The wonderful thing about Rsam is that it is incredibly adaptive, it can change with the flow of new trends in InfoSec without missing a beat. It allows engineers, users, and management types to adjust to new threats while maintaining continuity, and demonstrating effectiveness of their teams and providing metrics that continue to warrant their existence as a business unit. 

The scope of your question, in regards to SIRP, suggests that Rsam exists in a bubble, unaware of the other tools and aspects of InfoSec, but in truth, it really does shine when the synergy between those other pieces all comes into alignment and you have a truly detailed but zoomable view of what is actually happening with your assets.

I rate it solidly at nine out of 10. There are things that could be better about it but that is to be expected. A tool that is highly customizable is also susceptible to odd combinations that the vendor may not be able to plan for. The vendor does, however, rapidly respond to those outliers and works diligently to resolve.
