Industries · Federal · Record Substrate

Your AI agents are acting inside an authorization boundary an auditor will ask you to account for.

Federal agencies are moving agentic systems into production inside their authorization boundaries. FISMA and NIST 800-53 expect an attributable record of that action. Built by a veteran-led team, the substrate produces it, inside your own boundary, designed to run air-gapped.

FISMA
Every federal system carries an authorization to operate against the NIST 800-53 baseline. Agents acting inside that boundary inherit its audit and accountability obligations.
NIST 800-53 · AI RMF
The control baseline (audit, accountability, access) plus the AI Risk Management Framework (AI 100-1) that governs federal use of AI.
OMB M-25-21 / M-25-22
The April 2025 federal governance and procurement requirements for high-impact AI; agentic deployments fall within their scope.

§ 01 The problem

Agents are acting inside the boundary. The trail is not.

The moment AI agents coordinate, handing work between models, tools, and humans, the trail of what acted inside the authorization boundary disappears. That is not only a technology problem. It is an accountability problem with audit consequences.

Who acted, under whose authority, and can you show an auditor? Agent handoffs leave no reviewable record. Action history lives inside vendor APIs, so when a model changes, the record changes with it, if it survives at all.

That is an operator problem. Subnet345 is built by a veteran-led team that runs a governed multi-agent operation every day.

§ 02 Why now

Can you account for what your agents did inside the boundary?

AI agents moved from controlled pilots to production faster than any previous federal technology. The governance acceptable in a pilot is not acceptable inside an authorization boundary. The audit floor is rising at the same time.

2023 to 2024

Pilots. Agents outside the boundary.

Single models in sandboxes, isolated from systems of record. The accountability question had not arrived because agents were not yet acting inside the authorization boundary.

2025 to 2026 · Now

Production. Agents act inside the boundary.

Multi-agent workflows act on federal systems. OMB policy requirements for high-impact AI are in effect, and the obligation to attribute action inside the authorization boundary is live.

2026 to 2027

Enforcement. The auditor asks.

The NIST 800-53 audit and accountability controls expect a complete, reviewable trail, and agent-specific control overlays for 800-53 are in development. The obligation to prove what an agent did inside the boundary arrives before the overlay that names it.

The audit question

If an agency inspector general asked you to reconstruct every action your agents took inside your authorization boundary last quarter, what would you show them?

§ 03 Use cases

Where the substrate lands first.

An attributable record is the precondition for deploying agents inside an authorization boundary at all. The agencies that build governed AI agents first carry an advantage into every audit that follows.

Mission work inside the boundary

Agents that draft, review, and reconcile against federal systems of record, with access attributed and reviewable. Throughput on the mission without losing the trail an audit expects.

In-perimeter and disconnected operation

Coordination, policy, and the record run inside your authorization boundary. The substrate is designed to run air-gapped: once installed, the substrate needs no route out, so it fits environments that cannot reach the open internet. An offline install path is on the roadmap.

Agency and contractor accountability

Shared accountability across handoffs: which agent acted, under whose authority, against which system. The record survives the seams between agencies, contractors, and systems.

§ 04 Against the frameworks

Measured against what the audit expects.

FISMA, the NIST 800-53 baseline, and the AI Risk Management Framework point toward a common expectation: action inside the boundary must be attributed, reviewable, and kept where the system is authorized. This material does not constitute legal or regulatory advice, and Subnet345 holds no FedRAMP authorization or ATO. Assess your obligations with your assessor.

§ 05 What we ship

The substrate, run by the team that operates one every day.

Subnet345 builds and operates the record substrate for AI agents. We do not advise on governance from the outside. We run an audited multi-agent operation ourselves, inside our own perimeter, on the same substrate we would stand up in yours.

01 / Preserve

Action inside the boundary

02 / Reconstruct

Who, what, under whose authority

03 / Avoid lock-in

Keep governance portable

Result

Audit-ready always

Built by a veteran-led team

The founding team includes U.S. Navy and U.S. Army veterans and operators who ran the infrastructure beneath national-scale security systems. We build for this environment because we came from it.

Immerse before we onboard

We stand the platform up inside your environment first, with your operators, against your telemetry, before you commit to a full rollout. We prove it before we scale it.

Transfer is the deliverable

You should be able to operate the platform without us at any point and keep running. We prove that condition before we step back, not in a proposal.

§ 06 Onboarding

How onboarding starts.

Every rollout begins with a structured conversation and ends with a transfer. No open-ended dependency, no shadow team after the sale. The engineer who stands the platform up is the one who trains your team.

01

Initial conversation · 45 minutes

Understand your current AI agent program, where it acts inside the authorization boundary, and whether this is the right fit for both organizations.

02

Governance assessment · Structured

A structured evaluation of your AI deployments against audit, incident, and accountability requirements, run inside your environment.

03

Design partner program

Early federal organizations become design partners, shaping the platform alongside the team that operates one every day.

The question we help you answer

Can you prove what your agents did inside the boundary, and under whose authority?

If you cannot answer that today, and an auditor asks it tomorrow, Subnet345 is the substrate that changes that answer, inside your own boundary.
