Lakera

AI security platform for LLM prompt injection protection

freemiumupdated Jul 16, 2026

Lakera is an AI security platform protecting LLM applications against prompt injection, jailbreaks, data leakage, toxic content, and PII exposure. Lakera Guard provides a real-time API that screens prompts and outputs in under 2ms latency. Trained on the world's largest prompt injection dataset from Gandalf, a public red-teaming game. Deploys as an API proxy or SDK integration with zero model access required. Used by enterprises to secure customer-facing AI applications in production.

Lakera provides security for LLM applications, addressing the growing threat of prompt injection attacks, jailbreaks, and data leakage in production AI systems. The platform is trained on the world's largest prompt injection dataset, collected through Gandalf — a public red-teaming game that has attracted millions of attack attempts.

Lakera Guard is the core product — a real-time API that screens incoming prompts and outgoing responses for security threats. It detects prompt injection attempts, jailbreak patterns, PII leakage, toxic content, and off-topic usage with under 2 milliseconds latency per request.

The platform deploys as an API proxy sitting between users and LLM providers, or integrates via SDK into application code. No access to the underlying model weights is required, making it compatible with any LLM provider including OpenAI, Anthropic, and self-hosted models.

Enterprises use Lakera to secure customer-facing chatbots, AI assistants, and agentic applications. The dashboard provides analytics on threat types, attack patterns, and blocked requests, helping security teams understand their AI threat landscape.

Comparisons

Lakera vs Prompt Security: AI Defense Plane or Workforce and MCP Control?

Lakera and Prompt Security both protect generative-AI interactions, but their current product boundaries are no longer those of two independent point startups. Lakera is now part of Check Point's AI Defense Plane, where workforce visibility, agent discovery and risk assessment, runtime AI Guardrails, and red-team services are documented as connected layers. Prompt Security is owned by SentinelOne and continues to present focused controls for employee AI use, homegrown applications, code assistants, and agentic/MCP traffic. Lakera is the stronger default for an enterprise building a broad AI security program. Its current documentation connects application and agent runtime protection to workforce governance and agent posture, while retaining a standalone Guard API tier and a self-hosted/on-prem option. Prompt Security is the sharper specialist when the immediate buying problem is shadow AI, code-assistant policy, or MCP gateway enforcement, especially for a SentinelOne-aligned security organization.

Teleport Beams vs Lakera: AI Security Approaches Compared

Teleport Beams and Lakera both address AI security but at different layers. Teleport Beams provides cryptographically verified runtime environments for AI agents accessing production infrastructure, while Lakera protects against prompt injection and content threats at the model interaction layer. Together they represent complementary defense-in-depth strategies for securing AI deployments.

Lakera vs garak — LLM Security Tool Comparison
