AnyConnect Day 0 Support for Windows 10 and OSX El Capitan

Best practices to get AnyConnect support on Day-1 of Windows 10, and what to do BEFORE you upgrade.

There is this sort of living legend at Cisco whose name is Pete Davis. Everyone who deals with security knows who he is because, frankly, he's awesome! The guy has forgotten more about remote-access VPN than most of us will ever know, and he's a total geek - which is the ultimate compliment from a guy like me.

Pete came to Cisco via the acquisition of Altiga, Cisco's former VPN 3000 series concentrator, the EZ VPN technology, and the classic Cisco IPSEC VPN client. He is also one of the original guys to come up with the AnyConnect concept for a light-weight client, using SSL VPN, being modular, pulling configurations from the policy server (ASA / ISE), etc.  

In addition to all the VPN knowledge, Pete has pretty much owned AnyConnect since its release and continues to be the world's most passionate advocate for the widely deployed endpoint software client, and is arguably the single-most-responsive Product Manager at Cisco, one of the big reasons why he's become a legend.

With someone of Pete's caliber driving an already stellar team, the AnyConnect team is always on-point with their Day-0 support for new operating systems, testing them while they are in preview mode, filing the bugs with the OS vendor, and being ready for the OSes to become generally available. 

Therefore, it is cool to publicly show that AnyConnect is ready for both Windows 10 and Apple's El Capitan Operating Systems ahead of schedule. However, there are some caveats that I'd like to point out.

AnyConnect: Windows 10 compatibility update

AnyConnect 4.1MR4 (4.1.04011) and 3.1MR10 (3.1.10010) will both be available beginning 7/27/15.

These two releases will officially support Windows 10. To receive support, customers must be running the official release of Windows 10, which is scheduled to become available on 7/29/15.

Caveats & Important notes for Windows 10: For customers upgrading from a prior version of Windows, I.e.: Windows 7, Windows 8, Windows 8.1:

  • Please ensure you either uninstall or upgrade AnyConnect prior to upgrading to Windows 10.
  • If you are using the Network Access Manager module, this capability must be uninstalled prior to upgrading the Windows system to Windows 10. The great news is that NAM is fully supported on Windows 10, it just needs to be installed after the OS is already there.

AnyConnect: Mac OS X El Capitan pre-release information

An installation issue with AnyConnect on OS X El Capitan has been resolved in 4.1MR4.

There is still an open issue with untrusted certificate validation which has been reported to Apple as an OS regression. Please note that pre-release OS support is not provided by the Cisco TAC. Customers can send any additional issues to El Capitan support will not be provided in AnyConnect 3.x as new OS support ends July 2015.
