The short version

  • Only Keeper has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keeper free tier is severely limited to 10 passwords on a single device; essentially a trial rather than a usable free version; Proofpoint licensing is per user per year with each capability as a separate stock item, so the platform shown in a proof of concept is normally several products, and adding awareness training, data loss prevention or insider threat monitoring later is a fresh negotiation rather than enabling a feature.
  • They diverge on capability: Keeper covers Password management, Proofpoint covers Inline secure email gateway.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keeper

  • Free tier is severely limited to 10 passwords on a single device; essentially a trial rather than a usable free version
  • Personal plan at $1.79/month is promotional pricing; regular price is higher, making budget comparison difficult

Proofpoint

  • Licensing is per user per year with each capability as a separate stock item, so the platform shown in a proof of concept is normally several products, and adding awareness training, data loss prevention or insider threat monitoring later is a fresh negotiation rather than enabling a feature.
  • It sits inline with MX records pointed at it, so any service degradation is a mail outage for the entire organisation, and both migrating on and migrating off are cutovers with queueing, rollback planning and a real risk of message loss.
  • Most customers on Microsoft 365 E5 or Google Workspace Enterprise are already paying for native filtering, so Proofpoint is a second licence layered over a capability the organisation owns, and that comparison is raised by finance at every single renewal.
  • The administration console carries a decade of acquisitions: the classic gateway policy routes and filters do not share a model with the newer module interfaces, rule evaluation is order-sensitive in ways that surprise untrained administrators, and mistakes there silently change what is delivered.
  • Quarantine management is a standing helpdesk workload because legitimate bulk mail, invoices and supplier notifications are held, and unless end-user digests are configured and users are taught to use them, the security team becomes the mail release desk.

Answered from the vendors’ own pages

Keeper: Is there a free version of Keeper?

Keeper offers a free version with very limited functionality: it stores only 10 passwords on a single mobile device with no cross-device sync. A 30-day free trial provides full access to all features.

Source
Proofpoint: Does it replace Microsoft Defender for Office 365?

Functionally it overlaps heavily, and running both means paying twice for filtering. Most Proofpoint customers on Microsoft 365 keep Defender licensed because it is bundled in E5 and use Proofpoint as the inline gateway. Expect to justify that duplication annually.

Keeper: What are Keeper's paid pricing plans?

Keeper Personal starts at $1.79/month (promotional pricing) with annual billing. Keeper Family covers up to 5 users at $3.83/month annually. Both include unlimited password storage, cross-device sync, and 2FA support.

Source
Proofpoint: Who owns Proofpoint?

Thoma Bravo, a private equity firm, which took the company private in 2021. It has continued to acquire since, including Tessian, Normalyze and Hornetsecurity, which is why the portfolio spans so many adjacent categories.

Keeper: What browsers and devices does Keeper support?

Keeper has browser extensions for Chrome, Firefox, Edge, Safari, Brave, and Opera. It also offers native apps for iOS, Android, macOS, Windows, and web access.

Source
Proofpoint: Do I have to change my MX records?

For the gateway, yes. That is what makes it inline and able to block before delivery. Some newer capabilities integrate through the mailbox API instead, but the core protection model is MX-level.

Keeper: Does Keeper support 2FA and passkeys?

Yes, Keeper stores and autofills FIDO2 passkeys and supports multiple 2FA methods including TOTP, SMS, and WebAuthn. Biometric login (fingerprint/face recognition) is also supported.

Source
Proofpoint: Is security awareness training included?

No, it is a separate subscription. It integrates well with the threat data, so training can target the users actually being attacked, but it is a distinct line item on the quote.

Keeper: How secure is Keeper?

Keeper uses zero-knowledge architecture where data is encrypted and decrypted only on your device. Only you can access your vault, and the company cannot see your passwords or data.

Source
Proofpoint: What does Threat Response Auto-Pull actually do?

It removes messages from mailboxes after delivery when the verdict changes, including copies that users forwarded internally. It is the answer to the case where a link was clean at delivery and weaponised an hour later.
