Untangle Ties Storage & Security: Page 3 of 4

"We're comfortable keeping the platforms separate at the moment because of the different needs [of users] and the places that [the technologies] lie in the market," says SonicWall spokeswoman Mary McEvoy, explaining that email security, firewall, and CDP technologies typically require different levels of latency.

SonicWall aims its TZ150 at firms with between five and 20 users. A higher-end model, the TZ180, is targeted at firms with more than 20 users. Pricing for the TZ150 starts at $450, with a $605 list price for the TZ180.

SonicWall remains committed to hardware-based security. "We find that the hardened appliance version is very appealing to a lot of small businesses, because they don't have to fiddle around with user interfaces or software," says McEvoy.

SonicWall is also unlikely to throw its weight behind open source anytime soon. "Our strategy is to have proprietary security," she says. "There can be potential hiccups with open source security and we stand behind the proprietary model."

Analyst Alex Fletcher of Entiva Group believes that Untangle has nonetheless made a shrewd move by going open source. "Untangle has gone after the long tail of the secure content management market," he says. "The SMB sector can typically be priced out of the equation."
