Executive Summary (This is a document excerpt)

North American and European enterprise IT/network operations executives are investing in emerging IP VPN technologies like MPLS and SSL and are moving away from more established technologies like IPsec. Why? Because newer VPN technologies promise lower operational costs, more reliable connectivity, and traffic prioritization for mission-critical apps. To examine these trends, Forrester recently surveyed landline decision-makers on their plans for four IP VPN technologies: MPLS, site-to-site IPsec, remote-access SSL, and remote-access IPsec. Regardless of the particular IP VPN technology, we discovered that security and reliability topped enterprise lists of important factors to consider while deploying VPNs. We also found that interest is still nascent — but increasing — for deploying IP VPNs as a managed service within the next three years. Enterprises largely prefer to acquire these managed VPN services from network operators/service providers.
