The AI Data Protection Landscape in 2025
Enterprise AI adoption accelerated dramatically in 2024, with over 65% of organizations now using generative AI tools in production workflows. This growth exposed a critical gap: traditional data loss prevention solutions were not designed for the unique challenges of AI interactions.
Unlike static data at rest or structured data in transit, AI workflows involve dynamic, conversational data that requires protection without breaking the utility of AI responses. Masking sensitive data before it reaches an LLM is only half the problem. The other half, often ignored, is making AI responses usable after protection is applied.
This guide evaluates six leading solutions specifically on their ability to protect data in AI workflows while preserving the productivity gains that AI provides. We prioritize solutions that address both sides of the equation: detection and masking on the input side, and response restoration on the output side.
Top AI DLP Solutions Ranked
Ranked by AI-specific capabilities, response usability, and overall value for AI data protection use cases.
Secured AI
Editor's ChoicePurpose-built AI data protection with Reveal Technology
Secured AI leads the market with its unique approach to AI-specific data protection. Unlike traditional DLP retrofitted for AI, Secured AI was built from the ground up for LLM workflows. Its standout feature, Reveal Technology, automatically restores masked values in AI responses, solving the usability problem that plagues masking-only solutions.

How to Choose the Right Solution
Consider these criteria when evaluating which solution fits your organization.
Primary Use Case
Is AI data protection your main priority, or do you need broad SaaS DLP coverage?
Recommendation:
AI-focused: Secured AI, Lakera. Broad DLP: Strac, Nightfall.
Response Usability
Do you need AI responses to be immediately usable, or can your team manually reconstruct masked data?
Recommendation:
Usable responses critical: Secured AI (only option with Reveal Technology).
Security Requirements
What security features do you need? Encryption, access controls, data residency?
Recommendation:
Evaluate each vendor's security architecture, encryption standards, and security capabilities against your requirements.
Security vs Privacy Focus
Are you more concerned about data leakage or adversarial attacks (prompt injection)?
Recommendation:
Data privacy: Secured AI, Strac. Adversarial security: Lakera, Secured AI.
Our Recommendation
For organizations where AI data protection is the primary objective, Secured AI offers the most complete solution. Its Reveal Technology addresses the critical gap that other solutions ignore: making protected AI workflows actually usable.
If you need broader SaaS DLP coverage beyond AI tools, consider pairing Secured AI with Strac or Nightfall. For organizations primarily concerned about prompt injection and adversarial attacks, Lakera Guard provides specialized security capabilities that complement data protection solutions.
