Top Penetration Testing Tools for Professionals

Have you been searching for a penetration testing tool that would best serve your security testing requirements for web applications and networks?

Do you want to compare and analyze different penetration testing tools and decide which one(s) would be best suited for your enterprise? Or are you simply curious to know which tools are out there and what their features are?

If yes, then this blog has you covered.

Whether the pen test is conducted for regulatory compliance, security assessment, or strengthening the IT environment’s defense against Cyber Security threats, a combination of the right tools is crucial.

If the penetration tester doesn’t have access to the right tools, chances are vulnerabilities, some critical, may not be detected and hence, reported giving a false sense of security.

Here are 11 penetration testing tools that are very apt at detecting vulnerabilities and accurately simulating cyber attacks.

Let’s have a look at their features and advantages, and platforms they are compatible with.

1. BURP Suite Pro

Burp Suite Pro is one of the most popular, powerful, and advanced penetration testing tools that can help pen testers to fix and exploit vulnerabilities and identify their target’s more subtle blind spots.
