Data Security

If you had searched for "DSPM" on Google three years ago, you likely would have only found information related to a dspm manufacturing website… But in just a few short years, the concept of Data Security Posture Management (DSPM) has evolved from an idea into a critical component of modern cybersecurity for enterprises.

Let’s rewind to the summer of 2021. Back then, when we were developing what would become Sentra and our DSPM solution, the term didn’t even exist. All that existed was the problem - data was being created, moved and duplicated in the cloud, and its security posture wasn’t keeping pace. Organizations didn’t know where all of their data was, and even if they could find it, its level of protection was inadequate for its level of sensitivity.

After extensive discussions with CISOs and security experts, we realized a critical gap between data security and the modern environments (further exacerbated by the fast pace of AI). Addressing this gap wasn’t just important—it was essential. Through these conversations, we identified the need for a new approach, leading to the creation of the DSPM concept, which didn't exist before. 

It was thrilling to hear my Co-Founder and VP Product, Yair Cohen, declare for the first time, “the world’s first DSPM is coming in 2021.” We embraced the term "Data Security Posture Management," now widely known as "DSPM."

Why DSPM Has Become an Essential Tool

Today, DSPM has become mainstream, helping organizations safeguard their most valuable asset: their data.

"Three years ago, when we founded Sentra, we dreamed of creating a new category called DSPM. It was a huge bet to pursue new budgets, but we believed that data security would be the next big thing due to the shift to the cloud. We could never have imagined that it would become the world’s hottest security category and that the potential would be so significant."

-Ron Reiter, Co-Founder and CTO, Sentra

This summer, Gartner has released its 2024 Hype Cycle for Data Security, and DSPM is in the spotlight for good reason. Gartner describes DSPM as having "transformative" potential, particularly for addressing long-standing data security challenges. As companies rapidly move to the cloud, DSPM solutions are gaining traction by filling critical visibility gaps. The best DSPM solutions offer coverage across multi-cloud and on-premises environments, creating a unified approach to data security. DSPM plays a pivotal role in the modern cybersecurity landscape by providing organizations with real-time visibility into their data security posture. It helps identify, prioritize and mitigate risks across the entire data estate. By continuously monitoring data movement and access patterns, DSPM ensures that any policy violations or deviations from normal behavior are quickly flagged and addressed, preventing potential breaches before they can cause damage.

DSPM is also critical in maintaining compliance with data protection regulations. As organizations handle increasingly complex data environments, meeting regulatory requirements becomes more challenging. DSPM simplifies this process by automating compliance checks and providing clear insights into where sensitive data resides, how it’s being used, and who has access to it. This not only helps organizations avoid hefty fines but also builds trust with customers and stakeholders by demonstrating a commitment to data security and privacy.

In a world where data privacy and security threats rank among the biggest challenges facing society, DSPM provides a crucial layer of protection. Businesses, individuals, and governments are all at risk, with sensitive information constantly under threat. 

That’s why we are committed to developing our data security platform, which ensures your data remains secure and intact, no matter where it travels.

Yoav Regev has over two decades of experience in the world of cybersecurity, cloud, big data, and machine learning. He was the Head of Cyber Department (Colonel) in the Israeli Military Intelligence (Unit 8200) for nearly 25 years. Reflecting on this experience, 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 a bigger 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, Asaf Kochan, 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? What are Microsoft 365 Copilot security best practices?

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.
