Mozilla VPN and ProtonVPN represent two notably different approaches to consumer privacy tools, and their overall scores reflect that difference clearly. Mozilla VPN earns an overall score of 40%, while ProtonVPN scores 89%, making this one of the more lopsided comparisons in the VPN market. That said, examining the individual category scores reveals a more nuanced picture of where each service succeeds and where it falls short.
Both providers score identically in the ethics category, each earning a perfect 100%. This signals that both organizations operate with transparent, user-focused values at their core. Mozilla VPN also performs well in streaming, matching ProtonVPN with a perfect 100% score, and it edges ahead in nothing else of comparable note. Its speed score of 75% is respectable, though it falls slightly below ProtonVPN's 80%.
Where Mozilla VPN struggles significantly is in areas that many privacy-conscious users consider essential. Its privacy audit score sits at just 15%, and its customer support score is 0%, meaning users who encounter technical issues may find themselves without reliable assistance. The application score of 20% also suggests the software experience leaves considerable room for improvement. Its GUI score of 40% further points to a less polished user interface compared to its competitor.
ProtonVPN, based in Switzerland, benefits from one of the world's most favorable legal jurisdictions for privacy. Its privacy audit score of 100% reflects independently verified practices, and its customer support score of 100% means users can expect reliable help when needed. ProtonVPN also supports WireGuard, a modern and efficient tunneling protocol, alongside split tunneling and a bug bounty program, which demonstrates a commitment to ongoing security research and transparency. Its GUI score of 100% and application score of 80% indicate a well-developed and accessible user experience.
Both services include a kill switch and support for P2P torrenting, which are practical features for users who prioritize connection security and file sharing. Mozilla VPN is based in the United States, a jurisdiction that carries more legal uncertainty for privacy compared to Switzerland, which may be a relevant consideration for users particularly concerned about data exposure.
In summary, ProtonVPN leads across nearly every measured category, offering stronger privacy credentials, better application quality, and more comprehensive support. Mozilla VPN may appeal to users who already trust the Mozilla brand or who prioritize streaming performance, but the gap in core privacy and usability metrics is substantial.
