VPN Protocols
There are no limitations regarding the use of VPN protocols.
Shimo supports every major VPN protocol that is currently available: The widely used CiscoVPN, the very secure OpenVPN and all standard-compliant IPSec connections. It also handles Point-to-Point Tunneling (PPTP VPN) and Layer 2 Tunneling (L2TP) protocols. Even Cisco’s new Secure Socket Layer (SSL) protocol AnyConnect is supported by Shimo – the most flexible VPN client for Mac. Shimo also enables you to establish encrypted Secure Shell (SSH) connections including port forwarding for secure web browsing.
There is no other VPN client for Mac which supports this variety of available protocols. If you want to have the all-in-one solution for your secure connections, Shimo is technology of choice. This feature is not only helpful, if you have to handle different types of connections, but rather in cases where your system administrator upgrades or changes the used protocol. With Shimo you are always prepared and ready to go.
Shimo does not support PPTP/L2TP on macOS Catalina due to Apple's enforced security requirements.
In general, don’t upgrade a system until all prerequisites are available. If you’re not sure or just in general, perform a test install and a scratch upgrade. As for this app, check for an update, and then contact Cisco Support if not.
Roll in your prior-to-the-upgrade backups and revert, if there’s no AnyConnect update available.
Having run a web search for Cisco AnyConnect Catalina finds the following support notice:
Cisco AnyConnect Users With macOS 10.15 Might Not Be Able To Establish VPN Connection or Might Receive System Pop-up Messages—Software Upgrade Recommended
Cisco AnyConnect and HostScan require updated releases for compatibility with the upcoming macOS Catalina release (10.15). Beginning with macOS Catalina release (10.15), the operating system will no longer support the executing of 32-bit binaries. Additionally, applications must be cryptographically notarized in order to be installed by the operating system. Cisco AnyConnect 4.8.00175 is the first version that officially supports operation on macOS Catalina and contains no 32-bit code.
Which implies there’s a bug or mis-configuration here. If there’s no newer AnyConnect version and no other support notes, contact Cisco Support. This is a Cisco app, so Cisco Support will have a better position to identify and address any app issues.
