Penetration testing, also called pen testing, describes processes, tools, and services designed and implemented to simulate attacks and data breaches and find security vulnerabilities. You can run a pentest on a computer system, an entire network, or a web application.

The primary aim of a pentest is to identify vulnerabilities that attackers can exploit. There are various ways through which the identified vulnerabilities can be discovered. You can choose either manual pen tests, executed by a team of white hat hackers, or automated penetration testing, carried out by a software solution. Curious to learn more? Let’s dive in!

What are the Benefits of Penetration Testing?

Ideally, software and systems were designed to avoid hazardous security vulnerabilities in the design. A pen test shows how close it came to achieving that goal. Penetration testing can help an organization in these ways:

1. Find weaknesses in systems
2. Determine the robustness of controls
3. Support compliance with data privacy and security regulations (e.g., PCI DSS, HIPAA, GDPR)
4. Provide qualitative and quantitative examples of the current security posture and budget priorities for management
