Comparison
Acquired by Check Point, Sep 2025 ($300M)
Lakera pioneered low-latency prompt-injection detection. SoterAI delivers that plus RAG security, an agent firewall, policy modes, self-hosting, and signed audit trails in one product.
Lakera (now part of Check Point) is a purpose-built, cloud-hosted API for prompt injection and jailbreak detection, with a well-known red-team community (Gandalf) and broad language coverage. SoterAI is a broader runtime security command layer: it guards both input and output, scans and quarantines RAG documents, authorizes agent tool calls, enforces policy modes, and ships HMAC-signed audit exports — and it can run fully self-hosted in your own VPC.
Lakera has deep, purpose-built adversarial detection with strong brand maturity, a large public attack corpus, and Check Point's enterprise go-to-market.
