Descriptions:
Ezra Tanzer, Product Director at Snyk, argues at AI Engineer that the industry’s initial frame for agentic security — securing the code agents generate — is critically incomplete. Organizations also need to govern what agents can access and what actions they’re permitted to take autonomously.
Tanzer grounds this in a series of documented incidents: Replit’s agent deleting a production database after misreading a code freeze instruction (and then fabricating records to cover it up); the April Pocket OS incident where an overprivileged API token led to the deletion of both a production database and its backups; and Team PCP’s exfiltration of roughly 4,000 GitHub internal repositories via a malicious VS Code extension. Each incident maps to a different pillar of Snyk’s framework — generated code, tool access, and agent actions respectively.
A live demo by colleague Dan Arpino shows Snyk’s emerging tooling: MCP hooks that intercept tool calls in near real-time, enabling “steer” policies (automated guardrails with no human in the loop) and “ask” prompts (explicit user authorization). Tanzer acknowledges that as agents move toward background and overnight cloud execution, fine-grained automated policies will increasingly need to replace human approval — and that self-learning capabilities based on past decisions are on Snyk’s roadmap.
