Mark Bakker from Xebia -- a specialized international IT consultancy focusing on Enterprise Java -- published an interesting overview of IBM DataPower Security Gateway and Forum Sentry. Mark writes:
"The Forum sentry has some advantages when you compare it to the IBM Datapower XML Security Gateway XS40. The main difference is that you can do more whith only one appliance. You can replace an IBM Webseal, a virus scanner and an IBM Datapower XS40 with only one device.
My advice is to take this device in considerations where you have to choose for an XML firewall/ hardware ESB."
