Runtime governance · self-hosted · deterministic

Every AI action.
Judged. Blocked. Proven.

Everyone verifies who your agent is. NOCTRYS governs what it does: every action checked against your policy in real time, the dangerous ones blocked, and all of it sealed into proof you can verify yourself.

Internal benchmark: our own OWASP Agentic test battery and reference deployment. Not a third-party certification.

The gap

Agents don't answer. They act.

A chatbot returns text. An agent moves money, reads your customer tables, calls tools, and delegates to other agents, on its own, over untrusted input. The industry is busy proving an agent's identity at the perimeter. Almost no one is governing its behavior at runtime. That's the gap NOCTRYS closes: we don't try to read the model's mind; we gate its hands. Deterministic, inline, and fully observable no matter what happens inside the model. None of this is hypothetical: see the documented incidents.

How it works

Three layers between your agents and the damage.

01

Govern

Deterministic least-privilege rules on every action. No model in the enforcement path, so the verdict is reproducible and immune to a clever prompt.

  • allowlist
  • arg + output schema
  • spend caps
  • rate limits
  • signed human approval
  • egress control
  • path policies
  • delegation limits
  • signed payment mandates
02

Detect

Two individually allowed actions can still be an attack. NOCTRYS watches sequences, provenance, and per-agent baselines to catch what static rules can't.

  • exfiltration
  • prompt injection
  • indirect injection
  • info-flow control
  • drift
  • memory poisoning
  • tool rug-pull
  • canary tripwires
03

Prove

Every action is sealed into a hash-chained ledger, anchored on AERE and cosigned by independent witnesses, so no one, not even us, can rewrite the record or tell two different stories about it. Anyone can verify a NOCTRYS seal for themselves. Every deployment also feeds a shared threat network: an attack blocked at one customer protects them all.

  • tamper-evident log
  • AERE anchor
  • witness cosigning
  • public verifier
  • execution receipts
  • collective defense
  • assurance levels
  • compliance report
Deployment

Runs where your agents already run.

One enforcement core, three ways to run it: all self-hosted, inside your infrastructure. Your agents route through it; only a 32-byte proof ever leaves.

MCP

Proxy / stdio

Installable as an MCP server your agent runtime spawns. Every tools/call is governed before it runs.

HTTP

Sidecar

Agents POST /v1/intercept; a live compliance console streams every decision as it happens.

GO

Single binary

One static binary for the latency-critical path. Trivial to self-host: no runtime, no dependencies.

▪ self-hosted: NOCTRYS never sees your data; only a 32-byte hash of the log is anchored on-chain.
Standards & frameworks

Built to the standards enterprises are measured against.

NOCTRYS maps its controls to the regulations and frameworks your auditors, regulators, and security teams use to judge you, so an agent deployment can clear review instead of stalling in it. We are early-stage and onboarding design partners: these are engineering mappings and alignments, not certifications.

The regulatory clock

High-risk agent rules move to December 2027. The engineering can’t wait that long.

Under the EU Digital Omnibus, now law as Regulation (EU) 2026/1744, high-risk AI-agent obligations are postponed to 2 December 2027, while transparency duties and the AI Office apply from August 2026. But a believable, intervenable audit trail is an architecture, not a document. NOCTRYS makes you provably ready, early and by design, not in a last-minute scramble. Fines still run to €15M or 3% of global turnover.

Why NOCTRYS

Not a gateway. Not a model guard. A governor with proof.

GATEWAYS

Route and rate-limit calls. They see traffic, not whether a sequence of allowed actions adds up to theft.

MODEL GUARDRAILS

Read prompts with another model. Probabilistic, and blind the moment the agent leaves the chat box to take an action.

NOCTRYS

Judges behavior on the action plane, deterministically and fail-closed, and cryptographically proves what it did. The part regulators actually ask for.

The pilot

Free pilot terms. A two-week, self-hosted integration. You keep the tamper-evident audit log and the AI Act compliance report from day one. In exchange, we ask for your honest feedback.
