Lakera (Lakera Guard, Lakera Red) vs HiddenLayer (AISec Platform, Model Scanner): Cost and Coverage
Side-by-side comparison across price, pricing model, OWASP LLM Top 10 coverage, deployment and headquarters. Verified 2026-06-19.
Headline verdict
Different problems. Lakera Guard sits in the request path and detects prompt injection at runtime. HiddenLayer scans models for tampering and runs adversarial-ML detection. Many buyers need both. If forced to pick one, choose by where the threat lives: Lakera for the prompt, HiddenLayer for the model.

If you are on one and considering the other
These are complementary rather than substitutable. Replacing one with the other usually leaves a coverage gap; treat the comparison as a layering decision instead.
