Top 10 vulnerability scanners for hackers and researchers

Top 10 vulnerability scanners for hackers to find flaws, holes and bugs

Hacking is an art of finding bugs and flaws in a perfect software which will allow cyber criminals to exploit it for their own malicious gains. Hackers are mostly able to spot the flaws and bugs on their own but sometimes it is worthwhile to use a automated software to find these bugs and holes. A vulnerability scanner is such a automated software which has specifically been written to find such flaw.

Vulnerability Scanner is a specialised software build with a sole purpose of helping security researchers, hackers, system admins and developers to find faults in a particular software, computer system, network and servers. A hacker or security researcher is complemented in his manual testing of software or computer by using such vulnerability scanner making the hackers assessment efficient.

This article brings out such top 10 vulnerability scanner tools available to help hackers and security researchers in their security testing mission.
