Keycard vs. GitGuardian

Keycard is a cybersecurity startup providing a specialized Identity and Access Management (IAM) platform designed specifically for AI Agents and autonomous applications. Their software helps enterprises securely deploy AI agents into production by replacing traditional static security credentials with dynamic, identity-bound, task-scoped tokens.

GitGuardian is the credential layer security platform for securing the secrets that let code, machines, and AI agents access systems and act as trusted identities. API keys, tokens, passwords, and other secrets carry real access. When they leak, attackers do not need to break in, they can log in. The scale of the problem keeps growing: 28.6 million new secrets were exposed on public GitHub in 2025, a 34% year-over-year increase and the largest jump on record. GitGuardian finds the secrets that matter across an organization's entire secrets surface, inside and outside the perimeter.
