TL;DR

The credential layer is every surface holding a secret : Code, cloud, laptops, SaaS, collaboration tools, and public sites all hold plaintext credentials, and a single key can travel through all of them during its lifetime.

Six controls form a connected program : Discover, prioritize by access risk, connect to owners, remediate copies, prevent spread, and detect harvesting with honeytokens, working alongside IAM, PAM, vaults, EDR, and cloud security.

Endpoints and AI agents raise the stakes : Developer laptops average about 150 secrets each, and agents can read files, run commands, and call MCP servers, so credential scope and deterministic controls matter more.

What is credential layer security?

Before we define the full credential layer, let's start by defining "credential." In the context of information technology, we define a credential as any piece of data that grants access to a system, service, resource, or data.…
