NEW YORK (CNNMoney.com) -- Security software vendor Symantec unveiled a new strategy and rolled out a set of souped-up products Tuesday as it faces increased competition from Microsoft.

Dubbed "Security 2.0," the strategy is aimed at protecting customers' information and online interactions, rather than just their devices. The Cupertino, Calif.-based company unveiled the new strategy at a press event in New York.

Shares of Symantec have lagged the Nasdaq in the last year.

One of the new products launched was Norton Confidential Online, an application that seeks to increase the security of online banking transactions. The company also introduced updated products for e-mail security and database protection and announced partnerships with Accenture (Charts) and Verisign (Charts)

Online threats have evolved from viruses and worms to more malicious attacks, and combating these threats requires the integration of technology, services and partnerships, Symantec chief executive John Thompson said. "No one company is going to be able to do this by itself," he said.

The latest product rollouts come as top security software vendors are raising concerns over the enhanced security features built in to Windows Vista, the newest version of Microsoft's (Charts) operating system due to ship to businesses next month and to consumers in early 2007.

Security software makers have raised concerns that by embedding security features in its operating system, Microsoft will limit its customers' security choices.

"Microsoft is in a position to win a large market share, especially out of the consumer side because it's free, it's invisible and it's automatic," said Richard Williams, an analyst at ICAP.

Symantec's (Charts) shares have been pressured in the last year, partly due to the threat posed by Microsoft. The stock is down 7 percent over the last year, compared to the 11 percent gain posted by the tech-fueled Nasdaq during the same period. Other security stocks, including McAfee (Charts) and CA (Charts), have posted even more dismal returns in the last 12 months.

But Todd Weller, an analyst from Stifel Nicolaus who rates Symantec a "hold," said it's too early to tell what impact Microsoft may have on the consumer security market. "It'll be important to watch the impact on this market in the next six months," he said.
