NextZen Security · Secure AI engineering

Build, contain and deploy enterprise AI safely.

NextZen Security pairs Forward Deployed Engineering teams with a containment engine for AI deployments: code-level permission boundaries and secure agentic workflows, implemented directly inside your repositories. The engine is being productized from controls proven in client engagements.

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 delivery and security testing

Forward deployed engineering and product leadership that gets AI features and agents into production, with threat modelling and adversarial testing on what you build.

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

    Deploy NextZen control modules and verification tests inside your repositories, adapted to your environment, and test expected behaviour and abuse cases.

  4. 04

    Review and hand over

    Deliver reviewed code, the deployed control modules, automated verification tests, 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?+

The deployed control modules and automated verification tests keep running in your environment, alongside the reviewed code, architecture decisions and handover documentation defined in your scope. A team walkthrough covers how to maintain and run them.

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 protection handled?+

Engineering access, deployment changes and testing boundaries are agreed before work begins. After the initial sprint, the deployed control modules and verification tests remain active in your environment. A continuous verification software tier — automated threat modelling updates, tool-boundary testing and telemetry for your security and compliance teams — is in development and offered to early clients as it matures.

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.
