Trustplane vs Aembit
Need your workloads to reach external systems, or need to control what callers may do at an API you own? Aembit focuses on workload access to targets; Trustplane adds request-level decisions before your business API. Evaluate the layers together.
01 What Aembit does well
A credible choice, and we will say so.
Aembit is a mature workload identity platform and the closest product to ours in intent. If you are shipping today and need broad coverage across clouds and SaaS targets, they are a credible choice and we will say so.
- Broad credential provider coverage across AWS, Azure, GCP, and SaaS targets, with prebuilt connectors.
- No application code changes: their proxy intercepts outbound traffic and handles authentication for the caller.
- A shipping product with customers, certifications, and distributed edge components for local credential injection.
02 The architectural difference
Opposite directions, from the same starting point.
Aembit — client side
Their proxy attests the workload, obtains a short-lived credential, and injects it into the outbound request. Your API receives a credential and trusts it.
Trustplane — provider side
Callers use a short-lived, identity-bound passport and a proof verified at your boundary against active policy. Proofs are consumed on use rather than granting portable bearer access.
Aembit protects your workloads on the way out. Trustplane protects your APIs on the way in. Both begin with the same step — attest the workload — and then diverge: they issue a credential from their vault so your caller can reach a target, we verify a proof so your API can judge a caller. If you are the API owner, evaluate incoming-request verification separately from outbound credential delivery.
Outbound access. Inbound authorization.
03 What that changes in practice
The same problem, answered twice.
Question
Aembit
Trustplane
Who enforces?
Aembit ·The caller's proxy, before the request leaves
Trustplane ·Your boundary, in front of your API
What does your API receive?
Aembit ·A short-lived credential it must trust
Trustplane ·A proof it verifies itself, valid once
If a request is captured in flight?
Aembit ·Replay exposure depends on the credential type and target’s controls
Trustplane ·The proof is already spent
Who has to deploy it?
Aembit ·Whoever owns the calling workload
Trustplane ·Whoever owns the API
That row is the whole point. A broker has to be adopted by every caller, including partners and agents you do not control, and it protects their outbound access rather than your inbound surface. Provider-side enforcement is one deployment, in front of the API you already own, and it checks callers that use the configured request-proof protocol. Caller integration and deployment need to be evaluated in a pilot.
04 Where each one belongs
Not either-or.
If your problem is your own workloads reaching many external targets, that is theirs to solve and we do not compete for it. If your problem is what arrives at your own API, that is ours, and no amount of broker coverage on the caller's side answers it. Many teams will end up with both: a broker for what their workloads reach, a boundary for what reaches them. What we do not have yet is their maturity — no certifications, no production references. That is a real difference today, and it is about our stage, not the architecture.
