The Verdict
Proton is built for privacy advocates and journalists, with a focus on encrypted-email and vpn. SpiderOak ONE targets privacy advocates and journalists and leads with zero-knowledge-backup and file-sync.
Pricing is close: Proton starts at $3.99/mo versus $6/mo for SpiderOak ONE — not a deciding factor on its own.
Proton has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. SpiderOak ONE requires a paid subscription from day one.
Proton edges out on user ratings (4.5 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Proton offers broader built-in capabilities (7 features vs 6), while SpiderOak ONE takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for privacy advocates, journalists — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Proton has a slight overall edge — but if true zero-knowledge encryption matters most to you, SpiderOak ONE may still be the right call.
