After reviewing various Bitdefender products and finding their capabilities outstanding, I am now focusing on Bitdefender VPN. It is available both as part of the Bitdefender antimalware suite and as a standalone product.
I think Bitdefender should create extensions for Chrome, Firefox, and Microsoft Edge Chromium. This would allow users who only want the extension to use it easily.
When installed, the extension would ask for Bitdefender Central login details. Users without a subscription would get 200 MB of data every 24 hours or access to limited servers, similar to other VPNs like Hotspot Shield, NordVPN etc. Premium subscribers could use the extension with full features, helping those who rely on VPNs.
