Data Security

The hardest part about preventing data breaches in healthcare is continuously knowing where your data is, especially protected healthcare information (PHI). Not having a data security platform that improves posture to mitigate risks and monitors your data for threats creates preventable data security and compliance challenges—especially when healthcare data is constantly shared and moved between teams and ecosystem suppliers. This blog will help you navigate these challenges and implement best practices for preventing data breaches in healthcare.

The Importance of Data Security in Healthcare

Healthcare organizations are facing a heightened risk of data breaches, posing a significant threat to trust and reputation. According to a recent study by Cybersecurity Ventures, healthcare is the most targeted industry for cyberattacks, with a projected cost of $25 billion annually by 2024.
 

The reality is that healthcare cyber attacks come at nearly double the cost of data breaches in other industries. Data breaches in the healthcare industry were the costliest at $10.93 million on average, whereas the financial services were at an average of $5.90 million. This discrepancy can be attributed to the expansive attack surface within the healthcare domain, where organizations prioritize operational outcomes over security. The value of Protected Health Information (PHI) data to threat actors and the stringent regulatory landscape further contribute to the higher costs associated with healthcare breaches.

Healthcare data breaches 2009-2023

The advent of cloud-based data sharing, while fostering collaboration, introduces a spectrum of risks. These include the potential for excessive permissions, unauthorized access, and the challenge of accurately classifying the myriad combinations of Protected Health Information (PHI).

Some of the top causes of data breaches in the healthcare sector are misdelivery and privilege misuse. Failure to effectively address these issues elevates the vulnerability to data theft, and emphasizes the critical need for robust security measures. Attacks on healthcare organizations can serve as a means to various ends. Cybercriminals may steal a victim's healthcare information to perpetrate identity fraud, carry out attacks on financial institutions or insurance companies, or pursue other nefarious objectives. As the healthcare industry continues to embrace technological advancements, striking a delicate balance between innovation and security becomes imperative to navigate the evolving landscape of healthcare cybersecurity.

Healthcare Cybersecurity Regulations & Standards

For healthcare organizations, it is especially crucial to protect patient data and follow industry rules. Transitioning to the cloud shouldn't disrupt compliance efforts. But staying on top of strict data privacy regulations adds another layer of complexity to managing healthcare data.

Below are some of the top healthcare cybersecurity regulations relevant to the industry.


Health Insurance Portability and Accountability Act of 1996 (HIPAA)

HIPAA is pivotal in healthcare cybersecurity, mandating compliance for covered entities and business associates. It requires regular risk assessments and adherence to administrative, physical, and technical safeguards for electronic Protected Health Information (ePHI).

HIPAA, at its core, establishes national standards to protect sensitive patient health information from being disclosed without the patient's consent or knowledge. For leaders in healthcare data management, understanding the nuances of HIPAA's Titles and amendments is essential. Particularly relevant are Title II's (HIPAA Administrative Simplification), Privacy Rule, and Security Rule.

HHS 405(d)

HHS 405(d) regulations, under the Cybersecurity Act of 2015, establish voluntary guidelines for healthcare cybersecurity, embodied in the Healthcare Industry Cybersecurity Practices (HICP) framework. This framework covers email, endpoint protection, access management, and more.

Health Information Technology for Economic and Clinical Health (HITECH) Act

The HITECH Act, enacted in 2009, enhances HIPAA requirements, promoting the adoption of healthcare technology and imposing stricter penalties for HIPAA violations. It mandates annual cybersecurity audits and extends HIPAA regulations to business associates.

Payment Card Industry Data Security Standard (PCI DSS)

PCI DSS applies to healthcare organizations processing credit cards, ensuring the protection of cardholder data. Compliance is necessary for handling patient card information.

Quality System Regulation (QSR)

The Quality System Regulation (QSR), enforced by the FDA, focuses on securing medical devices, requiring measures like access prevention, risk management, and firmware updates. Proposed changes aim to align QSR with ISO 13485 standards.

Health Information Trust Alliance (HITRUST)

HITRUST, a global cybersecurity framework, aids healthcare organizations in aligning with HIPAA guidelines, offering guidance on various aspects including endpoint security, risk management, and physical security. Though not mandatory, HITRUST serves as a valuable resource for bolstering compliance efforts.

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.
