Tenable Nessus Professional is widely praised for several key features that make it a preferred choice for vulnerability management BUT I want to focus my review on why it make sense for you if you have a lot of IP to scan.

Most of the scanners have licenses per IP, so if you have wide ip ranges, licenses fee would be astronomious.

You will need to accomodate the limited reporting and vulnerability management feature of the proffessional version. Review collected by and hosted on G2.com.

Nessus Professional need some good process OR automation to get the most of it as you dont have any 'quality of life' feature like dashboard, tracking and limited automation. Review collected by and hosted on G2.com.
