This joint solution will provide mobile workers with highly secure access to their corporate resources anytime, anywhere. 

“Bundled with movianVPN, the Sony Ericsson P800 will redefine wireless communications for the mobile worker, allowing users to securely access corporate information as if they were in the office,” said Ian McKinnon, President and CEO of Certicom. “Built on the open Symbian OS, the Sony Ericsson P800 offers a powerful solution that allows enterprise users to take mobile communications to the next frontier.
