Mazu Networks is the one we want to focus on. Their ability to scale without exponential price increases is what sets their ROI model apart from the rest...

Scaling is only one factor. How about cost of ownership and complexity? Adding a Mazu box, starting at $50,000 dollars, is a whole lot of arm-waving and jumping up and down just to get information that can be had for a fraction of the price and effort using Congruity Inspector. No VC overhead to pass along to the end-user and focused on SMB users, it scales to thousands of concurrent nodes and provides complete end-to-end visibility into all on-line communications. Whether you're a geek and want port level activity or a compliance individual wanting to see who was emailing out the financial reports, Inspector delivers the information without all the fuss, overhead or cost.
