AI software assurance and production engineering

From an AI-built app to software your business can trust.

We review code, access, data and deployment for internal tools, business-critical systems and SaaS products. When we find risk, we can help fix it.

From prototype to production

Faster software creation does not remove responsibility for how it runs or what it can access.

The turning point

A prototype became part of the business.

It starts as a tool for one person. Then come more users, customer data and access to production systems. That is the time to review trust boundaries.

Others now rely on it

The tool has users and affects daily operations.

It handles important data

Customer or employee data, or a production database, is now involved.

Access is too broad

The app or agent can do more than its job requires.

Ownership is unclear

No one owns deployments or incident response.

What we review

The code is only part of the system.

Automated scans find some problems. The review also covers data flows, business logic and deployment decisions.

After the audit

Keep the code that works. Fix what should not be left to chance.

The audit report comes before a remediation proposal. Every recommendation has a reason. Your team, ours or another supplier can make the changes. We then retest the findings.

How we rescue architecture

Who this is for

  • Internal tools supporting important operations
  • SaaS applications before customer release
  • Systems built quickly with Claude Code, Codex or other agents
  • People and teams who want to put AI-assisted code into production responsibly
  • Existing apps without clear access control, tests or deployment procedures

Before we work together

Questions before an audit

Do you only review AI-generated code?

No. We also audit conventionally written applications and systems developed by several teams. We examine architecture, data flows, access controls, testing and deployment. The origin of the code helps explain the development process, but it does not replace a review of the running system.

Will you rewrite our application?

Usually not. We identify parts that work and areas that need repair or refactoring. The report separates launch blockers from changes that can be planned later, so your team can decide which fixes to implement independently.

Is this a penetration test?

The application audit reviews code, architecture, data access, configuration and production readiness. We do not present it as a penetration test. If specialist security testing is needed, we scope that separately.

Can we keep using Claude Code and Codex?

Yes. We review what agents can access, which data and services they can reach, and how the team checks their changes. You can continue using AI tools while adding code review, tests and access controls suitable for a production system.

Do you need production access?

We agree on the minimum access before starting. A repository, architecture documentation and a test environment are usually enough. If we need to inspect production configuration, we agree on the scope and method of access first.

Will our code be sent to an external AI model?

We do not send client code to external AI services without explicit contractual approval. Before the audit, we agree on how materials are processed, who can access the repository and how data is handled. We can also define which code must not be used with AI tools.

The type of system, its users and your main concern are enough. Do not send passwords, API keys or source code.
