud and SaaS.
• DAG: mapping of human and machine identities to data, uncovering over‑privileged access and toxic combinations.
• Integrates with SIEM, SOAR, IAM/CIEM, CNAPP, CSPM, DLP, and ITSM to push data context into the rest of your stack.

Pricing, Economics & ROI

BigID

• Typically capacity‑based and custom‑quoted.
• As you onboard more data sources or increase coverage, licensing can climb quickly.
• When paired with heavier implementation and triage cost, some organizations find it hard to defend renewal spend.

Sentra

• Architecture and algorithms are optimized so the platform can scan very large estates efficiently, which helps control both infrastructure and license costs.
• By unifying DSPM, DDR, and data access governance, Sentra can collapse multiple point tools into one platform.
• Higher classification fidelity and better automation translate into:
  
  • Less analyst time wasted on noise
  • Faster incident containment
  • Smoother, more automated audits

For teams feeling the squeeze of BigID’s TCO, an evaluation with Sentra often shows better security outcomes per dollar, not just a different line item.

When to Choose BigID vs Sentra

BigID may be the better fit if:

• Your primary buyer and owner are privacy, legal, or data governance teams.
• You need a feature‑rich privacy platform first, with security as a secondary concern.
• You’re comfortable with a more complex, services‑led deployment and ongoing management model.

Sentra is likely the better fit if:

• You are a security org leader (CISO, Head of Cloud Security, Director of Data Security).
• Your top problems are cloud, SaaS, AI, and unstructured data risk, not just privacy reporting.
• You want a BigID alternative that:
  
  • Deploys agentlessly in days
  • Handles hybrid/multi‑cloud by design
  • Unifies DSPM, DDR, and access governance into one platform
  • Reduces noise and drives measurable risk reduction

Next Step: Run a Sentra POV Against Your Own Data

The clearest way to compare BigID and Sentra is to see how each performs in your actual environment. Run a focused Sentra POV on a few high‑value domains (e.g., key cloud accounts, M365, a major warehouse) and measure time‑to‑value, coverage, noise, and risk reduction side by side.

Most data loss prevention (DLP) programs don’t fail because DLP tools can’t block an email or stop a file upload. They fail because the DLP strategy and architecture start with enforcement and agents instead of with data intelligence.

‍

If you begin with rules and agents, you’ll usually end up where many enterprises already are:

‍

• A flood of false positives
• Blind spots in cloud and SaaS
• Users who quickly learn how to route around controls
• A DLP deployment that slowly gets dialed down into “monitor‑only” mode

A modern DLP strategy flips this model. It’s built on three tightly integrated components:

‍

1. DSPM (Data Security Posture Management) – the data‑centric brain that discovers and classifies data everywhere, labels it, and orchestrates remediation at the source.
2. Endpoint DLP – the in‑use and egress enforcement layer on laptops and workstations that tracks how sensitive data moves to and from endpoints and actively prevents loss.
3. Network and cloud security (Cloud DLP / SSE/CASB) – the in‑transit control plane that observes and governs how data moves between data stores, across clouds, and between endpoints and the internet.

Get these three components right and make DSPM the intelligence layer feeding the other two and your DLP stops being a noisy checkbox exercise and starts behaving like a real control.

Why Traditional DLP Fails

Traditional DLP started from the edges: install agents, deploy gateways, enable a few content rules, and hope you can tune your way out of the noise. That made sense when most sensitive data was in a few databases and file servers, and most traffic went through a handful of channels.

‍

Today, sensitive data sprawls across:

‍

• Multiple public clouds and regions
• SaaS platforms and collaboration suites
• Data lakes, warehouses, and analytics platforms
• AI models, copilots, and agents consuming that data

Trying to manage DLP purely from traffic in motion is like trying to run identity solely from web server logs. You see fragments of behavior, but you don’t know what the underlying assets are, how risky they are, or who truly needs access.

A modern DLP architecture starts from the data itself.

Component 1 – DSPM: The Brain of Your DLP Strategy

What is DSPM and how does it power modern DLP?

‍

Data Security Posture Management (DSPM) is the foundation of a modern DLP program. Instead of trying to infer everything from traffic, you start by answering four basic questions about your data:

‍

• What data do we have?
• Where does it live (cloud, SaaS, on‑prem, backups, data lakes)?
• Who can access it, and how is it used?
• How sensitive is it, in business and regulatory terms?

A mature DSPM platform gives you more than just a catalog. It delivers:

Comprehensive discovery. It scans across IaaS, PaaS, DBaaS, SaaS, and on‑prem file systems, including “shadow” databases, orphaned snapshots, forgotten file shares, and legacy stores that never made it into your CMDB. You get a real‑time, unified view of your data estate, not just what individual teams remember to register.

‍

Accurate, contextual classification. Instead of relying on regex alone, DSPM combines pattern‑based detection (for PII, PCI, PHI), schema‑aware logic for structured data, and AI/LLM‑driven classification for unstructured content, images, audio, and proprietary data. That means it understands both what the data is and why it matters to the business.

‍

Unified sensitivity labeling. DSPM can automatically apply or update sensitivity labels across systems, for example, Microsoft Purview Information Protection (MPIP) labels in M365, or Google Drive labels, so that downstream DLP controls see a consistent, high‑quality signal instead of a patchwork of manual tags.

‍

Data‑first access context. By building an authorization graph that shows which users, roles, services, and external principals can reach sensitive data across clouds and SaaS, DSPM reveals over‑privileged access and toxic combinations long before an incident.

‍

Policy‑driven remediation at the source. DSPM isn’t just read‑only. It can auto‑revoke public shares, tighten labels, move or delete stale data, and trigger tickets and workflows in ITSM/SOAR systems to systematically reduce risk at rest.

In a DLP plan, DSPM is the intelligence and control layer for data at rest. It discovers, classifies, labels, and remediates issues at the source, then feeds rich context into endpoint DLP agents and network controls.

That’s the role you want DLP to have a brain for and it’s why DSPM should come first.

Component 2 – Endpoint DLP: Data in Use and Leaving the Org

What is Endpoint DLP and why isn’t it enough on its own?

‍

Even with good posture in your data stores, a huge amount of risk is introduced at endpoints when users:

‍

• Copy sensitive data into personal email or messaging apps
• Upload confidential documents to unsanctioned SaaS tools
• Save regulated data to local disks and USB drives
• Take screenshots, copy and paste, or print sensitive content

An Endpoint DLP agent gives you visibility and control over data in use and data leaving the org from user devices.

A well‑designed Endpoint DLP layer should offer:

‍

Rich data lineage. The agent should track how a labeled or classified file moves from trusted data stores (S3, SharePoint, Snowflake, Google Drive, Jira, etc.) to the endpoint, and from there into email, browsers, removable media, local apps, and sync folders. That lineage is essential for both investigation and policy design.

‍

Channel‑aware controls. Endpoints handle many channels: web uploads and downloads, email clients, local file operations, removable media, virtual drives, sync tools like Dropbox and Box. You need policies tailored to these different paths, not a single blunt rule that treats them all the same.

‍

Active prevention and user coaching. Logging is useful, but modern DLP requires the ability to block prohibited transfers (for example, Highly Confidential data to personal webmail), quarantine or encrypt files when risk conditions are met, and present user coaching dialogs that explain why an action is risky and how to do it safely instead.

‍

The most critical design decision is to drive endpoint DLP from DSPM intelligence instead of duplicating classification logic on every laptop. DSPM discovers and labels sensitive content at the data source. When that content is synced or downloaded to an endpoint, files carry their sensitivity labels and metadata with them. The endpoint agent then uses those labels, plus local context like user, device posture, network, and destination, to enforce simple, reliable policies.

That’s far more scalable than asking every agent to rediscover and reclassify all the data it sees.

Component 3 – Network & Cloud Security: Data in Transit

The third leg of a good DLP plan is your network and cloud security layer, typically built from:

• SSE/CASB and secure web gateways controlling access to SaaS apps and web destinations
• Email security and gateways inspecting outbound messages and attachments
• Cloud‑native proxies and API security governing data flows between apps, services, and APIs

Their role in DLP is to observe and govern data in transit:

• Between cloud data stores (e.g., S3 to external SaaS)
• Between clouds (AWS ↔ GCP ↔ Azure)
• Between endpoints and internet destinations (uploads, downloads, webmail, file sharing, genAI tools)

They also enforce inline policies such as:

• Blocking uploads of “Restricted” data to unapproved SaaS
• Stripping or encrypting sensitive attachments
• Requiring step‑up authentication or justification for high‑risk transfers

Again, the key is to feed these controls with DSPM labels and context, not generic heuristics. SSE/CASB and network DLP should treat MPIP or similar labels, along with DSPM metadata (data category, regulation, owner, residency), as primary policy inputs. Email gateways should respect a document already labeled “Highly Confidential – Finance – PCI” as a first‑class signal, rather than trying to re‑guess its contents from scratch. Cloud DLP and Data Detection & Response (DDR) should correlate network events with your data inventory so they can distinguish real exfiltration from legitimate flows.

‍

When network and cloud security speak the same data language as DSPM and endpoint DLP, “data in transit” controls become both more accurate and easier to justify.

How DSPM, Endpoint DLP, and Cloud DLP Work Together

Think of the architecture like this:

‍

• DSPM (Sentra) – “Know and label.” It discovers all data stores (cloud, SaaS, on‑prem), classifies content with high accuracy, applies and manages sensitivity labels, and scores risk at the source.
• Endpoint DLP – “Control data in use.” It reads labels and metadata on files as they reach endpoints, tracks lineage (which labeled data moved where, via which channels), and blocks, encrypts, or coaches when users attempt risky transfers.
• Network / Cloud security – “Control data in transit.” It uses the same labels and DSPM context for inline decisions across web, SaaS, APIs, and email, monitors for suspicious flows and exfil paths, and feeds events into SIEM/SOAR with full data context for rapid response.

Your SOC and IR teams then operate on unified signals, for example:

‍

• A user’s endpoint attempts to upload a file labeled “Restricted – EU PII” to an unsanctioned AI SaaS from an unmanaged network.
• An API integration is continuously syncing highly confidential documents to a third‑party SaaS that sits outside approved data residency.

This is DLP with context, not just strings‑in‑a‑packet. Each component does what it’s best at, and all three are anchored by the same DSPM intelligence.

Designing Real‑World DLP Policies

Once the three components are aligned, you can design professional‑grade, real‑world DLP policies that map directly to business risk, regulation, and AI use cases.

Regulatory protection (PII, PHI, PCI, financial data)

Here, DSPM defines the ground truth. It discovers and classifies all regulated data and tags it with labels like PII – EU, PHI – US, PCI – Global, including residency and business unit.

‍

Endpoint DLP then enforces straightforward behaviors: block copying PII – EU from corporate shares to personal cloud storage or webmail, require encryption when PHI – US is written to removable media, and coach users when they attempt edge‑case actions.

‍

Network and cloud security systems use the same labels to prevent PCI – Global from being sent to domains outside a vetted allow‑list, and to enforce appropriate residency rules in email and SSE based on those tags.

Because everyone is working from the same labeled view of data, you avoid the policy drift and inconsistent exceptions that plague purely pattern‑based DLP.

Insider risk and data exfiltration

DSPM and DDR are responsible for spotting anomalous access to highly sensitive data: sudden spikes in downloads, first‑time access to critical stores, or off‑hours activity that doesn’t match normal behavior.

Endpoint DLP can respond by blocking bulk uploads of Restricted – IP documents to personal cloud or genAI tools, and by triggering just‑in‑time training when a user repeatedly attempts risky actions.

‍

Network security layers alert when large volumes of highly sensitive data flow to unusual SaaS tenants or regions, and can integrate with IAM to automatically revoke or tighten access when exfiltration patterns are detected.

The result is a coherent insider‑risk story: you’re not just counting alerts; you’re reducing the opportunity and impact of insider‑driven data loss.

Secure and responsible AI / Copilots

Modern DLP strategies must account for AI and copilots as first‑class actors.

DSPM’s job is to identify which datasets feed AI models, copilots, and knowledge bases, and to classify and label them according to regulatory and business sensitivity. That includes training sets, feature stores, RAG indexes, and prompt logs.

‍

Endpoint DLP can prevent users from pasting Restricted – Customer Data directly into unmanaged AI assistants. Network and cloud security can use SSE/CASB to control which AI services are allowed to see which labeled data, and apply DLP rules on prompt and response streams so sensitive information is not surfaced to broader audiences than policy allows.

This is where a platform like Sentra’s data security for AI, and its integrations with Microsoft Copilot, Bedrock agents, and similar ecosystems, becomes essential: AI can still move fast on the right data, while DLP ensures it doesn’t leak the wrong data.

A Pragmatic 90‑Day Plan to Stand Up a Modern DLP Program

If you’re rebooting or modernizing DLP, you don’t need a multi‑year overhaul before you see value. Here’s a realistic 90‑day roadmap anchored on the three components.

Days 0–30: Establish the data foundation (DSPM)

In the first month, focus on visibility and clarity:

‍

• Define your top 5–10 protection outcomes (for example, “no EU PII outside approved regions or apps,” “protect IP design docs from external leakage,” “enable safe Copilot usage”).
• Deploy DSPM across your primary cloud, SaaS, and key on‑prem data sources.
• Build an inventory showing where regulated and business‑critical data lives, who can access it, and how exposed it is today (public links, open shares, stale copies, shadow stores).
• Turn on initial sensitivity labeling and tags (MPIP, Google labels, or equivalent) so other controls can start consuming a consistent signal.

Days 30–60: Integrate and calibrate DLP enforcement planes

Next, connect intelligence to enforcement and learn how policies behave:

‍

• Integrate DSPM with endpoint DLP so labels and classifications are visible at the endpoint.
• Integrate DSPM with M365 / Google Workspace DLP, SSE/CASB, and email gateways so network and SaaS enforcement can use the same labels and context.
• Design a small set of policies per plane, aligned to your prioritized outcomes, for example, label‑based blocking on endpoints, upload and sharing rules in SSE, and auto‑revocation of risky SaaS sharing.
• Run these policies in monitor / audit mode first. Measure both false‑positive and false‑negative rates, and iterate on scopes, classifiers, and exceptions with input from business stakeholders.

Days 60–90: Turn on prevention and operationalize

In the final month, begin enforcing and treating DLP as a living system:

‍

• Move the cleanest, most clearly justified policies into enforce mode (blocking, quarantining, or auto‑remediation), starting with the highest‑risk scenarios.
• Formalize ownership across Security, Privacy, IT, and key business units so it’s always clear who tunes what.
• Define runbooks that spell out who does what when a DLP rule fires, and how quickly.
• Track metrics that matter: reduction in over‑exposed sensitive data, time‑to‑remediate, coverage of high‑value data stores, and for AI the number of agents with access to regulated data and their posture over time.
• Use insights from early incidents to tighten IAM and access governance (DAG), improve classification and labels where business reality differs from assumptions, and expand coverage to additional data sources and AI workloads.

By the end of 90 days, you should have a functioning modern DLP architecture: DSPM as the data‑centric brain, endpoint DLP and cloud DLP as coordinated enforcement planes, and a feedback loop that keeps improving posture over time.

Closing Thoughts

A good DLP plan is not just an endpoint agent, not just a network gateway, and not just a cloud discovery tool. It’s the combination of:

‍

• DSPM as the data‑centric brain
• Endpoint DLP as the in‑use enforcement layer
• Network and cloud security as the in‑transit enforcement layer

 - all speaking the same language of labels, classifications, and business context.

That’s the architecture we see working in real, complex environments: use a platform like Sentra to know and label your data accurately at cloud scale, and let your DLP and network controls do what they do best, now with the intelligence they always needed.

‍

For CISOs, the takeaway is simple: treat DSPM as the brain of your modern DLP strategy, and the tools you already own will finally start behaving like the DLP architecture you were promised.

Snowflake has become one of the most widely adopted cloud data platforms, enabling organizations to store, process, and analyze massive volumes of data at scale. As enterprises increasingly rely on Snowflake for mission-critical workloads, including AI and machine learning initiatives, understanding how to secure data in Snowflake has never been more important. With sensitive information ranging from customer PII to financial records residing in cloud environments, implementing a comprehensive security strategy is essential to protect against unauthorized access, data breaches, and compliance violations. This guide explores the practical steps and best practices for securing your Snowflake environment in 2026.

‍

How to Secure Data in Snowflake Server

Securing data in a Snowflake server environment requires a layered, end-to-end approach that addresses every stage of the data lifecycle.

Authentication and Identity Management

The foundation begins with strong authentication. Organizations should enforce multifactor authentication (MFA) for all user accounts and leverage single sign-on (SSO) or federated identity providers to centralize user verification. For programmatic access, key-pair authentication, OAuth, and workload identity federation provide secure alternatives to traditional credentials. Integrating with centralized identity management systems through SCIM ensures that user provisioning remains current and access rights are automatically updated as roles change.

Network Security

Implement network policies that restrict inbound and outbound traffic through IP whitelisting or VPN/VPC configurations to significantly reduce your attack surface. Private connectivity channels should be used for both inbound access and outbound connections to external stages and Snowpipe automation, minimizing exposure to public networks.

Granular Access Controls

Role-based access control (RBAC) should be implemented across all layers, account, database, schema, and table, to ensure users receive only the permissions they require. Column- and row-level security features, including secure views, dynamic data masking, and row access policies, limit exposure of sensitive data within larger datasets. Consider segregating sensitive or region-specific information into dedicated accounts or databases to meet compliance requirements.

Data Classification and Encryption

Snowflake's tagging capabilities enable organizations to mark sensitive data with labels such as "PII" or "confidential," making it easier to identify, audit, and manage. A centralized tag library maintains consistent classification and helps enforce additional security actions such as dynamic masking or targeted auditing. Encryption protects data both at rest and in transit by default, though organizations with stringent security requirements may implement additional application-level encryption or custom key management practices.

Snowflake Security Best Practices

Implementing security best practices in Snowflake requires a comprehensive strategy that spans identity management, network security, encryption, and continuous monitoring.

‍

• Enforce MFA for all accounts and employ federated authentication or SSO where possible
• Implement robust RBAC ensuring both human users and non-human identities have only required privileges
• Rotate credentials regularly for service accounts and API keys, and promptly remove stale or unused accounts
• Define strict network security policies that block access from unauthorized IP addresses
• Use private connectivity options to keep data ingress and egress within controlled channels
• Enable continuous monitoring and auditing to track user activities and detect suspicious behavior early

By adopting a defense-in-depth strategy that combines multiple controls across the network perimeter, user interactions, and data management, organizations create a resilient environment that reduces the risk of breaches.

Secure Data Sharing in Snowflake

Snowflake's Secure Data Sharing capabilities enable organizations to expose carefully controlled subsets of data without moving or copying the underlying information. This architecture is particularly valuable when collaborating with external partners or sharing data across business units while maintaining strict security controls.

How Data Sharing Works

Organizations create a dedicated share using the CREATE SHARE command, including only specifically chosen database objects such as secure views, secure materialized views, or secure tables where sensitive columns can be filtered or masked. The shared objects become read-only in the consumer account, ensuring that data remains unaltered. Data consumers access the live version through metadata pointers, meaning the data stays in the provider's account and isn't duplicated or physically moved.

Security Controls for Shared Data

• Use secure views or apply table policies to filter or mask sensitive information before sharing
• Grant privileges through dedicated database roles only to approved subsets of data
• Implement Snowflake Data Clean Rooms to define allowed operations, ensuring consumers obtain only aggregated or permitted results
• Maintain provider control to revoke access to a share or specific objects at any time

This combination of techniques enables secure collaboration while maintaining complete control over sensitive information.

Enhancing Snowflake Security with Data Security Posture Management

While Snowflake provides robust native security features, organizations managing petabyte-scale environments often require additional visibility and control. Modern Data Security Posture Management (DSPM) platforms like Sentra complement Snowflake's built-in capabilities by discovering and governing sensitive data at petabyte scale inside your own environment, ensuring data never leaves your control.

‍

Key Capabilities: Sentra tracks data movement beyond static location, monitoring when sensitive assets flow between regions, environments, or into AI pipelines. This is particularly valuable in Snowflake environments where data is frequently replicated, transformed, or shared across multiple databases and accounts.

Sentra identifies "toxic combinations" where high-sensitivity data sits behind broad or over-permissioned access controls, helping security teams prioritize remediation efforts. The platform's classification engine distinguishes between mock data and real sensitive data to prevent false positives in development environments, a common challenge when securing large Snowflake deployments with multiple testing and staging environments.

‍

What Users Like:

• Fast and accurate classification capabilities
• Automation and reporting that enhance security posture
• Improved data visibility and audit processes
• Contextual risk insights that prioritize remediation

User Considerations:

• Initial learning curve with the dashboard

User reviews from January 2026 highlight Sentra's effectiveness in real-world deployments, with organizations praising its ability to provide comprehensive visibility and automated governance needed to protect sensitive data at scale. By eliminating shadow and redundant data, Sentra not only secures organizations for the AI era but also typically reduces cloud storage costs by approximately 20%.

Defining a Robust Snowflake Security Policy

A comprehensive Snowflake security policy should address multiple dimensions of data protection, from access controls to compliance requirements.

‍

‍

Regular policy reviews ensure that security standards evolve with changing threats and business requirements. Schedule access reviews to identify and remove excessive privileges or dormant accounts.

Understanding Snowflake Security Certifications

Snowflake holds multiple security certifications that demonstrate its commitment to data protection and compliance with industry standards. Understanding what these certifications mean helps organizations assess whether Snowflake aligns with their security and regulatory requirements.

‍

• SOC 2 Type II: Verifies appropriate controls for security, availability, processing integrity, confidentiality, and privacy
• ISO 27001: Internationally recognized standard for information security management systems
• HIPAA: Compliance for healthcare data with specific technical and administrative controls
• PCI DSS: Standards for payment card information security
• FedRAMP: Authorization for U.S. government agencies
• GDPR: European data protection compliance with data residency controls and processing agreements

‍

While Snowflake maintains these certifications, organizations remain responsible for configuring their Snowflake environments appropriately and implementing their own security controls to achieve full compliance.

‍

As we move through 2026, securing data in Snowflake remains a critical priority for organizations leveraging cloud data platforms for analytics, AI, and business intelligence. By implementing the comprehensive security practices outlined in this guide, from strong authentication and granular access controls to data classification, encryption, and continuous monitoring, organizations can protect their sensitive data while maintaining the performance and flexibility that make Snowflake so valuable. Whether you're implementing native Snowflake security features or enhancing them with complementary DSPM solutions, the key is adopting a layered, defense-in-depth approach that addresses security at every level.
