OWASP Top Ten 2021 Report

The Open Web Application Security Project (OWASP) Top Ten 2021 Report helps keep your web application secure against the latest threats.

  • Since the first edition in 2003, the list of top ten application security risks reflect industry trends, web technologies, and threat landscape.
  • Thanks to the OWASP Top Ten 2021 Report, you can identify the common weaknesses, which can be present in your web application, exploited by malicious attackers.
  • Developers and technical staff can prioritize, understand, and fix security issues because the report provides essential information, such as HTTP request and response, to them.

For further information about the OWASP Top Ten 2021, see What the OWASP Top 10 2021 categories mean for OWASP compliance.

This topic describes the different sections of the OWASP Top Ten 2021 Report. It also explains how to generate and download the OWASP Top Ten 2021 Report in Netsparker Enterprise and Netsparker Standard.

There can be other vulnerabilities and security issues found in your web applications but not listed in the OWASP Top Ten 2021 Report. For the comprehensive security report, generate the Detailed Scan Report.
