Runtime AI-agent governance and enforcement platform with sub-20ms policy checks, kill switches, and compliance-ready audit logs.

Runtime Policy Enforcement: Semantic check plus policy eval on every tool call in a p50 of under 20ms, either passing, holding, or denying the action before it touches the real world.
Emergency Kill Switch: One-click, server-side stop that halts any single agent or an entire org's fleet in under 6ms (measured).
Immutable Audit Trail: Cryptographically hash-chained, append-only records of every attempted action, classification, and decision — verifiable end-to-end for auditors.
Real-time Traces: Structured logs capturing input/output, model, token counts, latency percentiles, and cost per action with a searchable timeline and parent-child span tree.
Tiered Autonomy Governance: Assign each agent observe, advise, act-with-approval, or autonomous level, auto-apply the matching policy bundle, and flag drift when an agent outgrows its guardrails.
Real-time Cost Circuit Breaker: Synchronous spend caps per org, agent, user, or workspace across 1m/1h/1d/1mo windows, enforced in the policy path with burn-rate alerts before the budget is breached.
Compliance Framework Coverage: Auto-generated reports for SOC 2 Type II, HIPAA, GDPR, ISO 27001, EU AI Act, PCI DSS, and NIST AI RMF with row-level PostgreSQL isolation and PII scrubbing.
Multi-Framework SDKs: Python and TypeScript instrumentation that plugs into OpenAI, Anthropic, LangChain, LlamaIndex, CrewAI, AutoGen, and MCP in about three lines of code.

Enterprise AI Rollout: Give a platform team a single control plane to safely deploy autonomous customer-support, data-analyst, and code-review agents in production.
EU AI Act & SOC 2 Evidence: Generate cryptographically signed logs and pre-mapped reports auditors can accept for high-risk AI systems.
Prompt-Injection & Data-Exfil Defense: Block agents from calling risky tools or exposing PII when a user prompt or document tries to hijack their behavior.
Agent Cost Control: Cap spend synchronously per agent, team, or workspace so a runaway loop or misconfigured model cannot burn the monthly budget.
Air-Gapped or Regulated Environments: Self-host the full stack on Docker or Kubernetes inside a defense, health, or finance network with zero customer data leaving the perimeter.
Human-in-the-Loop Approvals: Route irreversible actions (payments, deletes, external sends) into a hold queue that pauses the agent until an approver signs off.
