I always find it interesting that people want to refer to the outcome of applying a complex and nuanced term like "security" to some product as being "well known".
Aah too true, ethereal propaganda at its finest.
They work well on management types as well:
"All your competitors use X because it's known to be more secure"
"You need to use Y because it is proven to be more efficient"
"Recent research has shown that Z has the best uptime"
For less technically savvy managers, consider replacing "secure" with "virus-proof", "efficient" with "virus-resistant" and "uptime" with "virus protection"

Ok, Tim don't take this the wrong way but I love you.
I'm well familiar with that situation. Some of the research these "whitepapers" quote ranges from funny to insulting. I remember once someone gave me some vendor rag that said "Model XXX rackmounted server is 15% more power efficient than the average for it's class". I wish I could have been the math teacher for the writer of that article...so I could fail him.
It gets worse. I used to get a bunch of security trades (because as soon as that word gets attached to your title people want to start selling you stuff). I read a comparison of Email filter appliances and it ranked them on about four pieces of criteria....except how they filtered email.
I canceled all my subscriptions.
