The Verdict
Palo Alto Networks is built for large enterprises and security operations centers, with a focus on next-gen-firewall and cloud-security. Proton targets privacy advocates and journalists and leads with encrypted-email and vpn.
Palo Alto Networks uses custom enterprise pricing, while Proton starts at $3.99/mo — a tangible advantage for teams with a fixed budget.
Proton has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Palo Alto Networks requires a paid subscription from day one.
