AI and ML

Artificial intelligence (AI) is transforming industries, empowering companies to achieve greater efficiency, and maintain a competitive edge. But here’s the catch: although AI unlocks unprecedented opportunities, its rapid adoption also introduces complex challenges—especially for data security and privacy. 

How do you accelerate transformation without compromising the integrity of your data? How do you harness AI’s power without it becoming a threat?

For security leaders, AI presents this very paradox. It is a powerful tool for mitigating risk through better detection of sensitive data, more accurate classification, and real-time response. However, it also introduces complex new risks, including expanded attack surfaces, sophisticated threat vectors, and compliance challenges.

As AI becomes ubiquitous and enterprise data systems become increasingly distributed, organizations must navigate the complexities of the big-data AI era to scale AI adoption safely. 

In this article, we explore the emerging challenges of using AI in data security and offer practical strategies to help organizations secure sensitive data.

The Emerging Challenges for Data Security with AI

AI-driven systems are driven by vast amounts of data, but this reliance introduces significant security risks—both from internal AI usage and external client-side AI applications. As organizations integrate AI deeper into their operations, security leaders must recognize and mitigate the growing vulnerabilities that come with it.

Below, we outline the four biggest AI security challenges that will shape how you protect data and how you can address them.

1. Expanded Attack Surfaces

AI’s dependence on massive datasets—often unstructured and spread across cloud environments—creates an expansive attack surface. This data sprawl increases exposure to adversarial threats, such as model inversion attacks, where bad actors can reverse-engineer AI models to extract sensitive attributes or even re-identify anonymized data.

To put this in perspective, an AI system trained on healthcare data could inadvertently leak protected health information (PHI) if improperly secured. As adversaries refine their techniques, protecting AI models from data leakage must be a top priority.

For a detailed analysis of this challenge, refer to NIST’s report,Adversarial Machine Learning: A Taxonomy and Terminology of Attacks and Mitigations.

2. Sophisticated and Evolving Threat Landscape

The same AI advancements that enable organizations to improve detection and response are also empowering threat actors. Attackers are leveraging AI to automate and enhance malicious campaigns, from highly targeted phishing attacks to AI-generated malware and deepfake fraud.

According to StrongDM's “The State of AI in Cybersecurity Report,” 65% of security professionals believe their organizations are unprepared for AI-driven threats. This highlights a critical gap: while AI-powered defenses continue to improve, attackers are innovating just as fast—if not faster. Organizations must adopt AI-driven security tools and proactive defense strategies to keep pace with this rapidly evolving threat landscape.

3. Data Privacy and Compliance Risks

AI’s reliance on large datasets introduces compliance risks for organizations bound by regulations such as GDPR, CCPA, or HIPAA. Improper handling of sensitive data within AI models can lead to regulatory violations, fines, and reputational damage. One of the biggest challenges is AI’s opacity—in many cases, organizations lack full visibility into how AI systems process, store, and generate insights from data. This makes it difficult to prove compliance, implement effective governance, or ensure that AI applications don’t inadvertently expose personally identifiable information (PII). As regulatory scrutiny on AI increases, businesses must prioritize AI-specific security policies and governance frameworks to mitigate legal and compliance risks.

4. Risk of Unintentional Data Exposure

Even without malicious intent, generative AI models can unintentionally leak sensitive or proprietary data. For instance, employees using AI tools may unknowingly input confidential information into public models, which could then become part of the model’s training data and later be disclosed through the model’s outputs. Generative AI models—especially large language models (LLMs)—are particularly susceptible to data extrapolation attacks, where adversaries manipulate prompts to extract hidden information.

Techniques like “divergence attacks” on ChatGPT can expose training data, including sensitive enterprise knowledge or personally identifiable information. The risks are real, and the pace of AI adoption makes data security awareness across the organization more critical than ever.

For further insights, explore our analysis of “Emerging Data Security Challenges in the LLM Era.”

Top 5 Strategies for Securing Your Data with AI

To integrate AI responsibly into your security posture, companies today need a proactive approach is essential. Below we outline five key strategies to maximize AI’s benefits while mitigating the risks posed by evolving threats. When implemented holistically, these strategies will empower you to leverage AI’s full potential while keeping your data secure.

1. Data Minimization, Masking, and Encryption

The most effective way to reduce risk exposure is by minimizing sensitive data usage whenever possible. Avoid storing or processing sensitive data unless absolutely necessary. Instead, use techniques like synthetic data generation and anonymization to replace sensitive values during AI training and analysis.

When sensitive data must be retained, data masking techniques—such as name substitution or data shuffling—help protect confidentiality while preserving data utility. However, if data must remain intact, end-to-end encryption is critical. Encrypt data both in transit and at rest, especially in cloud or third-party environments, to prevent unauthorized access.

2. Data Governance and Compliance with AI-SPM

Governance and compliance frameworks must evolve to account for AI-driven data processing. AI Security Posture Management (AI-SPM) tools help automate compliance monitoring and enforce governance policies across hybrid and cloud environments. 

AI-SPM tools enable:

  • Automated data lineage mapping to track how sensitive data flows through AI systems.
  • Proactive compliance monitoring to flag data access violations and regulatory risks before they become liabilities.

By integrating AI-SPM into your security program, you ensure that AI-powered workflows remain compliant, transparent, and properly governed throughout their lifecycle.

3. Secure Use of AI Cloud Tools

AI cloud tools accelerate AI adoption, but they also introduce unique security risks. Whether you’re developing custom models or leveraging pre-trained APIs, choosing trusted providers like Amazon Bedrock or Google’s Vertex AI ensures built-in security protections. 

However, third-party security is not a substitute for internal controls. To safeguard sensitive workloads, your organization should:

  • Implement strict encryption policies for all AI cloud interactions.
  • Enforce data isolation to prevent unauthorized access.
  • Regularly review vendor agreements and security guarantees to ensure compliance with internal policies.

Cloud AI tools can enhance your security posture, but always review the guarantees of your AI providers (e.g., OpenAI's security and privacy page) and regularly review vendor agreements to ensure alignment with your company’s security policies.

4. Risk Assessments and Red Team Testing

While offline assessments provide an initial security check, AI models behave differently in live environments—introducing unpredictable risks. Continuous risk assessments are critical for detecting vulnerabilities, including adversarial threats and data leakage risks.

Additionally, red team exercises simulate real-world AI attacks before threat actors can exploit weaknesses. A proactive testing cycle ensures AI models remain resilient against emerging threats.

To maintain AI security over time, adopt a continuous feedback loop—incorporating lessons learned from each assessment to strengthen your AI systems

5. Organization-Wide AI Usage Guidelines

AI security isn’t just a technical challenge—it’s an organizational imperative. To democratize AI security, companies must embed AI risk awareness across all teams.

  • Establish clear AI usage policies based on zero trust and least privilege principles.
  • Define strict guidelines for data sharing with AI platforms to prevent shadow AI risks.
  • Integrate AI security into broader cybersecurity training to educate employees on emerging AI threats.

By fostering a security-first culture, organizations can mitigate AI risks at scale and ensure that security teams, developers, and business leaders align on responsible AI practices.

Key Takeaways: Moving Towards Proactive AI Security 

AI is transforming how we manage and protect data, but it also introduces new risks that demand ongoing vigilance. By taking a proactive, security-first approach, you can stay ahead of AI-driven threats and build a resilient, future-ready AI security framework.

AI integration is no longer optional for modern enterprises—it is both inevitable and transformative. While AI offers immense potential, particularly in security applications, it also introduces significant risks, especially around data security. Organizations that fail to address these challenges proactively risk increased exposure to evolving threats, compliance failures, and operational disruptions.

By implementing strategies such as data minimization, strong governance, and secure AI adoption, organizations can mitigate these risks while leveraging AI’s full potential. A proactive security approach ensures that AI enhances—not compromises—your overall cybersecurity posture. As AI-driven threats evolve, investing in comprehensive, AI-aware security measures is not just a best practice but a competitive necessity. Sentra’s Data Security Platform provides the necessary visibility and control, integrating advanced AI security capabilities to protect sensitive data across distributed environments.

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.
