A secure connection is needed whenever you are connecting over a UK VPN. Without a secure connection, you may not be able to fully access resources and systems located within the United Kingdom. This is because the UK has specific requirements and regulations for access certain data types from outside of the county. Your computer and VPN connection have to make it appear as though you are connecting from within the country anytime you are traveling abroad in order to have full access.
Secure UK VPN Connections by Requiring Two Factor Authentication
One method organizations can use to ensure a secure connection over their UK VPN is to implement two factor authentication. This method requires people connecting to your resources and online systems to not only input their user name and password, but also supply a digital certificate containing the second layer of authentication information. Without the correct certificate, users are not able to be authenticated and access is denied.
