Why Mutual TLS

Ordinary TLS proves the server to the client and stops there; the server rarely knows who is really calling it. In a zero-trust network that is not enough — every service should prove its identity to every other service, on every connection.

Mutual TLS does exactly that, but it has always been painful in practice: issuing a certificate to every workload, and rotating them all before they expire, is the part teams dread and therefore avoid.

See zero-trust mTLS in action — both sides prove who they are, a rogue is rejected, and certificates rotate themselves with no downtime.

A BetterSign Identity for Every Service

BetterSign gives each service a VLAD and issues it a short-lived X.509 identity — an SVID — rooted in a provenance log rather than a static certificate authority. Both ends of a connection present their SVID and verify the other, so a call is accepted only when both identities check out.

Because the trust root is a plog, rotating a service key or even the issuing authority is a signed entry that every verifier converges on — no CA re-key drama, and no fleet-wide certificate push.

Drop It In Front of Anything

The bettersign proxy adds mutual TLS to services that were never built for it. It terminates SVID-authenticated TLS at the edge, re-establishes mTLS to the backend, and forwards the verified client identity downstream as an X-Forwarded-Client-Cert header, so your application can make authorization decisions from a caller identity it can actually trust.

The result is a zero-trust mesh you can adopt incrementally, without rewriting services to speak mTLS themselves.
