IDC says everybody’s doing it. And they’ll be doing eight times more of it by 2008. “It”, of course, is buying spam solutions. IDC VP Mark Levitt says it’s working.

“The spam problem is being brought under control as a direct result of investments in commercial anti-spam solutions during the past two years.”

As IDC notes, spam filtering equipment is becoming ever smarter… integrating anti-virus and broader content filtering abilities. And the best is yet to come. But the battle never stops. As the black hats unleash new models, the white hats must quickly counter.

The winners? Network owners. As networks harden, they become ever-more secure. That’s good for everyone.
