The representative of this company :

http://www.beyond-ip.com/

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).

Since you are interested in doing Testings..here are some links compliments of my buddy SpannerITWks.
