But Miguel Perez, general manager of Santiago, Chile-based reseller Novared SA, said large companies are still better off using best-of-breed products. Suites of commodity security offerings likely make sense only for small and mid-size business because of the lower complexity and cost.

"For big companies, the cost of best-of-breed technologies is not significant compared to what they are risking" by moving away from them, he said. And this won't change until vendors start delivering better management capabilities for dealing with integrated security products, he said.
