Cisco bought IronPort this morning.
As a general comment, I applaud this decision. It makes sense for them to move into email and web security (not known to many is that IronPort recently launched a web filtering appliance).
IronPort’s products are outstanding, and the company is itself the nes plus ultra of professionalism. Now the issue that Cisco will need to decide upon is whether they want to move downmarket: IronPort has extraordinary presence in the Global 2000 with their high-end systems, but other vendors (notably Barracuda) have a stronghold in the SMB channel.
At any rate, this is a good move by Cisco.
