By Asaf Kochan, Co-Founder and President, Sentra

Series A announcements are an exciting time for any startup, and we look forward to working with our new investors from Standard Investments, Munich re Ventures (MRV), Moore Strategic Ventures, and INT3 to grow the cloud data security and data security posture management (DSPM) categories. 

I wanted to take a moment to share some of my thoughts around what this round means for Sentra, cloud data security, and the growth of the DSPM category as a whole. 

Seeing is Believing: From Potential Customer to Investor

The most amazing part of this round is that we didn’t originally intend to raise money. We approached Standard Industries as a potential customer not an investor. It was incredible to see how bought-in the team was to Sentra’s approach to data security. They understood instantly the potential for securing not only Standard’s data, but the data of every cloud-first enterprise. The total addressable market for data security solutions is already large, and it’s growing every year, as more and more new companies are now cloud-native. The global need for solutions like Sentra was obvious to their team after seeing the product, and I’m excited to have a forward-thinking investor like Standard as part of our journey. 

It’s a Vote of Confidence in the Sentra Team and Product

Any Series A is first and foremost a vote of confidence. It’s an endorsement of the vision of the company, the approach the product is taking, and the potential of the core team to continue to grow the business. Anyone who has spoken with our talented team understands the level of expertise and perseverance they bring to every task, meeting, and challenge. I’m proud of the team we’ve built, and I’m excited to welcome many new Sentrans to the team in the coming months. 

As I mentioned, the round is also a mark of confidence of the development and direction of the product itself. Working with our existing customers, we’ve regularly added new features, integrations, and capabilities to our solution. As we continue to discover, classify, and secure larger amounts of data in all cloud environments, the benefits of a data centric approach become clear. We’ve successfully reduced the risks of catastrophic data breaches by reducing the data attack surface, improved relationships between engineering and security teams by breaking down silos, and even helped our customers reduce cloud costs by finding and eliminating duplicate data. 

Data Security is a Must, Not a Nice to Have

Raising money in the current economic climate is not to be taken for granted. The significant investment in Sentra’s vision speaks not only to the value provided by Sentra’s product and team, but also to how critical data security has become. Compliance, privacy, and security concerns are present regardless of how the NASDAQ is performing.

Certainly we’re seeing no slowdown in data security regulations. Global enterprises are now responsible for ensuring compliance with a growing number of data regulations from different government and commercial sources across the globe.  When it comes to security and IP protection, the threat of a catastrophic data breach is top of mind for all cloud security teams. As the reality sets in that breaches are not a matter of “if” but “when”, the logic of the data centric approach becomes clear: If you can’t prevent the initial breach, you can make sure your most sensitive data always has the proper security posture. In the future we’re building, not every breach will be newsworthy, because not every breach will involve sensitive data. This funding round demonstrates the growing acceptance that this is the direction cloud security is and should be heading. 

DSPM will Come to Dominate Cloud Security

There’s always some skepticism in the cyber world when a new category is created. 

  • Is the problem it claims to solve really that serious?
  • Can we just use existing paradigms and tools to address it?
  • Is implementing a new tool going to make a real difference for the business? 

These questions are valid, and any cyber company operating in a new space must address them forthrightly and clearly. We have been clear from the beginning - a data centric approach to security with DSPM is not a small step, but a giant leap forward. Data is the core asset of most companies, and that asset is now stored in the cloud. Old approaches will not be sufficient. This new round is led by investors who recognize this new reality and share our vision that we need to put data at the core of cloud security strategies.

I want to end by again emphasizing how thankful I am for having amazing investors, partners, and team members join us over the last 18 months. So much has been accomplished already, but the industry shift to data centric security has only just begun. I’m looking forward to continuing to protect the most important business asset in the world - our data.

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.

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:

  • Automated Data Discovery & Classification: Instantly locate and classify ePHI across cloud and on-prem environments.
  • 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.
