Omar Aguirre, COO of Optenet, said integrating the functions into a single product could reduce a company's costs by 70%.
Optenet reduces the number of servers needed because central, branch and end-user policies can be set on a single instance, deployed and managed centrally.
Omar Aguirre said enterprise users want to reduce complexity and hardware. They also want greater independence from service providers, Aguirre added.
He said there is a strong trend towards a hybrid model of having core security in-house and outsourcing anti-spam services which can easily be switched to new providers if necessary.
