Security is no longer optional.

Rexion is a research lab building autonomous agents that find vulnerabilities at the speed of code being written.

Two instruments. One method.

The same reasoning engine, tuned to two tempos — a deep audit that reads for hours, and a continuous reviewer that reads every diff as it lands.

Part I available

Athena
