Enhanced security: Penetration testing can help you find and fix potential flaws in your web app, lowering the danger of security breaches.

Verify the effectiveness of the existing security policies and controls

Regulation compliance: Many industries have stringent security requirements that must be met. Penetration testing can assist you in ensuring that your web app satisfies these requirements such as PCI DSS, HIPAA, etc.

Configuration Check: Check the configuration and strength of components exposed to the public including firewalls.

Planning: It includes defining the scope, timeline, and people involved among other things. The organization and the provider of web application penetration testing services must agree on the scope.

Reconnaissance: In this phase, the reconnaissance is done which is important for paving the way for the next phase of testing. This especially includes looking for Open-Source Intelligence (OSINT), or any other information available publicly that can be used against you.

Exploitation: In this phase, the Pentester tries to use the information found in the previous phase to help him/her in finding vulnerabilities and misconfiguration in the web application.

Reporting: After the penetration testing is complete, a full detailed report is generated. This report includes a list of vulnerabilities, an analysis of the finding, proposed remediations, and a conclusion.
