Penetration testing has gained a lot of popularity over the past few years. The reason is simple — with the advancement in techniques of developing and using computers, security takes center stage.
A penetration test, also known as Pen Test, is a human-driven investigation of a company’s security. The testing team uses various methods to detect and exploit weaknesses within the company’s network environment.
While organizations are very well aware of the fact that they can’t make each system 100 percent secure, they always try to minimize the weak points within the system. And how do they do that? By conducting penetration tests at regular intervals.
The effectiveness of a penetration test depends on numerous factors. One of the key factors is the knowledge and experience of the tester. If he/she can’t precisely simulate real-world attacks, the test would be less effective.
Another crucial factor is the tools used to conduct tests. With incorrect or outdated tools, the penetration tester may overlook vulnerabilities and errors in the target network or system.
This is why it is very important to hire knowledgeable testers and use the right tool. A good penetration testing tool helps you discover hidden vulnerabilities in the network, server, and web applications.
We have gathered some of the best penetration testing tools that handle comprehensive network security operations in all the environment. They all are powerful enough to identify unknown weaknesses, errors, and malicious scripts that can cause a security breach.
