IPsec VPN
IPsec VPN – Quick and easy site to site communication
IPsec leverages powerful encryption algorithms in order to protect your data as it passes over the public internet.
Quick to implement, flexible, and secure, Point to Point IPsec VPN’s represent the simplest, and least intrusive, way to connect two or more remote locations, when scalability and high throughput are not the primary concerns.
IPsec explained
.
What is it?
IPsec is not a protocol in itself, but rather an umbrella term for a suite of protocols that, when combined, secure traffic at the IP layer. The ultimate aim is to simulate the functionality you would get from connecting two remote locations by a single (potentially very long) cable.
How does it work?
A dialogue is initiated between the two ends of the point to point link, they negotiate the initial security settings, and exchange authentication information, either in the form of digital certificate or, more commonly, a pre-shared key. When authentication has been successful a tunnel is established between the routers. Traffic sent over this tunnel is encrypted using one of a number of pre-defined cryptographic algorithms. This makes the contents unreadable to anyone that intercepts the traffic.
