OWASP Top 10

The OWASP Top 10 is the most widely referenced awareness document for web application security, published by the Open Web Application Security Project (now the Open Worldwide Application Security Project). First released in 2003 and updated periodically, the current 2021 edition identifies the ten most critical security risks to web applications based on incidence data from hundreds of organizations and input from the security community. The categories include Broken Access Control (A01), Cryptographic Failures (A02), Injection (A03), Insecure Design (A04), Security Misconfiguration (A05), Vulnerable and Outdated Components (A06), Identification and Authentication Failures (A07), Software and Data Integrity Failures (A08), Security Logging and Monitoring Failures (A09), and Server-Side Request Forgery (A10).

Why It Matters

The OWASP Top 10 serves as the baseline vocabulary for web application security across the industry. Regulatory frameworks including PCI DSS explicitly reference OWASP Top 10 in their requirements. Security training programs use it as a curriculum foundation. Penetration testing scopes frequently specify OWASP Top 10 coverage as a minimum requirement. The 2021 update notably elevated Broken Access Control to the number one position, reflecting real-world data showing that access control failures now account for more security incidents than injection vulnerabilities. Understanding and testing against the OWASP Top 10 is table stakes for any organization with a web presence.

For example, a development team building a new API uses the OWASP Top 10 as a security design checklist during architecture review, ensuring that access controls are centralized (A01), secrets are properly managed (A02), inputs are validated and parameterized (A03), and logging captures security-relevant events (A09) before writing a single line of code.

How Revaizor Handles This

Revaizor’s testing methodology incorporates comprehensive OWASP Top 10 coverage as a foundational layer, while going significantly beyond it. Every application tested by Revaizor is systematically evaluated against all ten risk categories, with the platform’s AI agents understanding the nuances within each category that differentiate a thorough assessment from a checkbox exercise. Revaizor maps all findings to OWASP Top 10 categories in its reporting, providing teams with a familiar framework for understanding and prioritizing results. The platform also tests for risks beyond the Top 10, including business logic flaws and application-specific vulnerabilities that require contextual understanding.
