First-generation VPNs, IPsec VPNs, have provided remote user and site-to-site connectivity for more than a decade. However, IPsec VPNs create “all-or-nothing” access to the network and generate significant costs and pain due to VPN client software management.

Second-generation VPNs, SSL VPNs solved IPsec VPN shortcomings by offering increased security and reduced operating costs through zero client software management. However, SSL VPNs have not met the expectations of replacing IPsec VPN products. Every product on the market until now has caused significant performance degradation and loss of productivity when used to replace IPsec VPN products, preventing enterprises to benefit from increased security and lower cost of operation advantages of SSL VPNs.
