We currently have a pair of ASA 5510's and a separate single Ironport S170 for web filtering. My Smartnet is coming due next year on all of them, so I'm wondering should i renew and stay as I am, or should I replace the ASA's with two 5515-X with Firepower services and get rid of the Ironport. Is anyone use the 5515-X firepower services inplace of Ironport, is there any added functionality or any functionality that is lost?
