Corsha

Corsha addresses a specific and genuinely underserved problem in API security: the machine identity and service-to-service authentication layer, where long-lived static API keys sitting in configuration files represent a persistent credential theft risk most API security vendors, focused primarily on traffic inspection, do not directly solve. By implementing dynamic, rotating machine credentials, Corsha eliminates the long-lived static key as an attack surface entirely. This focus has earned genuine credibility in defence, government, and financial services environments.

The honest and important limitation is scope: organisations expecting API discovery, vulnerability testing, and general runtime threat detection from this single tool will find significant gaps requiring additional dedicated tooling.

The verdict: right for organisations specifically concerned with machine identity and service-to-service authentication risk. Organisations wanting a broad, full-lifecycle platform should evaluate Salt Security or 42Crunch, potentially alongside Corsha for the specific machine identity layer.
