On the other hand - and hearing about this was a smack-myself-in-the-forehead moment - why not provision IDS/IPS as a service, effectively leasing the infrastructure and offering the rest as a managed service? This is positively brilliant, and AirTight Networks has now done precisely this with their new SpectraGuard Online service, launched today. SpectraGuard Online includes three key capabilities - a vulnerability assessment, which is the detection of rogues and unauthorized traffic, a regulatory compliance module, which simplifies reporting for such elements as SOX and PCI, and an optional vulnerability remediation module, which implements the countermeasures that can be taken to deal with assorted wireless threats. In short, it's everything that AirTight offered before, plus a bit, but at a cost of about $2-$4 a day per building floor covered. This is clearly affordable even if you have a huge number of floors, and removes the last roadblock to everyone having a complete 24x7x365.25 wireless security capability.
