Sentinel · Decision-Layer Security

Stop the breach before the human commits it.

Most incidents aren't a clever attacker. They're a tired, trusted person taking one irreversible action under pressure. Inner Perimeter watches the last six inches between a human and production — and intervenes at the exact moment of risk.

The blind spot

Your perimeter is hardened. Your people are not.

Firewalls, IAM, and runbooks all assume the human at the keyboard is calm and certain. At 2am, mid-incident, under a VP breathing down their neck, they aren't.

  • The breach is a decision. The drop-prod command, the wire transfer, the prod creds pasted into a chat — a person chose it, fast, under load.
  • Pressure removes judgment. Stress narrows attention. The exact moment risk is highest is the moment people see least.
  • Approvals don't catch it. The reviewer is just as tired, and rubber-stamps to keep the incident moving.
  • Logs tell you after. Every audit trail is a postmortem. By the time it's written, the action is irreversible.

Guardian Intervention Layer

It steps in at the moment of the action, not after the log.

The Guardian Layer sits read-only beside your CLIs, consoles, and approval flows. When a high-risk action is forming, it intervenes with the lightest touch that still stops the mistake.

01 / SENSE

Watch the action form

Reads the intent behind a command, a click, or a transfer — without sitting in the critical path.

02 / SCORE

Price the risk live

The HRI Engine scores the action and the actor in real time: how destructive, how irreversible, how fatigued.

03 / INTERVENE

The lightest stop

Low risk: silent. Medium: a calm context prompt. High: a hold with two-key confirm and a named second set of eyes.

04 / LEARN

Tighten the loop

Every intervention feeds the model. The perimeter gets sharper to your environment with every shift.

HRI Scoring Engine

A live Human Risk Index for every action.

Not a static role or a yearly training score. A real-time read on the risk of this person, taking this action, right now.

How it deploys

Beside your stack, never inside the blast radius.

Read-only by design. Inner Perimeter runs on its own control plane (powered by a Base44 backend) and connects out to your environment — so the thing that guards production can never take it down.

# Inner Perimeter · control plane (Base44) → your environment
guardian.watch("cli, console, approvals, finance") // read-only taps
hri.score(action, actor) → { severity, blastRadius, actorState, drift }
guardian.intervene(when hri > threshold) → hold | confirm | second-eyes
base44.entities → Actor, Action, Intervention, RiskPolicy // system of record
base44.automations → notify, escalate, audit, learn // closed loop
Why teams trust it

Built to be the one thing that can't make it worse.

Read-only or it doesn't ship

Inner Perimeter never holds write access to your production systems. It can pause an action; it can't perform one.

Explainable every time

Every intervention shows its work: the score, the factors, the policy. No black-box blocks your engineers will route around.

Tuned to under-trigger

The cost of a false stop is a 10-second confirm. We bias hard toward silence so the perimeter earns its place.

Pricing

Priced against the incident it prevents.

One stopped irreversible action pays for the year. Start with a scoped pilot on your highest-risk surface.
