A firewall is a policy layer
For coding agents, a useful firewall starts with repository policy: protected files, command restrictions, workflow change review, secret redaction, and trusted approval paths.
It must fit developer workflow
Controls that slow every edit will be bypassed. CapitalGuard generates focused guardrail starters that developers can install around high-impact paths first.
Detection comes before prevention
The right policy depends on the exposure report. CapitalGuard scans first, then turns the findings into practical controls for the buyer's current scope.
