1. Dynamic Application Security Testing

This involves looking for vulnerabilities in a web application that an attacker could potentially exploit from the outside. Because this web app pentesting does not require access to the application source code, it can be done more frequently and faster.

2. Static Application Security Testing

This type of website penetration testing is where you check for the vulnerabilities of a web application from the inside. It involves access to the application’s source code and can provide a snapshot of the web application source code security status in real time.
