In computer networking, OpenConnect - an open-source software application - implements virtual private network (VPN) techniques for setting up secure point-to-point connections. It started as a client for Cisco's AnyConnect SSL VPN, which is supported by several Cisco routers, but as of 2013 it includes a server[2] and can offer a full VPN solution.


OpenConnect uses AnyConnect's SSL protocol,[3] implemented within an open-source project unaffiliated with Cisco. AnyConnect VPNs utilize TLS and DTLS to encrypt and authenticate the encapsulated VPN traffic.[4]

ISBN 9781587142888. Retrieved 2013-06-13. "Cisco AnyConnect is a Cisco implementation of the thick client. Because the SSL VPN network extension runs on top of the SSL protocol, it is simpler to manage and has greater robustness with different network topologies such as firewalls and Network Address Translation (NAT) than the higher security of IPsec."
