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.

How to Secure Regulated Data in Microsoft 365 Copilot

How to Secure Regulated Data in Microsoft 365 Copilot

Microsoft 365 Copilot is a game-changer, embedding generative AI directly into your favorite tools like Word, Outlook, and Teams, and giving productivity a huge boost. But for governance, risk, and compliance (GRC) officers and CISOs, this exciting new innovation also brings new questions about governing sensitive data.

So, how can your organization truly harness Copilot safely without risking compliance?

Frameworks like NIST’s AI Risk Management and the EU AI Act offer broad guidance, but they don't prescribe exact controls. At Sentra, we recommend a practical approach: treat Copilot as a sensitive data store capable of serving up data (including highly sensitive, regulated information).

This means applying rigorous data security measures to maintain compliance. Specifically, you'll need to know precisely what data Copilot can access, secure it, clearly map access, and continuously monitor your overall data security posture.

We tackle Copilot security through two critical DSPM concepts: Sanitization and Governance.

1. Sanitization: Minimize Unnecessary Data Exposure

Think of Copilot as an incredibly powerful search engine. It can potentially surface sensitive data hidden across countless repositories. To prevent unintended leaks, your crucial first step is to minimize the amount of sensitive data Copilot can access.

Address Shadow Data and Oversharing

It's common for organizations to have sensitive data lurking in overlooked locations or within overshared files. Copilot's incredible search capabilities can suddenly bring these vulnerabilities to light. Imagine a confidential HR spreadsheet, accidentally shared too broadly, now easily summarized by Copilot for anyone who asks.

The solution? Conduct thorough data housekeeping. This means identifying, archiving, or deleting redundant, outdated, or improperly shared information. Crucially, enforce least privilege access by actively auditing and tightening permissions – ensuring only essential identities have access to sensitive content.

How Sentra Helps

Sentra's DSPM solution leverages advanced AI technologies (like OCR, NER, and embeddings) to automatically discover and classify sensitive data across your entire Microsoft 365 environment. Our intuitive dashboards quickly highlight redundant files, shadow data, and overexposed folders. What's more, we meticulously map access at the identity level, clearly showing which users can access what specific sensitive data – enabling rapid remediation.

For example, in the screenshot below, you'll see a detailed view of an identity (Jacob Simmons) within our system. This includes a concise summary of the sensitive data classes they can access, alongside a complete list of accessible data stores and data assets.

2. Governance: Control AI Output to Prevent Data Leakage

Even after thorough sanitization, some sensitive data must remain accessible within your environment. This is where robust governance comes in, ensuring that Copilot's output never becomes an unintentional vehicle for sensitive data leakage.

Why Output Governance Matters

Without proper controls, Copilot could inadvertently include sensitive details in its generated content or responses. This risk could lead to unauthorized sharing, unchecked sensitive data sprawl, or severe regulatory breaches. The recent EchoLeak vulnerability, for instance, starkly demonstrated how attackers might exploit AI-generated outputs to silently leak critical information.

Leveraging DLP and Sensitivity Labels

Microsoft 365’s Purview Information Protection and DLP policies are powerful tools that allow organizations to control what Copilot can output. Properly labeled sensitive data, such as documents marked “Confidential – Financial,” prompt Copilot to restrict content output, providing users only with references or links rather than sensitive details.

Sentra’s Governance Capabilities

Sentra automatically classifies your data and intelligently applies MPIP sensitivity labels, directly powering Copilot’s critical DLP policies. Our platform integrates seamlessly with Microsoft Purview, ensuring sensitive files are accurately labeled based on flexible, custom business logic. This guarantees that Copilot's outputs remain fully compliant with your active DLP policies.

Below is an example of Sentra’s MPIP label automation in action, showing how we place sensitivity labels on data assets that contain Facebook profile URLs and credit card numbers belonging to EU citizens, which were modified in the past year:

Additionally, our continuous monitoring and real-time alerts empower organizations to immediately address policy violations – for instance, sensitive data with missing or incorrect MPIP labels – helping you maintain audit readiness and seamless compliance alignment.

A Data-Centric Security Approach to AI Adoption

By strategically combining robust sanitization and strong governance, you ensure your regulated data remains secure while enabling safe and compliant Copilot adoption across your organization. This approach aligns directly with the core principles outlined by NIST and the EU AI Act, effectively translating high-level compliance guidance into actionable, practical controls.

At Sentra, our mission is clear: to empower secure AI innovation through comprehensive data visibility and truly automated compliance. Our cutting-edge solutions provide the transparency and granular control you need to confidently embrace Copilot’s powerful capabilities, all without risking costly compliance violations.

Next Steps

Adopting Microsoft 365 Copilot securely doesn’t have to be complicated. By leveraging Sentra’s comprehensive DSPM solutions, your organization can create a secure environment where Copilot can safely enhance productivity without ever exposing your regulated data.
