When compared to other connectivity and security applications the VPN provides numerous benefits, especially with regards to the wireless LAN applications. The two most notable benefits are that of cost effectiveness and network expansion possibilities. It is one of the most secure forms for establishing a connection between company computers at remote locations and within the company.

Previously companies could only obtain the same functionality of the wireless LAN now possible through a VPN, if they were willing to lease lines at extremely high costs.

Network expansion possibilities
