What do you like best?
Fireeye is amazingly fast at vm analysis. Their product does a great job at detecting, with efficiently, all kinds of malware, CnC activity and other malicious content. The central manager is also well designed. Being able to monitor, update, and few all appliances in your organization, as well as notate and acknowledge alerts is powerful
What do you dislike?
Price and scalability. Their product line is very expensive to purchase and maintain. The other substantial challenge we have right now is scalability. Many of our global sites have greatly increased their internet pipes, and the nx appliance at that location isn't designed for that bandwidth. At this point, your only option is to purchase another box. This is a substantial challenge...again, because of cost.
What business problems are you solving with the product? What benefits have you realized?
Primary business problem is securing our egress point of contact with the internet. FE has been able to stop a large volume of C2 traffic as well as other malware.
