It looks like you have a typo in the Socket Filter Bundle Identifier. It should be com.cisco.anyconnect.macos.acsock. Try changing that and see if makes any difference.

@RBlount I fixed that but it still wont move past "activated waiting for user". I copy pasted Socket Filter Designated Requirement so that should be right.

This is related, but not exactly the same thing. Are you aware if there is a way to either delete the socket filter on install, or use jamf to remove it completely? We are running into an issue where the Anyconnect socket filter in causing issues when it is installed on systems with SEP installed. The socket filter on Anyconnect doesn't like having the SEP socket filter installed too. We have to have the SEP one per organization ISO, and manually removing the Anyconnect one on each mac is proving troublesome.

only difference I can see is that in our identifier its: com.cisco.anyconnect.macos.acsock
Attaching our info.

there is a difference, filter Order is set.

Is the System Extension in a different config profile? Probably need both to get it approved without user interaction.

we're experiencing similar issues. I went through and changed per the suggestions above, but still doesn't seem to want to enable it automatically (still prompting the user).

I also went through this KB article and at the bottom is the text for their premade mobileconfig, which I put into jamf and it still prompting.

Deleting these worked for me. AnyConnect still works fine.

/Library/LaunchAgents/com.cisco.anyconnect.vpnagent.plist
/Library/LaunchDaemons/com.cisco.anyconnect.gui.plist
/Library/LaunchAgents/com.cisco.anyconnect.notification.plist

You might be able to get away with deleting just the last one, though.

EDIT: Confirmed that this is the only one you need to delete:

/Library/LaunchAgents/com.cisco.anyconnect.notification.plist

Anyone having any luck with a silent uninstall?

"/opt/cisco/anyconnect/bin/anyconnect_uninstall.sh"
"/opt/cisco/anyconnect/bin/dart_uninstall.sh"

Is throwing a user-prompt to remove content filter.

This was added o install script to prevent RunAtLoad (startup) >

rm -f /Library/LaunchAgents/com.cisco.anyconnect.gui.plist
echo "Prevent RunAtLoad"

I know this is a bit late but this might be useful to some: I got rid of the Secure socket message during Uninstall:
In my use case I needed the AnyConnect app to be force quit before, you can comment that line out if not needed.

@markdmatthews  did you ever find out how to resolve this? I'm getting the same popup when using the uninstall.sh

I have a configuration profile configured for the content filter

did you ever find out how to resolve this? I'm getting the same popup when using the uninstall.sh

Currently Apple Requires a user interaction to remove system extensions like Cisco’s Socket Filter. To remove System extension via CLI Apple requires SIP to be disabled. According to the terminal binary this is temporary, but its been temporarily 4 years without any comments about this changing any time soon. Just another management item Apple is forcing user I interaction on unfortunately.

@AJPinto 

   I see many people say "web content filter" are they referring to the "content filter" payload?

from what i'm reading here CISCO  section 3.2 brings up information that looks like this has to be configured in the system extension --> RemovableSystemExtensions property   in order to remove it .  So when the uninstall.sh is run then maybe this property being set will stop that popup.

Is there an equivalent elegant way to stop the popup notification for Cisco Secure Client v5.1.x.x?  The command

no longer works as that file is no longer there to delete.  I do have an alternative method.

  Deleting the notification app works, but it seems so brute-forced.
