Sentinel. AI writes the code. You keep control.

AI coding assistants have multiplied how fast your developers ship — and how much unreviewed code lands in front of your reviewers. Sentinel is the quality gate that reviews every pull request, generates the tests, and keeps an audit trail your compliance team can stand behind.

The PR flood is real — and your reviewers are the bottleneck.

Teams that adopt AI coding tools ship more code than their senior engineers can meaningfully review. The result is a quiet governance gap: code reaching production that nobody fully examined, and no defensible answer when an auditor asks how AI-written code is controlled. Sentinel turns that gap into a managed, evidenced process.

Sentinel's expert review panel examining a pull request

What you can do with it

A disciplined review, on every pull request, every time.

A panel of specialist reviewers

Every PR is examined from multiple expert angles at once — security, privacy, architecture, data handling, accessibility and more — each citing the exact lines behind every finding.

A clear go / no-go decision

Findings feed a decision gate governed by your policy, not by mood. The same code and the same rules always produce the same answer.

Tests before merge

Sentinel drafts the automated and manual tests for each change before it lands, so QA starts ahead instead of catching up.

A tamper-evident audit trail

Every review, finding, and decision is recorded in a verifiable chain — evidence you can hand to an auditor, not a claim.

Compliance evidence on demand

Export an evidence pack for SOC 2, ISO 27001, or AI-governance reviews in minutes rather than weeks of screenshot archaeology.

Replay under new rules

Standards tightened? Re-run any past decision under today’s policy and see what would change — governance that learns.

Why teams choose it

  • Keep the speed, lose the risk — your teams keep shipping at AI-assisted pace while every change still gets a rigorous review.
  • 100% review coverage — no PR merges unexamined — including the Friday-afternoon ones.
  • A defensible auditor answer — “how do you control AI-generated code?” stops being an awkward question.
  • Your code never leaves your network — Sentinel deploys inside your perimeter — nothing is sent to a shared cloud service.
  • Fewer false alarms — findings are cross-checked from multiple angles before they reach a human, so developers see signal, not noise.

Who it’s for

For organisations that rolled out AI coding tools faster than their governance.

Engineering leaders

Heads of engineering who need review capacity to scale with AI-assisted output — without burning out their senior people.

Risk, security & compliance

CISOs and governance teams in finance, health, and government who must evidence control over AI-written code.

QA & test teams

Testers who’d rather start from generated test suites and risk registers than from a blank page.

Frequently asked questions

Does Sentinel work with our existing tools?

Yes — it connects to the mainstream code-hosting platforms (GitHub, GitLab, Azure DevOps, Bitbucket) and posts its decision back where your developers already work.

Will it slow our developers down?

The review runs in parallel with your normal workflow and returns in minutes. What it removes is the wait for a human reviewer to find time — and the rework when unreviewed code breaks later.

Where does it run?

Inside your own environment, deployed single-tenant for you. Your source code never leaves your network.
