The Verdict

Proton is built for privacy advocates and journalists, with a focus on encrypted-email and vpn. WhatsApp Business targets small businesses and ecommerce and leads with business-profiles and product-catalogs.

Pricing is close: WhatsApp Business starts at $0/mo versus $3.99/mo for Proton — not a deciding factor on its own.

Both offer free plans, so you can test each with your real workflow before committing to a subscription.

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.
