SSL VPN Embraced by Large Enterprises

Virtual Private Networks or VPNs allow corporate enterprises to extend access to their internal networks to external employees and partners over standard Internet public networks. The primary reason VPNs came to be was the immensely expensive lease line solutions. An enterprise had to have a physically closed network connection between its partners and remote employees, either through dial-up RAS (Remote Access Server) solutions into the enterprise network, or lease fractional T1 type connections between remote offices and partners.

VPNs are the enabling technology which allows clients (employees) and partners to use standard public Internet ISPs and high-speed lines to access closed private networks. A common misconception is that VPNs are always IPSec protocol solutions. In fact, there are many encryption and security protocols which offer the functionality of a VPN. SSL is one such protocol.

A Multi-Layer Approach to Security

Array employs a defense in-depth approach to security with a multi-layer SSL firewall built on Array’s proprietary SpeedStackTM which is a networking architecture where every single flow (associated stream of packets) is inspected in both directions. Inspection of packets is done at multiple layers of the OSI stack. However, the beauty of the architecture lies in the underlying implementation where no data is ever copied or otherwise moved around, and all duplication of work is eliminated. If a certain piece of work has already been done at a certain layer and the information is required for a subsequent piece of work at a different layer, the information is made available without the second layer needing to repeat the same work.
