Modern information loss avoidance (DLP) and also firewall software guidelines not allowing outgoing VPN links are a good starting point, however SSL is extremely challenging to accurately obstruct, as a result of the fact that numerous legit safe web sites utilize SSL. VPN services can also be subscribed to for concealing a host’s exterior IP. For example, a site or solution may only be allowed the UK, yet if someone in the USA links to a UK VPN server and also uses it to surf to the website, it would certainly appear they remained in the UK.
