Penetration testing, also known as pen testing, is a simulated cyber attack that is conducted on a computer system to identify vulnerabilities and weaknesses that could be exploited by hackers. The goal of a pen test is to help organizations identify security weaknesses before they can be exploited by malicious actors. However, the cost of penetration testing can vary widely depending on a number of factors, such as the scope of the test, the complexity of the system being tested, and the experience of the security professionals conducting the test.
