The short version
- Only Bitwarden has a free tier, so it costs nothing to try first.
- Each has a real cost: Bitwarden the integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month; Microsoft Defender the overview page names Business, Business Premium and Enterprise tiers but publishes no per-seat figure on the page itself, routing every plan to a separate pricing page instead

Bitwarden
- The integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month

- File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan
- Two-step login accepts up to 10 hardware security keys per account
- The Families plan is capped at 6 people, so a seventh member means moving to a Teams subscription at $4 per user per month
Microsoft Defender
- The overview page names Business, Business Premium and Enterprise tiers but publishes no per-seat figure on the page itself, routing every plan to a separate pricing page instead
- Full family and business protection requires a Microsoft 365 Family, Personal or Premium subscription rather than being included with the free built-in Windows version
