No further product updates were released after July 30, 2012, and support ceased on July 29, 2014.{{Cite web|url=https://www.cisco.com/c/en/us/products/collateral/security/vpn-client/end_of_life_c51-680819.html|title = Cisco Secure Products and Solutions}} The Support page with documentation links was taken down on July 30, 2016, replaced with an Obsolete Status Notification.{{Cite web|url=https://www.cisco.com/c/en/us/support/web/obsolete/security-vpn-client.html|title = Cisco-VPN-client}}
It was succeeded by Cisco AnyConnect Secure Mobility Client.
Availability and compatibility
The software is not free but is often installed on university and business computers in accordance with a site-license. As with most corporate licenses, administrators are allowed to freely distribute the software to users within their network.
The open-source [https://www.unix-ag.uni-kl.de/~massar/vpnc/ vpnc client] can connect to most VPNs supported by the official client.
VPN Client 4.9.01.0230 beta added support for Mac OS X 10.6.[https://www.cisco.com/web/software/282364316/35919/4.9.1.0230-beta-rel-notes.txt Release Notes for VPN Client, Release 4.9.01.0230 Beta for Mac OS X] Stable version 4.9.01.0180 appears to lack that support; 4.9.00.0050 explicitly did not support versions of Mac OS X later than 10.5.[https://www.cisco.com/en/US/docs/security/vpn_client/cisco_vpn_client/vpn_client49/release/notes/49client.pdf Release Notes for VPN Client, Release 4.9.00.0050 for Mac OS X, Revised: May 21, 2010, OL-11179-04]
VPN Client 5.0.07.0290 added support for 64-bit versions of Windows Vista and Windows 7.[https://www.cisco.com/en/US/docs/security/vpn_client/cisco_vpn_client/vpn_client5007/release/notes/vpnclient5007.html#wp84047 Release Notes for Cisco VPN Client, Release 5.0.07.0290]
Security
The client uses profile configuration files (.pcf) that store VPN passwords either hashed with type 7, or stored as plaintext. A vulnerability has been identified,{{cite web|url=https://www.cisco.com/en/US/tech/tk583/tk372/technologies_security_notice09186a0080215981.html|title=Cisco Security Notice: Cisco IPsec VPN Implementation Group Password Usage Vulnerability}} and those passwords can easily be decoded using software or online services.{{cite web|url=http://www.unix-ag.uni-kl.de/~massar/bin/cisco-decode|title=Cisco Systems VPN Client Group Password Decoder}} To work around these issues, network administrators are advised to use the Mutual Group Authentication feature, or use unique passwords (that aren't related to other important network passwords).
