The model proposes. The gate authorises.
Sector8 is a deterministic runtime control point for AI agents. Before an agent executes a refund, database query, MCP call, shell command, file operation, or API request, Sector8 decides whether the action is allowed.
Same action, same policy, same decision. Fail-closed at the gate.

The Gap
Your agent is both the proposer and the approver
An agent decides what to do and then does it. Nothing sits between the decision and the action, which is like an insider approving their own expense claims.
Prompt instructions do not close that gap. “Never refund more than £50” in a system prompt is still a suggestion to a model that can be argued with, injected into, or simply mistaken.
Actions, not answers
A wrong sentence is embarrassing. A wrong tool call can move money, delete records, modify code, expose data, or trigger a production workflow. The blast radius changed when agents got hands.
Guardrails that guess
Classifiers and LLM judges are probabilistic. They inherit many of the same failure modes as the agent they police, and a miss is silent.
No answer for the auditor
“Why did the agent do that?” needs a record of what was evaluated, which policy version decided, and why the action was allowed or denied. A log line saying it happened is not enough.
How it works
One decision point, three guarantees
1. Propose
The agent emits a tool call. Before execution, the proposed action is sent to Sector8 as structured input: tool, parameters, context, identity, and policy scope.
2. Decide
A deterministic policy engine evaluates the action against policy-as-code and returns ALLOW or DENY. No model judges another model. If the gate cannot evaluate safely, the action does not run.
3. Prove
Every decision returns an audit record: decision trace ID, evidence hash of what was evaluated, and policy version that decided. Allows are recorded, not just denials.
We do not try to govern what the model thinks. We govern what it is allowed to do.
Determinism
A control you can test
Fire the same attack at the same policy a thousand times and you get the same DENY a thousand times, each with its own decision record. Run that test against a probabilistic guardrail and see what comes back.
If it is not reproducible, it is not a control.
Shadow mode
Start with enforcement off
Deploy Sector8 alongside your existing agents in shadow-sm mode. It evaluates every proposed action and logs what it would have denied, with the gap between your intended policy and actual agent behaviour. Nothing is blocked.
Two weeks later, you have a report of every action your agents attempted that violated your own policy. Then you choose which rules to enforce.
No disruption
Run Sector8 with enforcement off while your current agents continue operating.
Real evidence
See the actions Sector8 would have allowed, denied, or routed for review using your own policy.
Clear enforcement path
Move from observation to enforcement only when the policy and evidence are ready.
Who it is for
Built for high-consequence agent workflows
Sector8 is built for teams putting AI agents into regulated or high-consequence workflows: fintech, insurance, healthcare, SaaS, retail, and any organisation whose agents touch customer data, money movement, source code, production systems, or enterprise tools.
Claude Code and developer agents
Control file writes, shell commands, repository access, MCP tools, and sensitive paths before execution.
Customer-facing agents
Control refunds, CRM updates, customer record access, support workflows, and bulk data exports.
Internal copilots
Control access to enterprise systems, internal data, knowledge bases, HR tools, finance systems, and APIs.
MCP and tool-using agents
Authorise MCP calls, tool invocations, and chained actions before they reach downstream systems.
