    5 euros a month. Whether you pay for a month, a year, or a decade. They won't even take your account. They give you a code and that's it. You can't even subscribe because they won't store your credit card info. Possibly the single most trustworthy software company in existence and they're absolutely the best at what they do

    Best VPN for privacy and security. Just $5 a month and you don't have to provide an email address or a phone number. You can even pay with cash or Bitcoins.

    I don't like that the Firefox add-on seems to detect uBlock Origin and suggests using its own blocker instead. A trustworthy VPN should keep its nose out of people's stuff. But at least the free tier allows using servers in more countries.

    When you say that it has a free plan, it omits the fact that it only allows you 10GB free a month

    proton is big privacy tech and big privacy tech can turn very easily into big tech so i personally do not trust proton for that reason and windscribe has stated in their blog multible times to not start other projects because that someday will go wrong with user data. and they offer a way better free plan.

    IVPN is one of the best VPN's available, alongside ProtonVPN. Their business model is one of the most transparent of all the VPN providers available. Their employees' names and faces are literally posted on IVPN's official website. In my opinion, IVPN is the most trustworthy VPN company.

    Riseup VPN is the only private vpn I can think of that doesn't limit their free plan. The speeds are good. It has "circumvention bridges." It supports p2p. That said, the windows app can be kind of buggy at times. I know some people are skeptical of them because of the supoena. But given their track record with protecting activist users of their email service, I do trust that they're at least genuine in what they say.
