ProtonVPN (Infrastructure)
Pros
- + Published third-party no-logs audits (Securitum) and open-source client apps — verifiable privacy claims, not slogans
- + Genuinely usable free tier with unlimited data and no credit card requirement
- + Swiss jurisdiction under Proton AG, moving to a non-profit foundation structure since 2024
- + WireGuard/OpenVPN/IKEv2 plus Stealth protocol for networks that block VPN traffic
- + Secure Core routing counters compromised-datacenter risk; NetShield blocks ads, trackers, and malware
- + Paid plans cover 10 devices across 140+ countries with priority support and a 30-day money-back guarantee
Cons
- - $9.99/month rolling price is at the top of the mainstream VPN market; real value requires a 1-2 year prepayment
- - Free tier is one device with random country assignment from ten — no location control
- - Most of the 20,000+ server fleet is rented from third-party network operators rather than Proton-owned hardware
- - No published uptime SLA — the 30-day money-back guarantee is the only contractual commitment
- - Primarily a privacy/access product: no site-to-site networking, static IPs, or deep zero-trust policy on standard plans
Nebula
Pros
- + Free and open source; no vendor sits on your data path
- + Proven at scale — Slack's overlay runs on 50,000+ documented production hosts
- + Modern, non-homegrown crypto: Noise Protocol Framework, Curve25519/P256, AES-256-GCM
- + Certificate-based identity with groups-style firewall rules enforced between peers
- + Direct peer-to-peer tunnels with NAT traversal; lighthouses handle discovery only
Cons
- - You run the PKI: CA key custody, one-year default CA lifetime, certificate signing per node
- - No GUI, no hosted control plane, no SSO in the open-source edition
- - Operationally steeper than WireGuard and much steeper than managed mesh products
- - Overlay IPv6 and mobile client polish lag the desktop experience
- - No support contract or SLA unless you buy the third-party managed offering
