Why it matters
Third-party AI agents embedded in existing SaaS evade identity-based controls by default, creating an ungoverned attack surface that defenders cannot see or authenticate.
An analysis tied to the 2026 State of Agent Security Report argues that enterprises face a 'third-party agent problem': of roughly 1,280 third-party products embedding AI, only about 282 sit behind single sign-on, leaving some thousand AI agents invisible to identity infrastructure because they never authenticate through it. The piece frames a shift from securing first-party AI the company chose to governing agents that arrive embedded in software already in use, without an explicit procurement decision.
