Security - Cisco AnyConnect Secure Mobility Client

Security - Cisco VPN client software


The Cisco VPN Client is a software-based application developed by Cisco. The VPN client is designed to allow remote users to establish a secure [Virtual Private Network (VPN)](/vpn) connection over the internet with a Cisco VPN gateway device, typically a Cisco [ASA](/asa) firewall.

The Cisco VPN Client was commonly used in corporate environments to allow employees to securely access their corporate network from remote locations. It uses the [Internet Protocol Security (IPSec)](/ipsec) protocol to establish secure connections.

However, Cisco VPN Client has been considered a legacy product for several years. It is no longer being updated or actively supported by Cisco. The company's current VPN solution is the [Cisco AnyConnect Secure Mobility Client](/security-cisco-anyconnect-secure-mobility-client), which provides a wider set of features and is compatible with a larger range of operating systems and security protocols.
