Trial
Lakera Guard is a real-time API that detects prompt injection, jailbreaks, and data leakage with 98%+ accuracy and sub-50ms latency. Acquired by Check Point in September 2025, it's now integrated into Check Point's Infinity Platform, CloudGuard WAF, and GenAI Protect. Its detection models are trained on 80M+ adversarial prompts from the Gandalf community game.
Why It Matters for AI-Assisted Development
Prompt injection is the #1 risk on OWASP's LLM Top 10. Lakera Guard provides a deployable defense layer:
- Dual-layer ML architecture: Supervised ML engine, unsupervised ML engine, and patent-pending semantic engine for detection.
- 100K+ new adversarial samples daily from the Gandalf community (1M+ players) — continuously improving detection.
- MCP security: Explicitly checks MCP server inputs/outputs for injection and credential leakage.
- 100+ language support with sub-50ms latency and <0.5% false positive rate.
Strengths
- Highest published detection accuracy (98%+) for prompt injection
- Sub-50ms latency makes it viable for real-time enforcement
- Backed by Check Point's enterprise security infrastructure
- Free tier available at platform.lakera.ai
- SOC2, GDPR, NIST compliant
Limitations
- Now part of Check Point — enterprise pricing and procurement complexity
- API-based approach adds a network hop to every LLM interaction
- Prompt injection remains fundamentally unsolved; even 98% detection leaves a gap
