Application Security

Secure architecture, threat modelling, design review, code and pipeline assessment — from identifying weaknesses to implementing effective controls with the teams that own and ship the application.

Why it matters

The most effective security decisions happen before a weakness reaches production.

Application risk is rarely just a code problem. Architecture, trust boundaries, identity, dependencies, build pipelines and deployment choices all shape what an attacker can ultimately reach.

We work with engineering teams from design through delivery — modelling threats, reviewing architecture and code, strengthening pipelines and helping implement controls that remain practical in production.

Engineers reviewing an application architecture with a security advisor
Scope

Architecture, code and delivery — secured as one system.

Architecture & threat modelling

Trust boundaries, identities, data flows and abuse cases reviewed before design decisions become expensive to change.

Code & dependency security

Manual and tool-assisted review focused on exploitable weaknesses, unsafe patterns and third-party dependency risk.

Pipeline & supply chain

CI/CD hardening, secrets management, build integrity and software supply-chain controls from commit to deployment.

Controls & secure SDLC

Security requirements translated into standards, guardrails and controls that engineering teams can actually operate.

How we work

From architecture to working controls.

Scaled to the environment — from a focused assessment to an ongoing application security program.

01

Understand the system

Architecture, assets, identities, trust boundaries and abuse cases mapped around how the application actually works.

02

Assess the controls

Design, source code, dependencies and delivery pipelines assessed against realistic attack paths.

03

Engineer the improvements

Controls and remediation worked through with the engineers responsible for implementing and operating them.

04

Make it sustainable

Standards, guardrails and tuned tooling embedded into the lifecycle so the next release inherits the improvement.

In detail

What you receive.

Deliverables

  • Architecture review, threat model and abuse case catalogue
  • Code and architecture review findings, prioritised by exploitability
  • CI/CD, secrets and software supply-chain hardening plan
  • Controls & secure SDLC definition with gates and ownership
  • Practical remediation support with engineering teams

Ideal for

  • Product teams shipping continuously into a regulated market
  • Organisations modernising an application security program that has become tool-led
  • Engineering groups scaling faster than their security practice
  • Teams introducing new architectures, cloud services or sensitive integrations
The outcome

Security decisions translated into controls that engineering teams understand, can operate and can carry forward into future releases.
