Sift Debuts Fail-Closed AI Governance

The backstory is outrageous, but the product thesis is the real signal: once agents can act, governance becomes part of the stack.

• –The official Sift site frames it as a deterministic layer between intent and execution, with Ed25519 verification, ACL/risk gating, replay protection, signed allow/deny receipts, and fail-closed behavior.
• –The alpha numbers are impressive on paper - 143 req/sec, zero fail-open events, 100% blocked adversarial attacks - and the outside LLM's 8/10 score is a clever hook, but it is still self-reported.
• –Strato-Sift's operator/auditor/red-team loop is the strongest proof point, because it shows the control plane being dogfooded rather than merely marketed.
• –This is aimed at the right beachhead: n8n, LangGraph, CrewAI, fintech/crypto ops, and other workflows where a bad tool call has real-world consequences.
• –The story will get attention, but adoption will depend on whether Sift is light enough to sit in the path of every action without becoming a bottleneck.
