For engineers

Every agent action,
decided first.

Memnox sits between your AI agents and your systems and returns one of three answers, allow, block, or ask a human, before anything runs. It understands code; it never writes it.

No model in the decision path

Verdicts come from a deterministic policy engine. Same action, same decision, every time. Security needs guarantees, not probabilities.

Six languages, one gate

TypeScript, Python, Go, Java, Rust and Swift clients all ask the same runtime, so a rule holds wherever it is called from.

Zero infrastructure to start

No account, no API key, no network call. The solo path never talks to a server that isn't on your laptop. Postgres and Redis when one process stops being enough.

It watches before it enforces

The first run decides nothing. Read the audit log, then re-run with --enforce once the calls look right.

Provable, not merely logged

Every decision appends to a hash-chained log carrying the policy version that decided it. memnox audit verify shows whether a single record was touched.

Apache-2.0, yours to run

Read every line of the thing governing your agents. Runs on a laptop, in your cluster, or on a network that never leaves the building.

npx memnox setup
 
# Wrote starter policies to memnox.policies.yaml
# Detected: payments, database migrations, CI/CD
# Restart your editor and it is governed.

One command scaffolds policies from what it detects in the repo, registers a local agent and starts the runtime.

Open source and cloud

The runtime enforces.
The cloud understands.

The gate that decides what an agent may do is Apache-2.0 and runs on your machines. The understanding of your organization is what the cloud keeps current. Each is complete on its own, and adopting one never holds the other hostage.

Memnox Runtime

Everything that decides is open: the same gate whether one laptop runs it or the whole company does.

  • The deterministic policy gate, approvals and the hash-chained audit log
  • Runs with one command, no account, no API key, no network call
  • Scales to a team on Postgres and Redis, same policies, same verdicts
  • Yours to read, run and fork

Managed · the shared understanding

Memnox Cloud

Everything that understands is managed: the picture of the business that every person and every agent works from.

  • One living graph of goals, ownership, decisions and authority
  • The review queue, where a pattern becomes a rule a named person approved
  • Every AI worker registered, bounded and accountable in one place
  • Approvals routed to owners, the record exported to your security team

Sensitive work can stay home.

Agents and the gate can run entirely in your environment while the cloud manages policies, the fleet and the picture everyone shares. Nothing about the local path changes when the organization adopts the cloud, and the record is always yours to export.
