Application Security Testing & Consulting
Protect what matters with Application Security Testing & Consulting
Application security testing is the practice of finding and fixing security weaknesses in software — web apps, mobile apps and APIs — through a combination of manual penetration testing, dynamic testing (DAST), static code analysis (SAST), software composition analysis (SCA) and secure code review. Aesparrow’s application security services cover the whole application security lifecycle, from threat modelling and secure SDLC to OWASP-aligned testing and remediation.
We test against the OWASP Top 10, OWASP ASVS, the OWASP API Security Top 10 and OWASP MASVS, review architecture and code for design flaws, and help engineering teams build security into development with DevSecOps automation — so fewer vulnerabilities reach production in the first place.
