Study: VPN Replacement is Tech Driven

A new study from research firm Infonetics says changes in technology drive much VPN replacement, with replacement cycles running a wide gamut of two to six years.

The <”>Infonetics study, entitled “User Plans for VPN Products and Services,” used interviews with network managers at 250 organizations in five vertical markets: education, federal government, finance, healthcare, and retail.

Though the study found that VPNs are widely adopted, with the total penetration for SSL VPNs for remote access running at 39 percent of the study participants, how long a given VPN product is kept around varies.

According to Infonetics, most of the participants reported retaining their VPN products for two to four years. Education and retail respondents, however, where more attention is paid to cost, said they tend to hold out for four to six years before making a new purchase.

The study also found that the big barrier to adoption among holdouts is security with over a third of the participants naming that as their top concern.

Finally, Infonetics found that 14 percent of the respondents use fully managed VPN services, with no single player dominating the market, which is divided primarily among the regional Bells and IXCs (define).

“VPN and firewall appliances are the most popular devices for deploying VPNs across size groups and verticals, followed by router-based products,” said Jeff Wilson, principal analyst for VPNs and security at Infonetics. “There is some variation by vertical and size, but they are not significant. All VPN/firewall appliances are folding in additional security technologies, and the line between VPN/firewall devices and integrated security appliances is rapidly disappearing.”
