Memory your agents can act on — and prove they were right to.

Governed Memory sits between your AI agents and what they remember about your customers. Every write is provenance-tracked, scanned for injection attempts, and stamped trusted, untrusted, or quarantined — before an agent ever reads it.

The problem

Agent memory is a new kind of attack surface

The moment an agent can write something to memory and act on it later, that memory becomes part of your attack surface. A support ticket, a scraped web page, an inbound email — any of them can carry an instruction disguised as a fact. Left ungoverned, that instruction sits in your vector store indistinguishable from anything else, waiting for an agent to retrieve it and treat it as ground truth.

And once an agent takes an action on the strength of a memory, there's often no record of which memory it relied on, or why the system considered it trustworthy enough to act on.

  • Injection

    A poisoned support ticket instructs an agent to grant a free upgrade or reveal a secret — and the source field says it's trustworthy.

  • Inference creep

    An agent's own guess about a customer gets retrieved later and treated as a verified fact, with nothing marking it otherwise.

  • Cross-tenant leak

    One tenant's customer data surfaces in another tenant's session because nothing enforced the boundary at query time.


How it works

One pipeline, four checkpoints

Every write and every read passes through the same four stages, in order — there's no side door.

01

Write Governor

Every write is tagged with its provenance — who said this, and how sure are we — scanned for injection patterns, and deduplicated against what's already known, before it's ever stored as trusted.

02

Retrieval Engine

Vector and lexical search are fused into one ranked result set, then filtered by a privilege gate: untrusted and quarantined memory doesn't reach an agent unless it's explicitly asked for.

03

Policy Engine

You define which source types can justify which purposes. A refund, a sent email, an escalation — each can require memory that clears a bar you set, not one the model assumes.

04

Audit Trail

Every write, retrieve, quarantine, and policy check is logged as a hash-chained event. Each entry links to the one before it, so tampering with history breaks the chain visibly.


What's live today

Built, tested, and running — not a roadmap slide

Tenant isolation

Cross-tenant reads return nothing — not an error, not a leak. Enforced at the query, not the application.

Injection-resistant writes

Content is scanned regardless of what the source claims to be. A "trusted_system" label doesn't buy a pass.

Governed retrieval

Untrusted and quarantined memory stays out of an agent's hands unless it's asked for by name.

Purpose-bound policy

Decide per purpose which sources are good enough to act on — no config needed for the defaults.

Tamper-evident audit

SHA-256 hash chain over every governance decision, reviewable after the fact.

REST API + Python SDK

Self-host the server yourself; pip install a client with zero third-party dependencies.


Status

Where things stand

Live

Core governance engine, REST API, and Python SDK — built, tested, and self-hostable via Docker today.

In review

A trained ML injection classifier, running alongside the existing heuristic scanner rather than replacing it.

Next

A provenance graph, so purging one memory can cascade through everything derived from it.
