| 1.6GPAMozilla VPNWeak | 2.8GPAProton VPNGood | |
|---|---|---|
| Value for money | C$59.88 a year, shown as $4.99 a month, with no intro deal, so two years cost $119.76, about $4.99 a month. That's exactly the middle of what VPNs charge. Monthly is $9.99, and tax comes on top. | CVPN Plus bills $83.76 for the first 24 months, about $3.49 a month over two years, just above the cheaper quarter of VPNs, which tops out at $3.33. It then renews at $83.88 a year, above the middle. Monthly is $9.99, and Proton Unlimited adds Mail, Drive and Pass for $119.88 a year. |
| Free plan and trial | FNothing free: no free plan and no trial. The 30-day refund is only for first-time subscribers who paid on Mozilla's website, and a refund isn't a trial. | BFree for good with no card, no ads and no data limit, which is rare. One person could really live on it. The limits are one device, medium speed, and servers in 10 countries picked for you. |
| Features | CWireGuard on Mullvad's network, ad, tracker and malware blocking, multi-hop, app exclusions and custom DNS. But the listing shows the limits: 5 devices, about 500 servers in 30+ countries, and the Firefox per-site rules work on Windows only. | BSecure Core routing through Switzerland, Iceland or Sweden, the Stealth protocol, NetShield blocking, port forwarding, a kill switch and open-source apps with published audits, on 10 devices with Plus. It covers the whole job. |
| Ease of use | D3.44 from about 500 App Store ratings, the lowest on record among VPNs here and under the 3.8 a C needs. | B4.65 from about 120,000 App Store ratings, just under the 4.7 an A needs. On the free plan there's no card and nothing to set up. |
| Platforms and integrations | BWindows, Mac, Linux, iPhone and Android, plus a Firefox extension. There's no integration list or API beyond Firefox, so it stops at B. | BMac, Windows, Linux, iPhone, Android and a browser extension. There's no integration list or API on record, so it stops at B. |
