Agent Security and Governance
Running agents without giving away more than you meant to. These pages cover scoped credentials and key rotation, permission boundaries, prompt injection and tool poisoning, sandboxing, data retention, audit trails, and the review process around autonomous output. Fast.io supports this with scoped API keys, granular workspace permissions, encryption in transit and at rest, and an append-only audit log. It is not SOC 2, ISO 27001, or HIPAA certified, and it runs on certified infrastructure partners rather than claiming those certifications itself.
Coverage assumes an agent with real access rather than a demo, so the pages spend their time on blast radius: what a confused or compromised agent could reach, how to shrink that before it matters, and what evidence you would have afterwards. They describe specific controls rather than certifications, and they say which ones are worth putting in place first when you cannot do everything at once.

Why Google Drive Version History Fails for Autonomous Agents
Google Drive version history is designed for human editing, but it fails when autonomous agents write to files at high frequency. Rapid API writes trigger the 100-version rollover limit, purging human revisions and causing review fatigue. Teams can solve this by using isolated workspaces, structured audit logs, and remote Model Context Protocol configurations.
