Data Security

In the burgeoning realm of artificial intelligence (AI), Large Language Models (LLMs) have emerged as transformative tools, enabling the development of applications that revolutionize customer experiences and streamline business operations. These sophisticated AI models, trained on massive amounts of text data, can generate human-quality text, translate languages, write different kinds of creative content, and answer questions in an informative way.

Unfortunately, the extensive data consumption and rapid adoption of LLMs has also brought to light critical challenges surrounding the protection of data integrity and privacy during the training process. As organizations strive to harness the power of LLMs responsibly, it is imperative to address these vulnerabilities and ensure that sensitive information remains secure.

Challenges: Navigating the Risks of LLM Training

The training of LLMs often involves the utilization of vast amounts of data, often containing sensitive information such as personally identifiable information (PII), intellectual property, and financial records. This wealth of data presents a tempting target for malicious actors seeking to exploit vulnerabilities and gain unauthorized access.

One of the primary challenges is preventing data leakage or public disclosure. LLMs can inadvertently disclose sensitive information if not properly configured or protected. This disclosure can occur through various means, such as unauthorized access to training data, vulnerabilities in the LLM itself, or improper handling of user inputs.

Another critical concern is avoiding overly permissive configurations. LLMs can be configured to allow users to provide inputs that may contain sensitive information. If these inputs are not adequately filtered or sanitized, they can be incorporated into the LLM's training data, potentially leading to the disclosure of sensitive information.

Finally, organizations must be mindful of the potential for bias or error in LLM training data. Biased or erroneous data can lead to biased or erroneous outputs from the LLM, which can have detrimental consequences for individuals and organizations.

OWASP Top 10 for LLM Applications

The OWASP Top 10 for LLM Applications identifies and prioritizes critical vulnerabilities that can arise in LLM applications. Among these, LLM03 Training Data Poisoning, LLM06 Sensitive Information Disclosure, LLM08 Excessive Agency, and LLM10 Model Theft pose significant risks that cybersecurity professionals must address. Let's dive into these:

OWASP Top 10 for LLM Applications

LLM03: Training Data Poisoning

LLM03 addresses the vulnerability of LLMs to training data poisoning, a malicious attack where carefully crafted data is injected into the training dataset to manipulate the model's behavior. This can lead to biased or erroneous outputs, undermining the model's reliability and trustworthiness.

The consequences of LLM03 can be severe. Poisoned models can generate biased or discriminatory content, perpetuating societal prejudices and causing harm to individuals or groups. Moreover, erroneous outputs can lead to flawed decision-making, resulting in financial losses, operational disruptions, or even safety hazards.


LLM06: Sensitive Information Disclosure

LLM06 highlights the vulnerability of LLMs to inadvertently disclosing sensitive information present in their training data. This can occur when the model is prompted to generate text or code that includes personally identifiable information (PII), trade secrets, or other confidential data.

The potential consequences of LLM06 are far-reaching. Data breaches can lead to financial losses, reputational damage, and regulatory penalties. Moreover, the disclosure of sensitive information can have severe implications for individuals, potentially compromising their privacy and security.

LLM08: Excessive Agency

LLM08 focuses on the risk of LLMs exhibiting excessive agency, meaning they may perform actions beyond their intended scope or generate outputs that cause harm or offense. This can manifest in various ways, such as the model generating discriminatory or biased content, engaging in unauthorized financial transactions, or even spreading misinformation.

Excessive agency poses a significant threat to organizations and society as a whole. Supply chain compromises and excessive permissions to AI-powered apps can erode trust, damage reputations, and even lead to legal or regulatory repercussions. Moreover, the spread of harmful or offensive content can have detrimental social impacts.

LLM10: Model Theft

LLM10 highlights the risk of model theft, where an adversary gains unauthorized access to a trained LLM or its underlying intellectual property. This can enable the adversary to replicate the model's capabilities for malicious purposes, such as generating misleading content, impersonating legitimate users, or conducting cyberattacks.

Model theft poses significant threats to organizations. The loss of intellectual property can lead to financial losses and competitive disadvantages. Moreover, stolen models can be used to spread misinformation, manipulate markets, or launch targeted attacks on individuals or organizations.

Recommendations: Adopting Responsible Data Protection Practices

To mitigate the risks associated with LLM training data, organizations must adopt a comprehensive approach to data protection. This approach should encompass data hygiene, policy enforcement, access controls, and continuous monitoring.

Data hygiene is essential for ensuring the integrity and privacy of LLM training data. Organizations should implement stringent data cleaning and sanitization procedures to remove sensitive information and identify potential biases or errors.

Policy enforcement is crucial for establishing clear guidelines for the handling of LLM training data. These policies should outline acceptable data sources, permissible data types, and restrictions on data access and usage.

Access controls should be implemented to restrict access to LLM training data to authorized personnel and identities only, including third party apps that may connect. This can be achieved through role-based access control (RBAC), zero-trust IAM, and multi-factor authentication (MFA) mechanisms.

Continuous monitoring is essential for detecting and responding to potential threats and vulnerabilities. Organizations should implement real-time monitoring tools to identify suspicious activity and take timely action to prevent data breaches.

Solutions: Leveraging Technology to Safeguard Data

In the rush to innovate, developers must remain keenly aware of the inherent risks involved with training LLMs if they wish to deliver responsible, effective AI that does not jeopardize their customer's data.  Specifically, it is a foremost duty to protect the integrity and privacy of LLM training data sets, which often contain sensitive information.

Preventing data leakage or public disclosure, avoiding overly permissive configurations, and negating bias or error that can contaminate such models should be top priorities.

Technological solutions play a pivotal role in safeguarding data integrity and privacy during LLM training. Data security posture management (DSPM) solutions can automate data security processes, enabling organizations to maintain a comprehensive data protection posture.

DSPM solutions provide a range of capabilities, including data discovery, data classification, data access governance (DAG), and data detection and response (DDR). These capabilities help organizations identify sensitive data, enforce access controls, detect data breaches, and respond to security incidents.

Cloud-native DSPM solutions offer enhanced agility and scalability, enabling organizations to adapt to evolving data security needs and protect data across diverse cloud environments.

Sentra: Automating LLM Data Security Processes

Having to worry about securing yet another threat vector should give overburdened security teams pause. But help is available.

Why Sentra Was Named Gartner Peer Insights Customer Choice 2025

Why Sentra Was Named Gartner Peer Insights Customer Choice 2025

When we started Sentra three years ago, we had a hypothesis: organizations were drowning in data they couldn't see, classify, or protect. What we didn't anticipate was how brutally honest our customers would be about what actually works, and what doesn't.

This week, Gartner named Sentra a "Customer's Choice" in their Peer Insights Voice of the Customer report for Data Security Posture Management. The recognition is based on over 650 verified customer reviews, giving us a 4.9/5 rating with 98% willing to recommend us.

The Accuracy Obsession Was Right

The most consistent theme across hundreds of reviews? Accuracy matters more than anything else.

"97.4% of Sentra's alerts in our testing were accurate! By far the highest percentage of any of the DSPM platforms that we tested."

"Sentra accurately identified 99% of PII and PCI in our cloud environments with minimal false positives during the POC."

But customers don't just want data discovery—they want trustworthy data discovery. When your DSPM tool incorrectly flags non-sensitive data as critical, teams waste time investigating false leads. When it misses actual sensitive data, you face compliance gaps and real risk. The reviews validate what we suspected: if security teams can't trust your classifications, the tool becomes shelf-ware. Precision isn't a nice-to-have—it's everything.

How Sentra Delivers Time-to-Value

Another revelation: customers don't just want fast deployment, they want fast insights.

"Within less than a week we were getting results, seeing where our sensitive data had been moved to."

"We were able to start seeing actionable insights within hours."

I used to think "time-to-value" was a marketing term. But when you're a CISO trying to demonstrate ROI to your board, or a compliance officer facing an audit deadline, every day matters. Speed isn’t a luxury in security, it’s a necessity. Data breaches don't wait for your security tools to finish their months-long deployment cycles. Compliance deadlines don't care about your proof-of-concept timeline. Security teams need to move at the speed of business risk.

The Honesty That Stings (And Helps)

But here's what really struck me: our customers were refreshingly honest about our shortcomings.

"The chatbot is more annoying than helpful."

"Currently there is no SaaS support for something like Salesforce."

"It's a startup so it has all the advantages and disadvantages that those come with."

As a founder, reading these critiques was... uncomfortable. But it's also incredibly valuable. Our customers aren't just users, they're partners in our product evolution. They're telling us exactly where to invest our engineering resources.

The Salesforce integration requests, for instance, showed up in nearly every "dislike" section. Message received. We're shipping SaaS connectors specifically because it’s a top priority for our customers.

What Gartner Customer Choice Trends Reveal About the DSPM Market

Analyzing 650 reviews across 9 vendors revealed something fascinating about our market's maturity. Customers aren't just comparing features, they're comparing outcomes.

The traditional data security playbook focused on coverage: "How many data sources can you scan?" But customers are asking different questions:

  • How accurate are your findings?
  • How quickly can I act on your insights?
  • How much manual work does this actually eliminate?

This shift from inputs to outcomes suggests the DSPM market is maturing rapidly. 

The Gartner Voice of the Customer Validated

Perhaps the most meaningful insight came from what customers didn't say. I expected more complaints about deployment complexity, integration challenges, or learning curves. Instead, review after review mentioned how quickly teams became productive with Sentra.

"It was also the fastest set up."

"Quick setup and responsive support."

"The platform is intuitive and offers immediate insights."

This tells me we're solving a real problem in a way that feels natural to security teams. The best products don't just work, they feel inevitable once you use them.

The Road Ahead: Learning from Gartner Choice Recognition

These reviews crystallized our 2025 roadmap priorities:

1. SaaS-First Expansion: Every customer asked for broader SaaS coverage. We're expanding beyond IaaS to support the applications where your most sensitive data actually lives. Our mission is to secure data everywhere.

2. AI Enhancement: Our classification engine is industry-leading, but customers want more. We're building contextual AI that doesn't just find data, it understands data relationships and business impact.

3. Remediation Automation: Customers love our visibility but want more automated remediation. We're moving beyond recommendations to actual risk mitigation.

A Personal Thank You

To the customers who contributed to our Sentra Gartner Peer Insights success: thank you. Building a startup is often a lonely journey of best guesses and gut instincts. Your feedback is the compass that keeps us pointed toward solving real problems.

To the security professionals reading this: your honest feedback (both praise and criticism) makes our products better. If you're using Sentra, please keep telling us what's working and what isn't. If you're not, I'd love to show you what earned us Customer Choice 2025 recognition and why 98% of our customers recommend us.

The data security landscape is evolving rapidly. But with customers as partners and recognition like Gartner Peer Insights Customer Choice 2025, I'm confident we're building tools that don't just keep up with threats, they help organizations stay ahead of them.

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.

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.
