Pricing

ProtonVPN's paid plans run $4.49–$9.99/mo, pricier than AdGuard VPN's $2.99–$11.99/mo range – but its free tier is the standout: genuinely unlimited data, not AdGuard's 3GB/month cap.

Features, jurisdiction & audits

ProtonVPN is open-source, publishes independent security audits (by Securitum), and – like AdGuard VPN – is based in an EU-adjacent, privacy-favorable jurisdiction (Switzerland). This is the audit gap AdGuard VPN doesn't yet close.

Which should you choose?

If a provably audited no-logs policy and open-source code are non-negotiable, ProtonVPN is the stronger privacy pick. AdGuard VPN's advantage is its built-in ad/tracker blocking and lower price on longer plans.
