Detecting security vulnerabilities is an extremely important task in the testing process. This in turn can be used to uncover security gaps in the system. Penetration testing is one of the others in this process. This step is crucial to keep your important data safe from the attackers.

In this article, we will briefly cover penetration testing and mainly focus on the companies that offer pen testing service providers

What is penetration test?

Penetration test or pen test refers to the simulated cyber attack that is carried out to exploit the system at a specific point in time in order to identify the exploitable vulnerabilities that are related to system security.          OR

A penetration test, colloquially known as a pen test, pentest or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system this is not to be confused with a vulnerability assessment

  1. Once such a vulnerability is found, it is used to exploit the system and gain access to the presented data.
  2. This type of testing falls under ethical hacking and the person doing penetration testing is known as an ethical hacker.
  3. Pen tests are done to find out which problems are difficult to spot when manually analyzing the system.
  4. The state of a system can be exploited if multiple users are allowed using a system with fewer security controls.
