Web Application Security
Testing and hardening custom-built applications and APIs against the vulnerabilities a generic scanner won’t catch.
Who this is for: Businesses running a custom web application or SaaS product, not just a marketing website or WordPress site.
The Problem
Custom web applications carry risks a generic website scanner won’t catch, business-logic flaws, broken authentication, and insecure APIs, that need testing tailored to how the app actually works.
Our Solution
We test and harden custom applications against the OWASP Top 10 and API-specific risks, going beyond what automated scanning alone catches.
What's included
- OWASP Top 10 testing
- Authentication and session security review
- API security testing
- Business-logic flaw testing
- Secure code review (on request)
- Input validation and injection testing
This is distinct from our Website Security service, which covers CMS platforms like WordPress. Custom applications and APIs need testing tailored to their own logic, not a generic platform checklist.
Benefits
- Vulnerabilities specific to your application’s logic, not just generic scan results
- A report developers can actually act on
- Coverage for APIs, not just the front-end
