Overview
Lakera developed prompt-injection defense and runtime AI security products, including Lakera Guard and the Gandalf adversarial research game. The Zurich-based startup raised $10M in 2023 and $20M Series A in 2024. Check Point agreed to acquire Lakera September 2025 and completed the deal October 22, 2025. Its audited financial statements disclose approximately $201.8M in total acquisition consideration.
Runtime protection must be combined with secure identity and least privilege; a prompt filter alone cannot guarantee protection against unauthorized AI agent actions.
Why Lakera is interesting
Lakera shows the third, runtime-defense layer beyond Dreadnode's testing and Fiddler's behavior monitoring: detecting malicious inputs and agent misuse while the system operates.
Product & use cases
Prompt injection defense and runtime security classification for AI applications and agents.

Competitive landscape
Edge: Specialization in adversarial AI threats and runtime guardrails; coverage is not a guarantee against novel attacks.
The closest alternatives differ by whether they investigate existing telemetry, orchestrate incidents, evaluate AI agent behavior, or prevent adversarial exploitation. Selection should be based on representative task-level tests, deployment permissions, data control and total ownership cost.
