Application Security

Threat modelling, secure design review, code and pipeline assessment — conducted with the teams that own the software, in the environment they actually ship from.

Why it matters

A vulnerability found in production cost a hundred times what it cost in design.

Scanning tools find what they were written to find, late, and hand the team a backlog with no priority attached. What they cannot find is the design decision that made the vulnerability possible in the first place.

We work upstream of the scanner: threat models before the build, design reviews before the merge, and a pipeline that fails for the right reasons.

Scope

Security designed into the lifecycle, not bolted on at the end.

Threat modelling and design review

Architectural risk surfaced before it becomes code, with the team that will write it.

Code and dependency review

Manual and tool-assisted review, plus governance of what your dependencies drag in.

Pipeline and supply chain

CI/CD hardening, secrets management and build integrity from commit to deploy.

Secure SDLC

Gates, standards and tooling defined so security stops being a release-day argument.

How we work

Four movements, every time.

Scaled to the environment — from a six-week engagement to a multi-year program.

01

Model the threat

Assets, trust boundaries and abuse cases for the system as designed.

02

Review what exists

Architecture, source and pipeline assessed against that model.

03

Fix with the team

Findings worked through in pull requests, not delivered as a PDF.

04

Make it repeatable

Standards, gates and tuned tooling so the next release inherits the work.

In detail

What you receive.

Deliverables

  • Threat model and abuse case catalogue
  • Code and architecture review findings, prioritised by exploitability
  • CI/CD and supply chain hardening plan
  • Secure SDLC definition with gates and ownership
  • Tooling selection and tuning so the signal-to-noise ratio is usable

Ideal for

  • Product teams shipping continuously into a regulated market
  • Organisations whose scanner output nobody triages any more
  • Engineering groups scaling faster than their security practice
  • Teams preparing an application for customer security review
The outcome

Vulnerabilities prevented at design cost rather than remediated at incident cost — and an engineering team that owns the difference.
