Application security

Web, API, mobile, and AI testing.

Code-assisted testing across web, API, mobile, endpoint, and AI-enabled apps. We test like attackers and work with engineers to land fixes with evidence and prioritisation.

Best for: teams shipping frequently who need developer-ready fixes and proof of exploitability.

What we test

Coverage across application surfaces.

  • Web and API: auth/session, tenancy, business logic, and integration abuse across REST/GraphQL/gRPC.
  • Mobile: on-device storage, runtime protections, auth flows, and backend alignment.
  • Endpoint/thick client: privilege boundaries, update channels, local data handling, and IPC.
  • Secure code review: critical paths, pre-release gates, post-incident validation with tuned tooling.
  • AI/LLM: prompt and tool/agent safety, RAG data handling, and supply chain provenance.
What you get

Evidence-first outputs engineers can use.

  • Developer-ready findings with reproduction steps, artefacts, and code/context notes.
  • Prioritised fixes with impact/likelihood and rollback-safe guidance.
  • Optional mapping to your control framework or policy requirements.
  • Read-out with engineers; fix clinic available for complex items.
  • Targeted verification on high/critical findings included.
Example outcomes

Anonymised results we deliver.

Evidence-led, built for engineering and procurement review.

  • Authorisation bypass in multi-tenant API with exploit proof and ready-to-ship remediation patch.
  • Session fixation in mobile/web SSO resolved; retest confirms fix and telemetry improvements.
  • LLM tool misuse risk mitigated with guardrails, input validation, and logging hygiene.
  • Secure build channel established for Electron client; update path hardened and signed.
  • Control mapping provided for CPS 234/ISO-aligned review without slowing delivery.
