Symantec bought Vontu. Never heard of Vontu? They are an established player in the data-leakage security niche. Primarily deployed on networks that fall under the purview of the Gramm-Leach-Bliley Act, Vontu's flagship product works like an IPS, but instead of loading it up with vulnerability signatures, you load it up with keywords and snippets of your confidential data.
For $350M, this is is a gamble for Symantec for a couple of reasons. First, the expansion of the data-leakage market is very much a question-mark. Sure Vontu's poised to dominate if it does blow up, especially with Symantec's Panama Canal of a channel. But Symantec is a desktop client company. They've killed every network device they've ever acquired, and some that they built themselves. Sure Vontu has a desktop client as well, but it's not their leader.
What I find most interesting about this acquisition is that Symantec is known for paying pennies for secondary niche players and trying to pump them on their brand recognition against primary niche players. Their whole product strategy can be summed up as "one brand, one vendor." In this case, they bought one of the best-of-breed players in the niche, if not the top dog. And they paid good money for them, too. Recent acquisitions like Altiris and Revivio were more of the old Symantec trying to find a bargain buy into a new market. So the Vontu purchase leaves me confused. I would've expected Symantec to buy somebody like Tizor and stay away from Vontu and PortAuthority.
By the way, there's an excellent Forrester paper on Symantec's ongoing shopping spree. If you work for a Forrester subscriber, or own a lot of Symantec stock, it's worth reading. (I am the former and, at not the latter, for what that's worth.) If you're keeping track, Symantec has acquired no fewer than 31 companies since 2000.
Also, Vontu co-founder (and recent multimillionaire!) Joseph Ansanelli testified before a House subcommittee about combating identity fraud. (PDF Link) Another interesting read, but when you contrast this with the recent ID theft study that Bruce Schneier blogged about today, you have to wonder if there's a decent sales line for these products beyond GLBA compliance.
