Lakera Guard is an AI agent security platform that discovers enterprise agents, assesses their risk, and enforces runtime protection against prompt injection and data leaks.
About
Lakera Guard is a security platform from Lakera that protects enterprise AI agents throughout their lifecycle, from initial discovery to real-time runtime enforcement. It addresses a problem many organizations now face: employees and teams are deploying AI agents across tools, APIs, and workflows faster than security teams can inventory or govern them, creating blind spots around what those agents can access and what actions they can take.
At a high level, Lakera Guard works in three stages. It first connects to an organization's agent ecosystem — including cloud, low-code, and custom environments — to reveal which agents and MCP-connected tools exist, even ones that were never formally registered. It then assesses each agent's risk based on its configuration, data access, connected MCP servers, and level of autonomy. Finally, it enforces policies and runtime guardrails that block prompt injection, jailbreaks, data leakage, and unauthorized agent actions. Lakera states that the product deploys in minutes, requires no changes to existing models or prompts, and adds no meaningful latency, with sub-50 ms runtime latency cited on its site.

Pricing & Fees
- Pricing: Not publicly listed on the pages we reviewed; check the official site for current plans.
- Getting started: The site offers a "Start for free" option alongside demo bookings, so prospective users can begin without an immediate sales conversation.
- Part of a broader portfolio: Lakera Guard sits within Lakera's AI security suite, which also includes Workforce AI Security for employee AI usage and expert-led AI Red Teaming services.
- Focus risks: Prompt injection (direct and indirect), jailbreaks, AI data leaks, toxic content generation, compliance and regulatory risks, and multilingual or multimodal attacks.
Who It's For
Lakera Guard is aimed at security engineers, CISOs, and AI platform teams at organizations building or operating AI agents, copilots, and RAG-based applications. It fits teams running conversational agents, document or RAG agents, connected agents using MCP servers, and GenAI gateway deployments. It is especially relevant where agents have access to sensitive data, internal APIs, or elevated privileges — situations where a misdirected or compromised agent could expose information or trigger unauthorized actions — and where security review must keep pace with rapid AI adoption.
