  • Reviewed code
  • Evaluation tests
  • Architecture decisions
  • Team handover

Your AI prototype works. Is it ready for production?

Turn deployment concerns into engineering tasks, implemented controls and tests your team can repeat.

From prototype to production

Your prototype is ready, but your team needs help implementing deployment safeguards.

Agents with production access

An agent needs production access, but its permissions have not been reviewed.

Evidence for enterprise buyers

An enterprise customer needs evidence of your AI controls before approving the purchase.

Build security into your AI deployment

Hands-on engineering. Independent security assessment.

Get help building the controls your deployment needs, or test the system you already have. Each engagement has defined responsibilities, deliverables and handover.

What an AI assessment can uncover Illustrative examples—not client results

Agent permissions

An agent executes database commands embedded in retrieved content.

Separate retrieved content from executable instructions; restrict tool permissions.

Integration boundaries

An MCP integration can read files outside its permitted directory.

Constrain file access and test the boundary.

Approval controls

An agent can send external emails without the approval required by policy.

Implement and test the required approval workflow.

Findings, severity and framework mappings depend on evidence and the agreed assessment scope.

AI security, governance and compliance readiness

Secure AI engineering, product direction and testing, supported by governance, vCISO advisory and ISO 27001 readiness.

From deployment brief to team handover.

  1. 01

    Discuss the deployment

    Review your AI system, business objective, engineering constraints and intended access.

  2. 02

    Agree the scope

    Define responsibilities, deliverables, dates and fixed fee in writing before work begins.

  3. 03

    Build and test

    Implement agreed integrations and controls with your team, and test expected behaviour and abuse cases.

  4. 04

    Review and hand over

    Deliver reviewed code, test results, documented decisions and a team walkthrough.

AI delivery aligned with your business and customer requirements.

Before we work together.

Can you work with our existing engineering team?+

Yes. Engineers work alongside your team in the agreed repositories and environments, with responsibilities and access boundaries defined before work starts.

What remains with our team after the engagement?+

Your scope defines the reviewed code, evaluation tests, architecture decisions and handover documentation you receive. A team walkthrough covers how to maintain and run the agreed controls and tests.

How is the engagement scoped?+

The written fixed-fee proposal defines responsibilities, deliverables and dates. Changes are agreed in writing before additional work begins.

How are deployment changes and ongoing support agreed?+

Engineering access, deployment changes and testing boundaries are agreed before work begins. Ongoing support is separately scoped, with responsibilities and availability stated in writing.

How is our data handled?+

Evidence is held under NDA, encrypted at rest and in transit, restricted to the named engagement team and destroyed on the agreed schedule. Repository and environment access are defined in scope; client evidence is never used to train any model.

Who delivers the work?+

Your proposal names the accountable team, relevant expertise and review responsibilities. The engagement combines agreed scope and dates, senior review, specialist delivery where needed, evidence handling and handover.

What stands between your AI prototype and production?

Thirty minutes, no obligation. Written scope and fixed-fee proposal within one business day of your scoping call.
