You can use Penetration Testing tools to find security holes in a network, server, or web application. These tools, also known as Pen Testing security tools, help you identify unknown vulnerabilities in network apps that could cause a security breach.

These tools can protect your network against unauthorized access by hackers. In addition, we will be discussing the best penetration testing tools that provide 360-degree protection against hacking attempts.

Penetration Testing (also known as Pen-Testing) is a hot topic in today’s testing community. It is easy to see why: security has taken center stage with the changes in how computer systems are built and used.

Although companies know they can’t protect every system entirely, they still want to know what security problems they face. This is where Pen-testing can be very useful, thanks to its ethical hacking methods.

What is Penetration Testing?

Testing for penetration is also a kind of security testing conducted to test the safety of the systems (hardware and networks, software, or the information systems environment). This test aims to identify all security weaknesses within an application through analyzing your system’s security using malware and to secure the information from hackers and ensure the security of the application.

It is a kind of non-functional testing that aims to use authorized methods to compromise your system’s security. It is also referred to in Pen Testing or Pen Test. The person who conducts the testing is a penetration tester, also known as an ethical hacker.

4. Netsparker

Netsparker is a web-based application security scanner. It’s an automated, extraordinarily accurate and easy-to-use scanner for web applications. It can be used to automatically detect security vulnerabilities like SQL injection and Cross-Site Scripting (XSS) in websites, web apps, and web-based services. Its Proof-based Scanning technology not only reports security vulnerabilities but also generates the Proof of Concept to confirm that they aren’t false positives. Therefore, there’s no need to waste time checking the vulnerability manually after the scan has been completed.
