A VPN is not invisible, it simply masks the traffic that is being transported so that your employer and ISP can know that there is traffic that can not see it and your employer can then search Ask why you are using unauthorized software Or at least what is the purpose of this VPN. It is unlikely that the ISP will pay attention unless the VPNs are illegal in your country. If you are using a company computer, your business can probably do whatever it wants and one of the things that companies do is to monitor not only network activity but also a computer activity. VPNs are good enough to hide the activity of target websites but they do not hide everything. You have probably enabled cookies in your browser, and in this case it is not difficult to match the activity between enabled VPN sessions and sessions where the VPN was not enabled. Basically, your computer / browser has enough fingerprints that you could trace without too much difficulty if you did not take precautions. The best thing to do is to use a separate browser, cookies are disabled and maybe also use the private / incognito browsing mode that many have now. Some highly secure VPNs are; ExpressVPN NordVPN
Most VPN’s encrypt all data sent and received, If your employer is just monitoring your browsing information then yes, once you securely connect to a VPN all your employer will see is a bunch of encrypted data, if they want to read that data they would have to decrypt it first. (harder then it sounds.)
Likewise your internet service provider (ISP) will not be able to view this data unless they decrypt it.
The websites you visit will see the VPN’s IP address instead of yours so you ARE in effect hidden.
VPNs are pretty good at hiding activity from target websites but also they don’t mask everything. You probably have cookies enabled in your browser and in that case it isn’t hard to match up activity between VPN enabled sessions and sessions where the VPN wasn’t enabled. Basically your computer/browser has sufficient fingerprints that you could be traced without much difficulties if you didn’t take precautions. The best thing to do is used a separate browser, with cookies disabled and perhaps also use the private/incognito browsing mode that many now have.
