The Verdict
Microsoft Teams is built for enterprise and teams, with a focus on chat and video-meetings. Proton targets privacy advocates and journalists and leads with encrypted-email and vpn.
Both tools come in at similar price points ($4/mo for Microsoft Teams, $3.99/mo for Proton), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Proton offers broader built-in capabilities (7 features vs 6), while Microsoft Teams 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.
