Outerlimit raises $16M for agent zero trust

Outerlimit emerged from stealth with $16 million in pre-seed funding to secure the agent action layer, the company announced September 22. Its funding announcement describes a three-stage path—discover, observe, enforce—and says it is working with Fortune 500 and FTSE 100 brands; those are company claims, not proof of deployed control. Builders should file this as a signal that agent-security budgets are moving from prompt filters toward tool authorization, alongside the case for treating agent security as a deployment constraint.
