Based on my experience, I would give people considering this solution the advice to work with Fortigate. It is a newer technology. It can manage Multi VLANs and you can manage DMZ zones by using an easy end-user GUI interface.  

On a scale from one to ten where one is the worst and ten is the best, I would rate FortiCache overall as an eight-out-of-ten.  

I would recommend this solution. I would rate it a seven out of ten.

I would say you should go for it. Make sure to understand the terms and conditions of the support. 

In the next release, I would like to see better email server hosting. 

I would rate it a seven out of ten.
