AI and ML

In today's data-driven world, the success of any data security program hinges on the accuracy, speed, and scalability of its data classification efforts. Why? Because not all data is created equal, and precise data classification lays the essential groundwork for security professionals to understand the context of data-related risks and vulnerabilities. Armed with this knowledge, security operations (SecOps) teams can remediate in a targeted, effective, and prioritized manner, with the ultimate aim of proactively reducing an organization's data attack surface and risk profile over time.

Sentra is excited to introduce Large Language Models (LLMs) into its classification engine. This development empowers enterprises to proactively reduce the data attack surface while accurately identifying and understanding sensitive unstructured data such as employee contracts, source code, and user-generated content at scale.

Many enterprises today grapple with a multitude of data regulations and privacy frameworks while navigating the intricate world of cloud data. Sentra's announcement of adding LLMs to its classification engine is redefining how enterprise security teams understand, manage, and secure their sensitive and proprietary data on a massive scale. Moreover, as enterprises eagerly embrace AI's potential, they must also address unauthorized access or manipulation of Language Model Models (LLMs) and remain vigilant in detecting and responding to security risks associated with AI model training. Sentra is well-equipped to guide enterprises through this multifaceted journey.

A New Era of Data Classification 

Identifying and managing unstructured data has always been a headache for organizations,  whether it's legal documents buried in email attachments, confidential source code scattered across various folders, or user-generated content strewn across collaboration platforms. Imagine a scenario where an enterprise needs to identify all instances of employee contracts within its vast data repositories. Previously, this would have involved painstaking manual searches, leading to inefficiency, potential oversight, and increased security risks.

Sentra’s LMM-powered classification engine can now comprehend the context, sentiment, and nuances of unstructured data, enabling it to classify such data with a level of accuracy and granularity that was previously unimaginable. The model can analyze the content of documents, emails, and other unstructured data sources, not only identifying employee contracts but also providing valuable insights into their context. It can understand contract clauses, expiration dates, and even flag potential compliance issues. Similarly, for source code scattered across diverse folders, Sentra can recognize programming languages, identify proprietary code, and ensure that sensitive code is adequately protected.

When it comes to user-generated content on collaboration platforms, Sentra can analyze and categorize this data, making it easier for organizations to monitor and manage user interactions, ensuring compliance with their policies and regulations. This new classification approach not only aids in understanding the business context of unstructured customer data but also aligns seamlessly with compliance standards such as GDPR, CCPA, and HIPAA. Ensuring the highest level of security, Sentra exclusively scans data with LLM-based classifiers within the enterprise's cloud premises. The assurance that the data never leaves the organization’s environment reduces an additional layer of risk.

Quantifying Risk: Prioritized Data Risk Scores 

Automated data classification capabilities provide a solid foundation for data security management practices. What’s more, data classification speed and accuracy are paramount when striving for an in-depth comprehension of sensitive data and quantifying risk. 

Sentra offers data risk scoring that considers multiple layers of data, including sensitivity scores, access permissions, user activity, data movement, and misconfigurations. This unique technology automatically scores the most critical data risks, providing security teams and executives with a clear, prioritized view of all their sensitive data at-risk, with the option to drill down deeply into the root cause of the vulnerability (often at a code level). 

Having a clear, prioritized view of high-risk data at your fingertips empowers security teams to truly understand, quantify, and prioritize data risks while directing targeted remediation efforts.

The Power of Accuracy and Efficiency

One of the most significant advantages of Sentra's LLM-powered data classification is the unprecedented accuracy it brings to the table. Inaccurate or incomplete data classification can lead to costly consequences, including data breaches, regulatory fines, and reputational damage. With LLMs, Sentra ensures that your data is classified with  precision, reducing the risk of errors and omissions. Moreover, this enhanced accuracy translates into increased efficiency. Sentra's LLM engine can process vast volumes of data in a fraction of the time it would take a human workforce. This not only saves valuable resources but also enables organizations to proactively address security and compliance challenges.

Key developments of Sentra's classification engine encompass:

  • Automatic classification of proprietary customer data with additional context to comply with regulations and privacy frameworks.
  • LLM-powered scanning of data asset content and analysis of metadata, including file names, schemas, and tags.
  • The capability for enterprises to train their LLMs and seamlessly integrate them into Sentra's classification engine for improved proprietary data classification.

Why I Joined Sentra: A Data Defender’s Journey

Why I Joined Sentra: A Data Defender’s Journey

After nearly two decades immersed in cybersecurity, spanning Fortune 500 enterprises, defense contractors, manufacturing giants, consulting, and the vendor ecosystem, I’ve seen firsthand how elusive true data security remains. I've built and led data security programs from scratch in some of the world’s most demanding environments. But when I met the team from Sentra, something clicked in a way that’s rare in this industry.

Let me tell you why I joined Sentra and why I’m more excited than ever about the future of data security.

From Visibility to Vulnerability

In every role I've held, one challenge has consistently stood out: understanding data.
Not just securing it but truly knowing what data we have, where it lives, how it moves, how it's used, and who touches it. This sounds basic, yet it’s one of the least addressed problems in security.

Now, we layer on the proliferation of cloud environments and SaaS sprawl (without mentioning the increasing proliferation of AI agents). The traditional approaches simply don’t cut it. Most organizations either ignore cloud data discovery altogether or lean on point solutions that can’t scale, lack depth, or require endless manual tuning and triage.

That’s exactly where Sentra shines.

Why Sentra?

When I first engaged with Sentra, what struck me was that this wasn’t another vendor trying to slap a new UI on an old problem. Sentra understands the problem deeply and is solving it holistically across all environments. They’re not just keeping up; they’re setting the pace.

The AI-powered data classification engine at the heart of Sentra’s platform is, quite frankly, the best I’ve seen in the market. It automates what previously required a small army of analysts and does so with an accuracy and scale that’s unmatched. It's not just smart, it’s operationally scalable.

But technology alone wasn’t what sold me. It was the people.
The Sentra founders are visionaries who live and breathe this space. They’re not building in a vacuum, they’re listening to customers, responding to real-world friction, and delivering solutions that security teams will actually adopt. That’s rare. That’s powerful.

And finally, there’s the culture. Sentra radiates innovation, agility, and relentless focus on impact. Every person here knows the importance of their role and how it aligns with our mission. That energy is infectious and it’s exactly where I want to be.

Two Decades. One Mission: Secure the Data.

At Sentra, I’m bringing the scars, stories, and successes from almost 20 years “in the trenches”:

  • Deep experience building and maturing data security programs within highly regulated, high-stakes environments

  • A commitment to the full people-process-technology stack, because securing data isn’t just about tools

  • A background stitching together integrated solutions across silos and toolsets

  • A unique perspective shaped by my time as a practitioner, leader, consultant, and vendor

This blend helps me speak the language of security teams, empathize with their challenges, and design strategies that actually work.

Looking Ahead

Joining Sentra isn’t just the next step in my career; it’s a chance to help lead the next chapter of data security. We’re not here to incrementally improve what exists. We’re here to rethink it. Redefine it. Solve it.

If you’re passionate about protecting what matters most, your data. I’d love to connect.

This is more than a job; it’s a mission. And I couldn’t be prouder to be part of it.

What the HIPAA Compliance Updates Mean for Your Security

What the HIPAA Compliance Updates Mean for Your Security

The Health Insurance Portability and Accountability Act (HIPAA) has long been a cornerstone of safeguarding sensitive health information in the U.S., particularly electronic protected health information (ePHI). As healthcare organizations continue to face growing cybersecurity challenges, ensuring the protection of ePHI has never been more critical. 

In response, for the first time in two decades, the U.S. Department of Health and Human Services (HHS) has proposed significant amendments to the HIPAA Security Rule, aimed at strengthening cybersecurity measures across the healthcare sector. These proposed changes are designed to address emerging threats and ensure that healthcare organizations have robust systems in place to protect patient data from unauthorized access and potential breaches. This blog presents the major changes that are coming soon and how you can prepare for them.

Instead of considering compliance as a one-time effort, with Sentra you can monitor your compliance status at any given moment, streamline reporting, and remediate compliance violations instantly.

How Sentra Can Help You Stay Compliant

Sentra’s data security platform equips healthcare organizations with the necessary tools to stay compliant with the new HIPAA Security Rule amendments. By providing continuous monitoring of ePHI data locations and assessing associated risks, Sentra helps organizations maintain full visibility and control over sensitive data.

Key Benefits of Using Sentra for HIPAA Compliance:

  • Real-time Risk Assessment: Continuously assess vulnerabilities and flag security gaps related to HIPAA requirements.
  • Access Control & Encryption Monitoring: Ensure compliance with mandatory MFA, encryption policies, and access termination requirements.
  • Smart Compliance Alerts: Sentra doesn’t just detect generic cloud misconfigurations. Instead, it pinpoints security issues affecting sensitive data, helping teams focus on what truly matters.

Without a solution such as Sentra, organizations waste valuable time manually searching for and classifying sensitive data, diverting key employees from higher-priority security tasks. With Sentra, security teams gain an ongoing, real-time dashboard that ensures efficient compliance and faster risk mitigation.

What You Need to Know About the Proposed HIPAA Security Rule Updates

The latest proposed updates to the HIPAA Security Rule represent some of the most significant changes in years. These updates aim to modernize data protection practices and ensure healthcare organizations are better equipped to handle today’s security challenges. Below are the key highlights compliance and security teams should focus on:

Mandatory Implementation Specifications
All implementation specifications under the HIPAA Security Rule will become mandatory. Covered entities and business associates must now fully comply with all safeguards—no more "addressable" exceptions.

Stricter Encryption Requirements
Encryption of electronic protected health information (ePHI) will be required both at rest and in transit. Organizations must ensure encryption is in place across all systems handling sensitive data.

Required Multifactor Authentication (MFA)
MFA will become mandatory to protect access to ePHI. This added security layer significantly reduces the risk of unauthorized access and credential compromise.

Network Segmentation for Threat Containment
Organizations must implement network segmentation to isolate sensitive systems and limit the spread of cyber threats in the event of a breach.

Timely Termination of Access
Access to ePHI must be revoked within 24 hours when an employee leaves or changes roles. This reduces the risk of insider threats and unauthorized access.

Comprehensive Documentation Requirements
Healthcare organizations must maintain detailed, up-to-date documentation of all security policies, procedures, risk assessments, and incident response plans.

Asset Inventories and Network Mapping
Annual updates to technology asset inventories and network maps will be required to ensure accurate tracking of where and how ePHI is stored and transmitted.

Enhanced Risk Analysis
Organizations must conduct regular, thorough risk assessments to identify vulnerabilities and assess threats across all systems that interact with ePHI.

Stronger Incident Response Plans
Entities must be able to restore lost systems and data within 72 hours after a cyber incident. Regular testing and refinement of incident response protocols will be essential.

Annual Compliance Audits
Healthcare organizations will be required to conduct annual audits of their HIPAA Security Rule compliance, covering all technical and administrative safeguards.

Mandatory Technical Controls
Technical safeguards like anti-malware tools, firewalls, and port restrictions must be in place and regularly reviewed to protect systems from evolving threats.

What’s Next?

The proposed changes to the HIPAA Security Rule are currently in the Notice of Proposed Rulemaking (NPRM) stage, with a 60-day public comment period that opened on January 6, 2025. During this period, stakeholders can provide feedback on the amendments, which may influence the final rule. Organizations should actively monitor the comment period, engage in the feedback process, and stay informed on any potential adjustments before the rule is finalized.

Steps Organizations Should Take Now:

  • Review the proposed changes and understand how they impact your current security posture.
  • Engage in the public comment process to share concerns or recommendations.
  • Start assessing security gaps to align with HIPAA’s evolving compliance requirements.

Conclusion

The new HIPAA compliance amendments represent a major shift in how healthcare organizations must protect electronic Protected Health Information (ePHI). The introduction of enhanced encryption standards, mandatory multi-factor authentication (MFA), and stricter access control measures means organizations must act swiftly to maintain compliance and reduce cybersecurity risks.

Compliance is not just about meeting regulations, it is about efficiency. Organizations relying on manual processes to locate and secure sensitive data waste valuable time and resources, making compliance efforts less effective.

With Sentra, healthcare organizations gain a powerful, automated data security solution that:

  • Eliminates manual data discovery by providing a real-time, continuous inventory of sensitive data.
  • Prioritizes relevant data security risks instead of overwhelming teams with unnecessary alerts.
  • Ensures compliance readiness by automating key processes like access control monitoring and encryption verification.

Now is the time for healthcare organizations to take proactive steps toward compliance. Stay informed, participate in the public comment process, and start implementing security enhancements today.
