Penetration testing, also called “pen testing,” can help with the security of an application (app) by looking for vulnerabilities, or weaknesses, that hackers can exploit. For the slightly older generation, you can compare a pen test with testing the security of your home.

Imagine you want to check how safe your home is from burglars. You hire someone who tries to break in, but in a safe way and with your permission. This person looks for ways someone could get in, such as a poorly locked window or a weak front door. At the end of the test you will receive a report stating what the weak points are and how you can improve them, for example by installing a stronger door or better locks.

A pen test for an app works much the same, but it concerns digital weaknesses. For example, the security expert tries to log in without a password or access sensitive information that should be well protected. If something is found, you will receive advice on how to improve security.

In summary, a pen test helps to ensure that an app is better protected against hackers and other digital threats, so that users are safer and data does not just end up on the street.
