Data Security in 2025: Why DSPM Is Now a Business Imperative

Data Security

At RSAC 2025, I had the opportunity to speak with Adrian Sanabria about one of the most pressing and complex challenges facing security teams today: data security. Since then, the urgency around the future of data security has only intensified.

We're watching a major inflection point unfold across industries. Organizations are generating and storing more data than ever, while simultaneously adopting AI at a pace that outstrips most security programs. At the same time, regulators are enforcing data privacy with increasing sharpness. These trends all converge on one critical question:

 

Do you know where your sensitive data is - and who can access it?

If the answer is no, then it's time to rethink your approach.

Data is Now The Most Valuable, And Volatile Asset

For years, security tools have operated largely without visibility into the data itself. We've focused on endpoints, perimeters, and identities - all essential layers. But in 2025, that’s no longer sufficient.

Data is now the most valuable, and volatile asset most companies have. We’re seeing this in breach investigations, where the root cause often traces back to unmonitored or duplicated sensitive data left in the wrong place. We're seeing it in AI deployments, where teams rush to fine-tune models or deploy copilots without knowing what's inside the datasets they’re exposing. And we’re certainly seeing it in regulatory fines, many of which stem from nothing more than storing customer data longer than necessary, in the wrong place, or in unsecured formats.

What all of this underscores is a simple truth: you can’t protect what you can’t see.

The Role of DSPM in the Future of Data Security

At Sentra, we’ve built our platform around a core philosophy that Data Security Posture Management (DSPM) is not just a security tool, it’s the future of data security, an enabler of responsible innovation. The foundation starts with sensitive data discovery. Most organizations are surprised by how much sensitive data exists outside expected systems- in backups, temporary stores, or SaaS apps that were never properly offboarded. From there, classification adds context. It’s not enough to label something as “PII”, we need to understand how sensitive it is, who owns it, how it is being used, and how it should be governed.

We built Sentra as a cloud-native solution from day one. That means it works across IaaS, SaaS, PaaS, and even on-prem environments without needing agents or pulling data outside the customer’s environment. That last point is non-negotiable for us. As a security company, we believe strongly that extracting customer data for analysis creates unnecessary risk and liability.

To support classification at scale, especially for unstructured data, we developed our own language models using open-source LLMs. This provides the deep contextual understanding needed to accurately label large volumes of data all while maintaining cost efficiency and avoiding unnecessary compute overhead.

AI, Risk, and Responsibility in Data Securityy

One of the biggest shifts we’re seeing in the market is how AI has elevated data security from a technical concern to a boardroom issue. Security teams are now being asked to approve large-scale data usage for AI training, RAG systems, copilots, and internal assistants. But very few have the tools to answer basic questions about what’s in those datasets.

I’ve worked with customers who only realized after deploying AI that they had been exposing medical records, credentials, or confidential meeting data to the model. Once it’s in, you can’t pull it back. That’s why data classification and risk detection must come before any AI integration.

This is precisely the use case we had in mind when we built Sentra’s Data Security for AI Module. It helps teams scan, assess, and verify the contents of data before it ever touches a model. The goal isn’t to slow down innovation - it’s to make it safer, auditable, and repeatable.

Proactive Risk Management Helps Enterprises Ship Faster

One of the most exciting developments we’ve seen for the future of data security is how quickly Sentra’s data security platform becomes a strategic asset for enterprise data risk management. Time to value is fast in many cases, our customers discover major data risks just days after deployment. But beyond those early wins, the real power lies in alignment.

When security leaders can map data to risk, compliance, and governance frameworks, and do so continuously, they’re no longer operating reactively. They’re enabling the business, helping teams ship faster with fewer unknowns, and building trust around how AI and data are managed.

At scale, this kind of maturity is the difference between organizations that can confidently embrace generative AI and those that will always be playing catch-up.

A Final Word

From my time in the Israeli Defense Forces and Unit 8200 to helping enterprises build modern security programs, I’ve seen one truth over and over again: data left behind is data exposed. The volume may grow, the threats may change, but this principle doesn’t.

In 2025, securing data is no longer an aspiration, it’s a baseline. Whether you’re preparing for your next AI initiative, facing regulatory audits, or just trying to get visibility into sprawling cloud environments, DSPM should be your first step. At Sentra, we’re proud to help lead this change. And we believe the organizations that take control of their data today will be the ones best positioned to lead tomorrow.

For four years, he was the commander of Israel’s Unit 8200, leading the world's most innovative cyber team. During those years, he saw threat actors continuously exploit sensitive data that was improperly secured, and worked to mitigate the damage this was causing to both the public and private sectors. Reflecting on these experiences, it was clear to him that sensitive data had become the most important asset in the world. In the private sector, enterprises that were leveraging data to generate new insights, develop new products, and provide better experiences, were separating themselves from the competition. As data becomes more valuable it becomes more of a target. And as the amount of sensitive data grows, so does the importance of finding the most effective way to secure it. That’s why he co-founded Sentra, together with accomplished co-founders Yoav Regev, Ron Reiter, and Yair Cohen.

How to Secure Regulated Data in Microsoft 365 Copilot

How to Secure Regulated Data in Microsoft 365 Copilot

Microsoft 365 Copilot is a game-changer, embedding generative AI directly into your favorite tools like Word, Outlook, and Teams, and giving productivity a huge boost. But for governance, risk, and compliance (GRC) officers and CISOs, this exciting new innovation also brings new questions about governing sensitive data.

So, how can your organization truly harness Copilot safely without risking compliance?

Frameworks like NIST’s AI Risk Management and the EU AI Act offer broad guidance, but they don't prescribe exact controls. At Sentra, we recommend a practical approach: treat Copilot as a sensitive data store capable of serving up data (including highly sensitive, regulated information).

This means applying rigorous data security measures to maintain compliance. Specifically, you'll need to know precisely what data Copilot can access, secure it, clearly map access, and continuously monitor your overall data security posture.

We tackle Copilot security through two critical DSPM concepts: Sanitization and Governance.

1. Sanitization: Minimize Unnecessary Data Exposure

Think of Copilot as an incredibly powerful search engine. It can potentially surface sensitive data hidden across countless repositories. To prevent unintended leaks, your crucial first step is to minimize the amount of sensitive data Copilot can access.

Address Shadow Data and Oversharing

It's common for organizations to have sensitive data lurking in overlooked locations or within overshared files. Copilot's incredible search capabilities can suddenly bring these vulnerabilities to light. Imagine a confidential HR spreadsheet, accidentally shared too broadly, now easily summarized by Copilot for anyone who asks.

The solution? Conduct thorough data housekeeping. This means identifying, archiving, or deleting redundant, outdated, or improperly shared information. Crucially, enforce least privilege access by actively auditing and tightening permissions – ensuring only essential identities have access to sensitive content.

How Sentra Helps

Sentra's DSPM solution leverages advanced AI technologies (like OCR, NER, and embeddings) to automatically discover and classify sensitive data across your entire Microsoft 365 environment. Our intuitive dashboards quickly highlight redundant files, shadow data, and overexposed folders. What's more, we meticulously map access at the identity level, clearly showing which users can access what specific sensitive data – enabling rapid remediation.

For example, in the screenshot below, you'll see a detailed view of an identity (Jacob Simmons) within our system. This includes a concise summary of the sensitive data classes they can access, alongside a complete list of accessible data stores and data assets.

2. Governance: Control AI Output to Prevent Data Leakage

Even after thorough sanitization, some sensitive data must remain accessible within your environment. This is where robust governance comes in, ensuring that Copilot's output never becomes an unintentional vehicle for sensitive data leakage.

Why Output Governance Matters

Without proper controls, Copilot could inadvertently include sensitive details in its generated content or responses. This risk could lead to unauthorized sharing, unchecked sensitive data sprawl, or severe regulatory breaches. The recent EchoLeak vulnerability, for instance, starkly demonstrated how attackers might exploit AI-generated outputs to silently leak critical information.

Leveraging DLP and Sensitivity Labels

Microsoft 365’s Purview Information Protection and DLP policies are powerful tools that allow organizations to control what Copilot can output. Properly labeled sensitive data, such as documents marked “Confidential – Financial,” prompt Copilot to restrict content output, providing users only with references or links rather than sensitive details.

Sentra’s Governance Capabilities

Sentra automatically classifies your data and intelligently applies MPIP sensitivity labels, directly powering Copilot’s critical DLP policies. Our platform integrates seamlessly with Microsoft Purview, ensuring sensitive files are accurately labeled based on flexible, custom business logic. This guarantees that Copilot's outputs remain fully compliant with your active DLP policies.

Below is an example of Sentra’s MPIP label automation in action, showing how we place sensitivity labels on data assets that contain Facebook profile URLs and credit card numbers belonging to EU citizens, which were modified in the past year:

Additionally, our continuous monitoring and real-time alerts empower organizations to immediately address policy violations – for instance, sensitive data with missing or incorrect MPIP labels – helping you maintain audit readiness and seamless compliance alignment.

A Data-Centric Security Approach to AI Adoption

By strategically combining robust sanitization and strong governance, you ensure your regulated data remains secure while enabling safe and compliant Copilot adoption across your organization. This approach aligns directly with the core principles outlined by NIST and the EU AI Act, effectively translating high-level compliance guidance into actionable, practical controls.

At Sentra, our mission is clear: to empower secure AI innovation through comprehensive data visibility and truly automated compliance. Our cutting-edge solutions provide the transparency and granular control you need to confidently embrace Copilot’s powerful capabilities, all without risking costly compliance violations.

Next Steps

Adopting Microsoft 365 Copilot securely doesn’t have to be complicated. By leveraging Sentra’s comprehensive DSPM solutions, your organization can create a secure environment where Copilot can safely enhance productivity without ever exposing your regulated data.

At Black Hat USA 2025, Sentra will demonstrate how security teams can stay ahead of the curve through data-centric strategies that focus on visibility, risk reduction, and real-time response. Join us on August 4-8 at the Mandalay Bay Convention Center in Las Vegas to learn how Sentra’s platform is reshaping the future of cloud data security.

Understanding the Stakes: 2024’s Security Trends

Recent industry data underscores the urgency facing security leaders. Ransomware accounted for 35% of all cyberattacks in 2024 - an 84% increase over the prior year. Misconfigurations continue to be a leading cause of cloud incidents, contributing to nearly a quarter of security events. Phishing remains the most common vector for credential theft, and the use of AI by attackers has moved from experimental to mainstream.

These trends point to a critical shift: attackers are no longer just targeting infrastructure or endpoints. They are going straight for the data.

Why Data-Centric Security Must Be the Focus in 2025

The acceleration of multi-cloud adoption has introduced significant complexity. Sensitive data now resides across AWS, Azure, GCP, and SaaS platforms like Snowflake and Databricks. However, most organizations still struggle with foundational visibility - not knowing where all their sensitive data lives, who has access to it, or how it is being used.

Sentra’s approach to Data Security Posture Management (DSPM) is built to solve this problem. Our platform enables security teams to continuously discover, identify, classify, and secure sensitive data across their cloud environments, and to do so in real time, without agents or manual tagging.
