Use cases
Governance for every team
ActantOS sits between agents and the systems they touch — giving security, platform, and compliance teams independent runtime control.
Security operations teams
SecOps & incident response
Autonomous agents can execute shell commands, read credential files, and call external APIs without a centralized kill switch or forensic trail.
ActantOS intercepts every tool call, enforces Cedar policy, activates kill switches per agent or tenant, and records a hash-chained audit timeline for investigation.
- Instant deny on credential path access
- Kill switch blocks all actions for a compromised agent
- Session timelines with request_id and risk_class
Teams running Pi, MCP, or custom agents
Platform engineering
Agents connect to dozens of MCP servers and internal APIs with no unified identity, manifest pinning, or SSRF protection at the tool layer.
Route MCP clients through the ActantOS gateway or wrap Pi tools with guarded adapters. One decision pipeline for every runtime.
- MCP manifest drift detection
- SSRF blocklist before policy evaluation
- Model- and framework-agnostic enforcement
GRC and compliance officers
Compliance & audit
Post-hoc log reviews cannot prove what an agent was allowed to do at decision time, or whether a human approved a high-risk action.
Every intercept, policy decision, approval, and tool result is recorded immutably. Export to SIEM and WORM storage is on the enterprise roadmap.
- Tamper-evident Postgres hash-chain (MVP)
- Approval records with one-use tokens
- Structured evidence for SOC 2 and ISO 42001 programs
Get started
Install the kernel. Run Stage 2 ops.
Stage 1 and Stage 2 are done when tests pass. Run Quiet Open-Core locally, then use dashboards for filters, metrics, policy dry-run, and webhook approvals.
