Autonomous engineering needs autonomous security.
MatterSec exists because software work is changing from human-only authorship to agent-executed labor. That new labor needs a security supervisor that can act.
The agent ran without a witness. Matt is the replay.
Agents are becoming software engineers.
They do not just autocomplete code. They take tasks, modify repos, run commands, open PRs, and work while humans are elsewhere.
Security cannot remain a post-merge ritual.
Autonomous code needs security controls inside the loop, where risky changes are created and can still be stopped.
The reward must be earned safely.
As coding agents optimize for tests, tickets, and PR acceptance, teams need a way to verify the success signal was not gamed.
Humans should supervise the system, not every edit.
MatterSec gives humans a control room. Matt handles the repetitive enforcement path and explains the exceptions.
Every autonomous run should be replayable.
If an agent changes code that matters, the team should know what happened, why it happened, and what action was taken.
