This presents a security issue, considering that VPN can be used as an encrypted passage to transfer classified information off of a corporate LAN. Modern data loss avoidance (DLP) as well as firewall software rules not allowing outgoing VPN connections are a great beginning point, however SSL is extremely challenging to accurately obstruct, as a result of the truth that lots of legitimate safe and secure sites utilize SSL. VPN services can additionally be registered for for masking a host’s outside IP.
