Initially created as a response to the difficulty of implementing earlier versions of IPsec VPNs, SSL VPNs have become increasingly common over the past few years. Because they were built to be easier to implement, they were thought of as easier to manage than IPsec, which led to their growing popularity.
However, IPsec offers many features that SSL doesn’t have, as detailed in the presentation given by Rainer Enders, NCP’s CTO of Americas, in a slidecast for insideHPC. Rainer explored recent trends in remote access technologies and delved into the progression of IPsec and SSL VPNs.
In many ways, SSL has been evolving to become more like IPsec because businesses have demanded many of the features that are traditionally in IPsec VPNs, such as access to the entire corporate network rather than just applications. As a result, the formerly “client-less” option has required a bigger footprint to add those features.
At the same time, IPsec has become much easier to use. NCP’s IPsec VPN client suite features a firewall and Internet connection that are integrated into a single interface. Users only need to click on a button once to securely connect or disconnect. Everything else is automated, and users never need to worry. So, it’s no longer true that IPsec is more difficult to connect to than SSL.
Although SSL and IPsec are becoming more alike in many ways, each has unique features that are useful for different business needs. NCP develops VPN functionality based on both protocols, and we are constantly working to make them easier for IT administrators to manage and for users to enjoy mobility’s benefits.
