The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Proton VPN targets privacy advocates and journalists and leads with no-logs-vpn and kill-switch.
Harbor uses custom enterprise pricing, while Proton VPN starts at $9.99/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Harbor offers broader built-in capabilities (7 features vs 6), while Proton VPN takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
