Cisco anyconnect, I know it can work on Linux, and I talked to some collegues using it on Linux on a "don't ask, don't tell" basis, but they had to hack some cert from the Windows version and I'm sure that IT would frown upon this.

I tried installing a second disc in my laptop for Linux to try just this anyway, but I broke the laptop. Yeah this HP laptop has a 2.5" bay and an m.2 connector and it looks like you can use both at the same time, and you can! But if you read in the manual it says you can't because it puts strain on the connector and indeed, the "laptop died" after some days (pretty bad design I'd say). I didn't try anymore after that.

You can grab that cert in a number of ways. IT can do whatever since they have to provide all the data needed to connect anyway.

> you can't because it puts strain on the connector

Well that looks like a feature designed to sell more laptops.
