Symantec (Quote) and McAfee (Quote), in their quests to compete for dollars in the market for security technology, are both using the assets they gleaned from acquisitions in key product releases at the RSA Conference 2007 in San Francisco today.

Symantec, whose CEO John Thompson will give a keynote speech at the show tomorrow, has issued new network access control products that dictate who has access to what data on a corporate network.

The company has upgraded its Symantec Network Access Control (SNAC) 5.1 software to include agentless NAC enforcement, Mac OS X agent support and an integrated 802.1X supplicant.

The software runs on the Symantec's Enforcer appliance, which the company purchased when it bought Sygate in 2005, a machine that helps ensure business networks, branch offices and mobile employees comply with security policy when accessing networks from desktops, laptops or handheld computers.

Rich Langston, senior product manager at Symantec, said offering Mac support will give customers more choices with which to protect their corporate assets.

SNAC will be available Feb. 7, 2007, directly and through the network of Symantec's channel partners, and worldwide in mid-to-late March 2007.

Symantec, which recently bid to buy Altiris to boost its IT management holdings, expects to compete with Cisco Systems (Quote), Juniper Networks (Quote), Extreme Networks and several other vendors in the NAC space.

Microsoft is also expected to come out strong with its NAC vision, which it calls Network Access Protection (NAP), when the Windows Server appears later in 2007.

McAfee meanwhile is no less focused on preventing data from getting into the wrong hands.

The software maker today took the assets from its acquisition of Onigma last year and delivered the McAfee Data Loss Prevention (DLP) Host.

DLP Host, as the name suggests, is host-based, so the agent sits like a security guard on desktops or laptops to stop the leak of confidential data, which happens both through malicious and unintentional mishaps.

Vimal Solanki, senior director of product marketing at McAfee, said the DLP Host prevents data from leaving computers through e-mail, instant messaging, printed documents, USB drives and CD-ROMs.

"We are all data leakers," Solanki said. "When we transmit data, we put it at risk, or when we print something and forget to pick it up, or copy something onto a USB drive and lose it in an airline seat pocket."

Careless copying or transmission of data aren't the only ways data gets compromised; sometimes disgruntled employees or perpetrators are the culprits, copying data to USBs and e-mailing them from a Web e-mail account to competitors.

Protection against such instances, he argued, is something that today's security gateways can't reliably provide from their positions at the edge of a network.
