What does Lockheed's StarVision do and what are some comparable products on the market?

I consult for a client who has Lockheed's StarVision as part of their advanced persistent threats tool set. For various political and business reasons, I have not been able to get a close-up look of the StarVision tool. I tried to "google" StarVision and came up very little, no data sheet or specification of any kind. What are some comparable products on the market I can look at to get a better understanding of StarVision?
