A Cisco virtual private network (VPN) uses advanced tunneling
protocols and encryption techniques to protect the end-to-end
private network over the Internet. A VPN essentially makes part
of the public Internet a private network. The VPN allows users
to connect to a corporate office from anywhere he or she can get
Internet access. A VPN also allows secure access with suppliers
and partnering companies from the Internet. The best reason for
having a VPN is its advanced security features. Cisco has a wide
range of VPN-enabled routers, access concentrators, and
firewalls. The two main Cisco VPN groups are: remote access VPNs
and site-to-site VPNs.

More About VPNs
Today's Virtual Private Networks (VPNs) securely connect remote
users to the business network. Secure VPNs have high-levels of
security by way of encryption and authentication technologies.
When VPNs are site-to-site, traffic is encrypted with IP Security
(IPsec) and Multiprotocol Label Switching (MPLS) and Frame Relay
through data encryption and authentication. When VPNs have remote-access,
Secure Sockets Layer (SSL) VPN, IPsec, or both are used (depending on deployment requirements).
