I think they offer a reasonably secure portfolio of services for a cost. They don’t accept anonymous crypto like XMR for payment, so like any VPN who has your IP address and a payment history you are trusting them to do what they say they do with what they know about your traffic. In my opinion they offer streamlined and effective obfuscation for people who have a concern with ISP, Stingray, and location based content blocking. Azirevpn can be configured and paid for anonymously if your threat model requires less trust in your VPN provider. You can try both for free and ProtonVPN offers free tiers for long term use as well.
