If I've already got Postini what value add would installing GroupShield for Exchange provide???
More specifically internal emails within the co. (10K employees) are not scanned but all nodes on the network should have McAfee VSE On-Access Scanning enabled and current (about 95% compliant). So if a threat attempted to propogate wouldn't OAS on the individual machines catch it? Why have emails scanned on exchange? It seems duplicitous...
Any thoughts would be welcome!
Thanks,
