* the VPN is yours, and only yours -- not shared with thousands of other users
* VPN detection is becoming a problem, and Fortressa is harder to detect as a VPN (unlike other providers)
* uses stronger, more trusted protocols than OpenVPN and others commonly used by most providers
* no software to install, so no apps are necessary
The VPN service itself is not limited to Mac/iOS in any way. The configuration steps on Android, Linux Desktop, and Windows are a bit more involved, so I simply haven't had time to properly document those steps. Thank you for reminding me that I need to add that to the FAQ, which is here: https://fortressa.com/faq/
