DevSecOps & AppSec
DevSecOps
Build security into the delivery pipeline instead of bolting it on at the end — secure SDLC, CI/CD hardening, IaC scanning, supply-chain controls and guardrails engineers will actually keep.
DevSecOps & AppSec
Application Security Consulting
We assess how your applications actually fail — through design review, threat modelling and hands-on testing — then help you build the AppSec practice that keeps the same classes of defect from coming back.
The problem we solve
Scanners find syntax; attackers find logic. Broken access control, flawed multi-tenancy, weak authorisation on internal APIs and abusable business workflows rarely appear in an automated report, yet they account for a large share of real-world breaches.
Where scanning does help, it is often deployed without ownership. Findings accumulate with no severity model, no SLA and no route to a named team, so the backlog becomes a compliance artefact rather than a work queue.
And security review usually arrives after the architecture is fixed, when the cheapest control — a different design — is no longer available.
Good application security work is specific. A generic report mapped to a generic top-ten list tells you very little; a documented attack path through your own authorisation model, with the fix and the design change that prevents the next one, changes how your team builds software.
Our approach
Adapted to your environment and constraints — but the shape of the work is consistent.
-
Understand the application and its trust boundaries
We start with architecture, data flows, authentication and authorisation model, tenancy design and third-party integrations. The goal is to understand what an attacker would want and which boundary protects it.
-
Threat model where it pays
Structured threat modelling on the systems that matter — new services, significant redesigns, anything handling sensitive data or money. We use STRIDE-style decomposition and abuse cases, and we leave your team able to run the process without us.
-
Test hands-on
Manual application penetration testing against OWASP Top 10 and SANS Top 25 methodologies, combined with authenticated testing, API testing, and review of the specific logic your business depends on. Automated DAST and SAST support the work rather than defining it.
-
Review the code that matters
Targeted secure code review of authentication, authorisation, cryptography, certificate handling, input validation, serialisation and file handling — the areas where a single mistake is worth an exploit chain.
-
Build the practice
Secure SDLC policies and standards, a severity model and remediation SLAs, developer training on the specific defects found in your codebase, and KPIs and KRIs so leadership can see whether AppSec is improving.
Expected outcomes
What changes as a result of the engagement.
- Exploitable design and logic flaws found before an attacker finds them
- Findings that come with a working reproduction and a concrete fix
- Developers who recognise the defect class the next time
- A vulnerability backlog with owners, severities and deadlines
- Documented secure SDLC standards that survive team turnover
- Evidence of application security testing for customers and auditors
- Measurable reduction in recurring defect classes release over release

Book a security consultationCommon questions
Do you do penetration testing, or only advisory work?
Both. Our team includes a background in offensive security — infrastructure and application penetration testing, physical security review and social engineering — alongside programme-level advisory. Most engagements combine a test with the process work needed to stop findings recurring.
What testing methodology do you follow?
Testing is aligned to OWASP guidelines and standards, including the OWASP Top 10 and SANS Top 25, extended with business-logic and abuse-case testing specific to your application.
Will we get a report our enterprise customers can accept?
Yes. Deliverables include a technical report with reproduction steps and a separate executive summary written for business sponsors, senior management and customer security reviewers.
