How to Choose a Data Access Governance Tool

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.

‍

‍

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.

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

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.
