Data Security

As many forward-thinking organizations embrace the transformational potential of innovative cloud architectures- new dimensions of risk are emerging, centered around data privacy, compliance, and the protection of sensitive data. This shift has catapulted cloud data security to the top of the Chief Information Security Officer's (CISO) agenda.

At the Gartner Security and Risk Management summit, Gartner cited some of the pressing priorities for CISOs as safeguarding data across its various forms, adopting a simplified approach, optimizing resource utilization, and achieving low-risk, high-value outcomes. While these may seem like a tall order, they provide a clear roadmap for the future of cloud security.

In light of these priorities, Gartner also highlighted the pivotal trend of integrated security systems. Imagine a holistic ecosystem where proactive and predictive controls harmonize with preventative measures and detection mechanisms. Such an environment empowers security professionals to continuously monitor, assess, detect, and respond to multifaceted risks. This integrated approach catalyzes the move from reaction to anticipation and resolution to prevention.

In this transformative ecosystem, we at Sentra believe that data is the gravitational center of connected cloud security systems and an essential element of the risk equation. Let's unpack this some more.

It's All About the Data.

Given the undeniable impact of major data breaches that have shaken organizations like  Discord, Northern Ireland Police, and Docker Hub, we all know that often the most potent risks lead to sensitive data. 

Security teams have many cloud security tools at their disposal, from Cloud Security Posture Management (CSPM) and Cloud Native Application Protection Platform (CNAPP) to Cloud Access Security Broker (CASB). These are all valuable tools for identifying and prioritizing risks and threats in the cloud infrastructure, network, and applications, but what really matters is the data.  

Let's look at an example of a configuration issue detected in an S3 bucket. The next logical question will be what kind of data resides inside that datastore, how sensitive the data is, and how much of a risk it poses to the organization when aligned with specific security policies that have been set up. These are the critical factors that determine the real risk. Can you imagine assessing risk without understanding the data? Such an assessment would inevitably fall short, lacking the contextual depth necessary to gauge the true extent of risk.

Why is this important? Because sensitive data will raise the severity of the alert. By factoring data sensitivity into risk assessments, prioritizing data-related risks becomes more accurate. This is where Sentra's innovative technology comes into play. By automatically assigning risk scores to the most vital data risks within an organization, Sentra empowers security teams and executives with a comprehensive view of sensitive data at risk. This overview extends the option to delve deep into the root causes of vulnerabilities, even down to the code level.

Prioritized Data Risk Scoring: The Sentra Advantage

Sentra's automated risk scoring is built from a rich data security context. This context originates from a thorough understanding of various layers:

  1. Data Access: Who has access to the data, and how is it governed?
  2. User Activity: What are the users doing with the data? 
  3. Data Movement: How does data move within a complex multi-cloud environment?
  4. Data Sensitivity: How sensitive is the data? 
  5. Misconfigurations: Are there any errors that could expose data?

This creates a holistic picture of data risk, laying a firm and comprehensive foundation for Sentra's unique approach to data risk assessment and prioritized risk scoring. 

Contextualizing Data Risk

Context is everything when it comes to accurate risk prioritization and scoring. Adding the layer of data sensitivity – with its nuanced scoring – further enriches this context, providing a more detailed perspective of the risk landscape. This is the essence of an integrated security system designed to empower security leaders with a clear view of their exposure while offering actionable steps for risk reduction.

The value of this approach becomes evident when security professionals are empowered to manage and monitor risk proactively. The CISO is armed with insights into the organization's vulnerabilities and the means to address them. Data security platforms, such as Sentra's, should seamlessly integrate with the workflows of risk owners. This facilitates timely action, eliminating the need for bottlenecks and unnecessary back-and-forth with security teams.

Moving Forward 

The connection between cloud security and data is profound, shaping the future of cybersecurity practices. A data-centric approach to cloud security will empower organizations to harness the full potential of the cloud while safeguarding the most valuable asset: their data.

Cloud Security 101: Essential Tips and Best Practices

Cloud Security 101: Essential Tips and Best Practices

Cloud security in 2026 is about protecting sensitive data, identities, and workloads across increasingly complex cloud and multi-cloud environments. As organizations continue moving critical systems to the cloud, security challenges have shifted from basic perimeter defenses to visibility gaps, identity risk, misconfigurations, and compliance pressure. Following proven cloud security best practices helps organizations reduce risk, prevent data exposure, and maintain continuous compliance as cloud environments scale and evolve.

Cloud Security 101

At its core, cloud security aims to protect the confidentiality, integrity, and availability of data and services hosted in cloud environments. This requires a clear grasp of the shared responsibility model, where cloud providers secure the underlying physical infrastructure and core services, while customers remain responsible for configuring settings, protecting data and applications, and managing user access.

Understanding how different service models affect your level of control is crucial:

  • Software as a Service (SaaS): Provider manages most security controls; you manage user access and data
  • Platform as a Service (PaaS): Shared responsibility for application security and data protection
  • Infrastructure as a Service (IaaS): You control most security configurations, from OS to applications

Modern cloud security demands cloud-native strategies and automation. Leveraging tools like infrastructure as code, Cloud Security Posture Management (CSPM), and Cloud Workload Protection Platforms helps organizations keep pace with the dynamic, scalable nature of cloud environments. Integrating security into the development process through a "shift left" approach enables teams to detect and remediate vulnerabilities early, before they reach production.

Cloud Security Tips for Beginners

For those new to cloud security, starting with foundational practices builds a strong defense against common threats.

Control Access with Strong Identity Management

  • Use multi-factor authentication on every login to add an extra layer of security
  • Apply the principle of least privilege by granting users and applications only the permissions they need
  • Implement role-based access control across your cloud environment
  • Regularly review and audit identity and access policies

Secure Your Cloud Configurations

Regularly audit your cloud settings and use automated tools like CSPM to continuously scan for misconfigurations and risky exposures. Protecting sensitive data requires encrypting information both at rest and in transit using strong standards such as AES-256, ensuring that even if data is intercepted, it remains unreadable. Follow proper key management practices by regularly rotating keys and avoiding hard-coded credentials.

Monitor and Detect Threats Continuously

  • Consolidate logs from all cloud services into a centralized system
  • Set up real-time monitoring with automated alerts to quickly identify unusual behavior
  • Employ behavioral analytics and threat detection tools to continuously assess your security posture
  • Develop, document, and regularly test an incident response plan

Security Considerations in Cloud Computing

Before adopting or expanding cloud computing, organizations must evaluate several critical security aspects. First, clearly define which security controls fall under the provider's responsibility versus your own. Review contractual commitments, service level agreements, and compliance with data privacy regulations to ensure data sovereignty and legal requirements are met.

Data protection throughout its lifecycle is paramount. Evaluate how data is collected, stored, transmitted, and protected with strong encryption both in transit and at rest. Establish robust identity and access controls, including multi-factor authentication and role-based access - to guard against unauthorized access.

Conducting a thorough pre-migration security assessment is essential:

  • Inventory workloads and classify data sensitivity
  • Map dependencies and simulate attack vectors
  • Deploy CSPM tools to continuously monitor configurations
  • Apply Zero Trust principles—always verify before granting access

Finally, evaluate the provider's internal security measures such as vulnerability management, routine patching, security monitoring, and incident response capabilities. Ensure that both the provider's and your organization's incident response and disaster recovery plans are coordinated, guaranteeing business continuity during security events.

Cloud Security Policies

Organizations should implement a comprehensive set of cloud security policies that cover every stage of data and workload protection.

Policy Type Key Requirements
Data Protection & Encryption Classify data (public, internal, confidential, sensitive) and enforce encryption standards for data at rest and in transit; define key management practices
Access Control & Identity Management Implement role-based access controls, enforce multi-factor authentication, and regularly review permissions to prevent unauthorized access
Incident Response & Reporting Establish formal processes to detect, analyze, contain, and remediate security incidents with clearly defined procedures and communication guidelines
Network Security Define secure architectures including firewalls, VPNs, and native cloud security tools; restrict and monitor network traffic to limit lateral movement
Disaster Recovery & Business Continuity Develop strategies for rapid service restoration including regular backups, clearly defined roles, and continuous testing of recovery plans
Governance, Compliance & Auditing Define program scope, specify roles and responsibilities, and incorporate continuous assessments using CSPM tools to enforce regulatory compliance

Cloud Computing and Cyber Security

Cloud computing fundamentally shifts cybersecurity away from protecting a single, static perimeter toward securing a dynamic, distributed environment. Traditional practices that once focused on on-premises defenses, like firewalls and isolated data centers—must now adapt to an infrastructure where applications and data are continuously deployed and managed across multiple platforms.

Security responsibilities are now shared between cloud providers and client organizations. Providers secure the core physical and virtual components, while clients must focus on configuring services effectively, managing identity and access, and monitoring for vulnerabilities. This dual responsibility model demands clear communication and proactive management to prevent issues like misconfigurations or exposure of sensitive data.

The cloud's inherent flexibility and rapid scaling require automated and adaptive security measures. Traditional manual monitoring can no longer keep pace with the speed at which applications and resources are provisioned or updated. Organizations are increasingly relying on AI-driven monitoring, multi-factor authentication, machine learning, and other advanced techniques to continuously detect and remediate threats in real time.

Cloud environments expand the attack surface by eliminating the traditional network boundary. With data distributed across multiple redundant sites and accessed via numerous APIs, new vulnerabilities emerge that require robust identity- and data-centric protections. Security measures must now encompass everything from strict encryption and access controls to comprehensive logging and incident response strategies that address the unique risks of multi-tenant and distributed architectures.

One Platform to Secure All Data: Moving from Data Discovery to Full Data Access Governance

One Platform to Secure All Data: Moving from Data Discovery to Full Data Access Governance

The cloud has changed how organizations approach data security and compliance. Security leaders have mostly figured out where their sensitive data is, thanks to data security posture management (DSPM) tools. But that's just the beginning. Who can access your data? What are they doing with it?

Workloads and sensitive assets now move across multi-cloud, hybrid, and SaaS environments, increasing the need for control over access and use. Regulators, boards, and customers expect more than just awareness. They want real proof that you are governing access, lowering risk, and keeping cloud data secure. The next priority is here: shifting from just knowing what data you have to actually governing access to it. Sentra provides a unified platform designed for this shift.

Why Discovery Alone Falls Short in the Cloud Era

DSPM solutions make it possible to locate, classify, and monitor sensitive data almost anywhere, from databases to SaaS apps. This visibility is valuable, particularly as organizations manage more data than ever. Over half of enterprises have trouble mapping their full data environment, and 85% experienced a data loss event in the past year.

But simply seeing your data won’t do the job. DSPM can point out risks, like unencrypted data or exposed repositories, but it usually can’t control access or enforce policies in real time. Cloud environments change too quickly for static snapshots and scheduled reviews. Effective security means not only seeing your data but actively controlling who can reach it and what they can do.

Data Access Governance: The New Frontier for Cloud Data Security

Data Access Governance (DAG) covers processes and tools that constantly monitor, control, and audit who can access your data, how, and when, wherever it lives in the cloud.

Why does DAG matter so much now? Consider some urgent needs:

  • Compliance and Auditability: 82% of organizations rank compliance as their top cloud concern. Data access controls and real-time audit logs make it possible to demonstrate compliance with GDPR, HIPAA, and other data laws.
  • Risk Reduction: Cloud environments change constantly, so outdated access policies quickly become a problem. DAG enforces least-privilege access, supports just-in-time permissions, and lets teams quickly respond to risky activity.
  • AI and New Threats: As generative AI becomes more common, concerns about misuse and unsupervised data access are growing. Forty percent of organizations now see AI as a data leak risk.

DAG gives organizations a current view of “who has access to my data right now?” for both employees and AI agents, and allows immediate changes if permissions or risks shift.

The Power of a Unified, Agentless Platform for DSPM and DAG

Why should security teams look for a unified platform instead of another narrow tool? Most large companies use several clouds, with 83% managing more than one, but only 34% have unified compliance. Legacy tools focused on discovery or single clouds aren’t enough.

Sentra’s agentless, multi-cloud solution meets these needs directly. With nothing extra to install or maintain, Sentra provides:

  • Automated discovery and classification of data in AWS, Azure, GCP, and SaaS
  • Real-time mapping and management of every access, from users to services and APIs
  • Policy-as-code for dynamic enforcement of least-privilege access
  • Built-in detection and response that moves beyond basic rules

This approach combines data discovery with ongoing access management, helping organizations save time and money. It bridges the gaps between security, compliance, and DevOps teams. GlobalNewswire projects the global market for unified data governance will exceed $15B by 2032. Companies are looking for platforms that can keep things simple and scale with growth.

Strategic Benefits: From Reduced Risk to Business Enablement

What do organizations actually achieve with cloud-native, end-to-end data access governance?

  • Operational Efficiency: Replace slow, manual reviews and separate tools. Automate access reviews, policy enforcement, and compliance, all in one platform.
  • Faster Remediation and Lower TCO: Real-time alerts pinpoint threats faster, and automation speeds up response and reduces resource needs.
  • Future-Proof Security: Designed to handle multi-cloud and AI demands, with just-in-time access, zero standing privilege, and fast threat response.
  • Business Enablement and Audit Readiness: Central visibility and governance help teams prepare for audits faster, gain customer trust, and safely launch digital products.

In short, a unified platform for DSPM and DAG is more than a tech upgrade, it gives security teams the ability to directly support business growth and agility.

Why Sentra: The Converged Platform for Modern Data Security

Sentra covers every angle: agentless discovery, continuous access control, ongoing threat detection, and compliance, all within one platform. Sentra unites DSPM, DAG, and Data Detection & Response (DDR) in a single solution.

With Sentra, you can:

  • Stop relying on periodic reviews and move to real-time governance
  • See and manage data across all cloud and SaaS services
  • Make compliance easier while improving security and saving money

Conclusion

Data discovery is just the first step to securing cloud data. For compliance, resilience, and agility, organizations need to go beyond simply finding data and actually managing who can use it. DSPM isn’t enough anymore, full Data Access Governance is now a must.

Sentra’s agentless platform gives security and compliance teams a way to find, control, and protect sensitive cloud data, with full oversight along the way. Make the switch now and turn cloud data security into an asset for your business.

Looking to bring all your cloud data security and access control together? Request a Sentra demo to see how it works, or watch a 5-minute product demo for more on how Sentra helps organizations move from discovery to full data governance.

False Positives Are Killing Your DSPM Program: How to Measure Classification Accuracy

False Positives Are Killing Your DSPM Program: How to Measure Classification Accuracy

As more organizations move sensitive data to the cloud, Data Security Posture Management (DSPM) has become a critical security investment. But as DSPM adoption grows, a big problem is emerging: security teams are overwhelmed by false positives that create too much noise and not enough useful insight. If your security program is flooded with unnecessary alerts, you end up with more risk, not less.

Most enterprises say their existing data discovery and classification solutions fall short, primarily because they misclassify data. False positives waste valuable analyst time and deteriorate trust in your security operation. Security leaders need to understand what high-quality data classification accuracy really is, why relying only on regex fails, and how to use objective metrics like precision and recall to assess potential tools. Here’s a look at what matters most for accuracy in DSPM.

What Does Good Data Classification Accuracy Look Like?

To make real progress with data classification accuracy, you first need to know how to measure it. Two key metrics - precision and recall - are at the core of reliable classification. Precision tells you the share of correct positive results among everything identified as positive, while recall shows the percentage of actual sensitive items that get caught. You want both metrics to be high. Your DSPM solution should identify sensitive data, such as PII or PCI, without generating excessive false or misclassified results.

The F1-score adds another perspective, blending precision and recall for a single number that reflects both discovery and accuracy. On the ground, these metrics mean fewer false alerts, quicker responses, and teams that spend their time fixing problems rather than chasing noise. "Good" data classification produces consistent, actionable results, even as your cloud data grows and changes.

The Hidden Cost of Regex-Only Data Discovery

A lot of older DSPM tools still depend on regular expressions (regex) to classify data in both structured and unstructured systems. Regex works for certain fixed patterns, but it struggles with the diverse, changing data types common in today’s cloud and SaaS environments. Regex can't always recognize if a string that “looks” like a personal identifier is actually just a random bit of data. This results in security teams buried by alerts they don’t need, leading to alert fatigue.

Far from helping, regex-heavy approaches waste resources and make it easier for serious risks to slip through. As privacy regulations become more demanding and the average breach hit $4.4 million according to the annual "Cost of a Data Breach Report" by IBM and the Ponemon Institute, ignoring precision and recall is becoming increasingly costly.

How to Objectively Test DSPM Accuracy in Your POC

If your current DSPM produces more noise than value, a better method starts with clear testing. A meaningful proof-of-value (POV) process uses labeled data and a confusion matrix to calculate true positives, false positives, and false negatives. Don’t rely on vendor promises. Always test their claims with data from your real environment. Ask hard questions: How does the platform classify unstructured data? How much alert noise can you expect? Can it keep accuracy high even when scanning huge volumes across SaaS, multi-cloud, and on-prem systems? The best DSPM tool cuts through the clutter, surfacing only what matters.

Sentra Delivers Highest Accuracy with Small Language Models and Context

Sentra’s DSPM platform raises the bar by going beyond regex, using purpose-built small language models (SLMs) and advanced natural language processing (NLP) for context-driven data classification at scale. Customers and analysts consistently report that Sentra achieves over the highest classification accuracy for PII and PCI, with very few false positives.

Gartner Review - Sentra received 5 stars

How does Sentra get these results without data ever leaving your environment? The platform combines multi-cloud discovery, agentless install, and deep contextual awareness - scanning extensive environments and accurately discerning real risks from background noise. Whether working with unstructured cloud data, ever-changing SaaS content, or traditional databases, Sentra keeps analysts focused on real issues and helps you stay compliant. Instead of fighting unnecessary alerts, your team sees clear results and can move faster with confidence.

Reducing False Positives Produces Real Outcomes

Classification accuracy has a direct impact on whether your security is efficient or overwhelmed. With compliance rules tightening and threats growing, security teams cannot afford DSPM solutions that bury them in false positives. Regex-only tools no longer cut it - precision, recall, and truly reliable results should be standard.

Sentra’s SLM-powered, context-aware classification delivers the trustworthy performance businesses need, changing DSPM from just another alert engine to a real tool for reducing risk.
