Please share with us the security software, office VPN and firewall that your IT department installed on your office notebook for the IT and cyber security experts to advise properly.
You can click on the up arrow at the extreme right of the task bar and do a screen-grab first and post the screen-grab of the software that are running in the background for the Cyber security experts here to evaluate.
Typically, if you are connected to your company’s VPN, the VPN gateway and portal will capture all your internet activities if your company VPN routes all internet traffic through the VPN tunnel and out of the company’s internet routers.
If you disconnect from Company VPN to do your personal web browsing, then you will be tracked by cloud-based cyber security tools installed on your computer like Carbon Black, SentinelOne, Mandiant FireEye or even Sophos and TrendMicro.
Most of the time, you can’t disable these tools without local admin access or a token that can only be retrieved or generated by the Cyber-Security admin.
Hope this answer your question. If you are satisfied with my answer, please mark this post as the answer so that admins can close this thread and award points to me.
Thank you.
