Corsha

Corsha builds a platform that issues dynamic, short-lived machine identities and layers multi-factor authentication onto API calls between systems, targeting a gap that legacy IAM tools were never built to cover: most API and machine-to-machine traffic still runs on static, long-lived credentials like API keys and certificates that are easy for attackers to harvest and replay. Corsha’s core mechanic pins API access to a per-call, one-time credential generated for a specific trusted machine, a materially different approach from API gateways or WAFs that inspect traffic patterns without addressing the underlying credential problem.

Founded in 2017 and based in Vienna, Virginia, Corsha raised a Series A and a follow-on extension round, including investment tied to Venafi’s Machine Identity Management Development Fund, a vehicle Venafi (an established machine-identity vendor) uses to back complementary companies in the space. That participation is a real, if indirect, industry validation signal rather than a direct endorsement of product efficacy.

The company markets itself as delivering “MFA for machines,” a genuine category framing since traditional human MFA methods (push notifications, TOTP codes) have no direct analog for machine-to-machine and CI/CD credential exchange. Adoption to date appears concentrated in federal, industrial, and DevOps-heavy environments where API sprawl and long-lived secrets are recognized operational risks, rather than broad horizontal enterprise deployment.
