An open-source security tool called OWASP ZAP (Zed Attack Proxy) is used to identify vulnerabilities in web applications as they are being developed and tested.

OWASP ZAP (Zed Attack Proxy) is an open-source security tool designed for finding vulnerabilities in web applications during the development and testing phases.


  • ZAP offers automated scanners that can identify various vulnerabilities, including SQL injection, cross-site scripting (XSS), and security misconfigurations.
  • ZAP acts as an intercepting proxy, allowing users to monitor and modify web traffic between the browser and the target application. This feature is invaluable for manual testing and identifying security issues.
  • ZAP combines both active and passive scanning techniques. Passive scanning observes traffic for potential vulnerabilities, while active scanning actively sends requests to discover security issues.
  • ZAP includes a spidering tool that navigates through web applications to discover and map out the structure, helping ensure comprehensive coverage during scans.
  • ZAP supports various authentication methods, enabling users to test applications that require login credentials.
  • ZAP provides a rich API, allowing users to automate tasks, integrate ZAP into continuous integration (CI) pipelines, and extend its functionality.


Use the package manager for your system to install OWASP ZAP. For example, on Debian-based systems, you can use:



After installation, you can run ZAP from the terminal by running the command:
