Had a mix-up between two different ASC user topics; yours and another!
Here's part of what went elsewhere, should've been here; may be helpful:
You should see where it may exist in your macOS; if you had Cisco - AnyConnect
which was in your previous product(s) were listed, and work on removal of them.
This appeared in your pastebin report from EtreCheck. And EtreCheck may be able
to remove it; and it's NOT part of the Mac system. And could be removed one way
or another. ~ There's also a manual uninstall process for this 'Cisco - AnyConnect'.

The power issues with your Mac are mostly due to the battery condition; and remove
"Cisco - AnyConnect" items in your Mac system. Also could be other bad actors in OS.
There are two sets of instructions, to see if Cisco folder exists; find Uninstall Anyconnect
double-click to start uninstall process; and follow instructions to uninstall VPN. OR: use
the 'manual uninstall' as shell script from Terminal. See link to "vpn cisco anyconnect."
Note: MIT also has helpful Cisco optional removal instructions beneath 'manual' uninstall

(The fact EtreCheck report mentioned this content in your macOS, it may need removed;
not sure if EreCheck removes items such as this; may have to use uninstall in Cisco itself.)
Sorry for mis-post to another user-question; this was just re-located, should've been here.
Could be useful or maybe not! ~ A day late and a dollar short!
Take care & happy trails!🙂
