Application Security Testing
Applications are where most breaches start. Our application security testing goes far beyond automated scanners — every engagement is a manual, exploit-driven assessment that chains vulnerabilities the way a real attacker would, then proves impact with reproducible evidence.
Web Application Penetration Testing
Manual web application penetration testing against the OWASP Top 10 and business-logic flaws. Exploit-driven testing with reproducible PoCs and clear fixes.

./open →What application security testing covers
Our application services span the full modern stack. Web application penetration testing assesses your apps against the OWASP Top 10 and beyond. API penetration testing targets REST, GraphQL and gRPC against the OWASP API Security Top 10, including broken object-level authorization (BOLA) and mass assignment. Mobile application penetration testing covers iOS and Android with static and dynamic analysis. GraphQL security testing dives deep into resolver-level authorization and query-depth abuse. And secure code review finds vulnerabilities at the source, tracing untrusted data from input to sink. Together they give you defence in depth across every layer where your application meets untrusted input.
Why application security matters
The majority of reported breaches trace back to an application weakness — a missing authorization check, an injectable parameter or a business-logic flaw an attacker abused. These issues rarely show up in a vulnerability scan because they require a human to understand your application's intent. A thorough application penetration test gives you an honest picture of exploitable risk, defensible evidence for customers and regulators, and a prioritized path to remediation. It also supports compliance programs such as PCI DSS, SOC 2 and ISO 27001 that mandate regular application testing.
How to choose the right service
If you have a web app with logins and sensitive data, start with a web application penetration test. If your product is API-first or powers integrations, prioritize API penetration testing. Shipping a mobile app? Combine mobile testing with backend API testing, since much of the real risk lives server-side. If you want to catch entire classes of bugs at the root — or a black-box test hinted at deeper logic flaws — add a secure code review. Not sure where to start?
