As a market grows and matures, it looks for ways to secure its place in the overall market space that it occupies. That certainly is true for SSL VPNs. As this market grows to find its identity in the network access management environment, we see developers adding lots of functionality, as well as converging with other product types. While NAC is struggling with its own identity crisis, SSL VPNs simply are seeking their best deployment options. VPNs and firewalls as combined gateways into the network are nothing new. IPsec, though, usually is the preferred venue for this type of implementation. However, there is a lot of discussion that IPsec is less desirable than SSL. That's really not entirely the case. SSL VPNs have a special strength: low cost (or no cost) client-side implementations that use a standard protocol to communicate with web portals.
