Tunneling protocols

Thid includes the support of the most important tunnel protocols and applications such as OpenVPN and IPSec. Tunnel protocols are widely used to securely transfer data over the public Internet. Depending on the tunneled application, a tunnel may potentially consume a large amount of bandwidth. While it is virtually impossible to break encryption and analyze the traffic inside the tunnel, the tunnel itself can be detected and managed. Various different scenarios are possible. For example, tunnel traffic can be restricted to dedicated tunnel endpoints within a company to control the transfer of confidential data, or a certain amount of bandwidth may be guaranteed for business-critical VPN traffic.
