Workload identity platforms govern what your services can reach. A boundary governs what can reach your services. They're complementary — and you probably need both.

Tools like Aembit and Teleport solve the outbound problem: a workload needs a credential to call AWS, a database, or a third-party API, and the platform issues it just-in-time based on attested identity. That eliminates stored secrets on the client side.
But once a request arrives at your API, someone has to decide whether to serve it. That inbound decision — per request, at the boundary, with a verifiable proof — is a different problem, and it's the one Trustplane solves.
The two layers share an idea — identity should be proved, not stored — and they compose cleanly. A workload can attest itself to fetch an outbound credential, and separately present a proof when it calls your API. One direction protects your dependencies from your workloads; the other protects your APIs from everything else.
We wrote detailed, honest comparisons of where each tool fits: see our pages on Aembit, Teleport, and Descope.
Every request proves itself — no keys, anywhere.
Put the boundary in front of one API and measure it yourself.
