OWASP Penetration Testing Providers
Open Worldwide Application Security Project · Published by OWASP Foundation
OWASP is the most widely adopted framework for web application security testing worldwide. The OWASP Testing Guide provides a comprehensive methodology for identifying vulnerabilities in web applications, APIs, and mobile applications through systematic testing procedures. Originally published in 2004 and continuously updated by a global community of security professionals, the OWASP framework covers every aspect of application security from authentication and session management to input validation, cryptography, and business logic testing.
The OWASP Top 10, updated periodically, defines the most critical web application security risks and serves as an industry-standard awareness document referenced by compliance frameworks including PCI DSS, SOC 2, and ISO 27001. The OWASP Application Security Verification Standard (ASVS) provides a basis for testing technical security controls, while the OWASP Mobile Application Security Verification Standard (MASVS) extends this to mobile platforms.
Penetration testing providers that follow OWASP methodology ensure comprehensive coverage of known application-level attack vectors through a structured, repeatable testing process that is transparent and well-documented.
