Why teams choose MTE Relay

Quantum resistant by design

MTE uses NIST approved DRBGs to substitute your data with random values that are never derived from it. There is nothing to harvest and decrypt later.

How MTE works →

No application rewrites

The relay is an HTTP(S) proxy in a Docker container. Stand it up in front of your backend and keep your API exactly as it is.

Read the overview →

Client SDKs included

Native libraries for JavaScript, iOS, Android, Flutter, and Blazor make the client side a simple change.

Built for low latency

MTE adds a small, roughly constant overhead per request, and v5 cuts it further: up to 39% lower latency and 37% more requests per second than v4.
