Standard Corporate Approach
Symantec are pretty much the same, they decided to rebrand MessageLabs this week and change the website branding for spam manager, the format of the spam manager emails they send to users, and informed people with a blog post on their news alerts that most of us didnt have access to.
Cue calls from lots of users and infosec types demanding to know what this phishing/malware/terrorist virus attack was all about.
Symantec's response? "It wasn't a major upgrade, what's the fuss about?".
Would have thought the mass of phone calls you evidently got that stopped us getting through for hours would have clued you in guys?
