The representative of this company :

http://www.beyondip.com/pages/Support/support.htm

has stated the device of this company has no impact on any network device during its vulnerabilities scan, though if it is peak time.

Any insight ?

If we want to do comparison between it and Nessus

The device as representative mentioned it is a special dell box compatible with the specific Linux OS designed for this purpose (vulnerabilities scan).
