You have a good chance of IPS affecting your scanning. For instance, it could block SYN half-open packets, which are 
widely used by vulnerability and port scanners.
You need to check you IPS log to see if it blocks packets coming from your scanner.

Subject: Vulnerability Scanning - Prioritising Remediation

I'm currently documenting how to prioritise remediation efforts from my last vulnerability scan.  As my assets have all 
had information risk assessments conducted, I can easily calculate my CVSS score using the CVSS2 calculator.

I then started thinking about compensating controls in my network where I could possibly lower the priority of the 
remediation.  For example the SSH vulnerability priority may be lowered as there is a signature for prevention on my 
IPS.

The question I can not answer is if my IPS has prevention for such a signature, and I'm running a vulnerability scan 
through that IPS, will my IPS block those packets, with the end result being my VA scan does not detect the 
vulnerability?

Thanks.
