Application security is about protecting software from vulnerabilities across the whole SDLC — from the first design discussion through to production monitoring. Most breaches begin at the application layer, which is exactly where I focus the deepest attention.
I combine secure design review, threat modelling, manual code review, and hands-on testing of web, API, and mobile applications against OWASP Top 10 and ASVS. Findings come with reproducible steps, real business impact, and a concrete code-level fix — never a generic scanner dump.
Beyond testing, I help teams build durable capability: secure coding standards for your language stack, reusable authentication and authorization patterns, input-validation and output-encoding libraries, and secure-code training tailored to the bugs your codebase actually produces.
Why it matters
- The application layer is the most common initial access vector
- Design-stage review prevents whole classes of vulnerability
- Developer-ready remediation drastically shortens fix cycles
- Shared secure patterns stop the same bug reappearing across teams
My approach
How the engagement runs
Typical engagement: architecture and threat model review, manual code and API assessment, prioritised remediation plan, secure-coding standards, then developer training and re-test.
