Application and AI security work scoped to the systems you actually ship.

We review architectures, test applications and APIs, harden cloud and delivery pipelines, and assess the specific risks of AI features such as prompt injection and data leakage — then help your engineers fix what we find.

What we deliver
  • Architecture and threat model review
  • Application and API testing
  • AI system security assessment
  • Cloud and pipeline hardening
  • Remediation support

Where this helps

Security review happens at the end, if at all
Findings arrive a week before launch, when changing an authentication design or a data flow is slow and expensive. The release ships with known issues on a spreadsheet.
An AI feature with access nobody has examined
The assistant can read internal documents and call tools, but no one has tested what happens when a document or a user tells it to ignore its instructions.
A customer questionnaire you cannot answer well
A prospect asks how you manage secrets, access and vulnerabilities. The honest answer is "it depends who set it up," and the deal waits while the team finds out.

What we deliver

01
Architecture and threat model review
A walk-through of data flows, trust boundaries and access, with a prioritized list of risks and specific design changes.
02
Application and API testing
Manual and tool-assisted testing of web applications and APIs for authentication, authorization, injection and business-logic flaws, with reproducible findings.
03
AI system security assessment
Testing of LLM features for prompt injection, data exfiltration through tools or retrieval, excessive permissions and unsafe output handling.
04
Cloud and pipeline hardening
Review and remediation of identity, network exposure, secrets handling, logging and CI/CD permissions in your cloud accounts.
05
Remediation support
Our engineers work with yours to fix findings, add regression tests and retest, rather than leaving a report behind.

How it works

  1. 01

    Scope

    We agree the systems, environments, test windows and rules of engagement in writing, including what is out of bounds.

  2. 02

    Review and model

    Architecture and code are reviewed and the likely attack paths are written down, so testing time goes where the risk is.

  3. 03

    Test

    Testing runs in the agreed environment, with any critical finding reported immediately rather than held for the report.

  4. 04

    Report and fix

    Findings are ranked by exploitability and impact, each with evidence and a recommended fix, and remediation is tracked with your team.

  5. 05

    Retest and embed

    Fixed issues are retested, and the checks that would have caught them are added to your pipeline.

Design decisions we make with you

  • Scope and depth

    A focused test of one critical application is often more useful than a shallow scan of everything. We scope to the systems that hold sensitive data or money.

  • Test environment

    Testing against a production-like staging environment avoids risk to live users; some checks need production and are scheduled with you.

  • AI permissions

    For AI features, the most effective control is usually limiting what the model can read and do, not filtering what it says. We review permissions first.

  • Findings handling

    Reports and evidence are shared only with named contacts and stored under agreed retention. See [trust and security](/company/trust-security) for how we handle client data.

Questions buyers ask

It is technical security work — review, testing and remediation. We do not issue compliance certifications. Our findings and fixes can support your audit evidence, but the audit itself is done by an accredited assessor.

Alongside normal application testing, we try to make the model leak data, exceed its permissions or act on injected instructions — through user input, retrieved documents and tool responses — and check what the surrounding system allows it to do.

Critical issues are reported as soon as they are confirmed. Everything is documented with evidence and a fix, shared only with your named contacts. Read more on our trust and security page.
