The short version

  • Only Socket has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Socket team plan requires minimum 5-developer commitment, expensive for small teams
  • They diverge on capability: Proofpoint covers Inline secure email gateway, Socket covers Malware detection.
  • 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.

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.

Socket

  • Team plan requires minimum 5-developer commitment, expensive for small teams
  • Business plan $50/dev/month becomes costly for teams exceeding 20 members
  • Enterprise pricing requires custom consultation with no transparent pricing
  • Free plan limited to individual developers without team collaboration
  • Reachability analysis improvement (90% false positive reduction) only on Enterprise

What is Proofpoint best used for?
Proofpoint is most often used for a regulated organisation that needs a filtering layer, dmarc enforcement and archiving with an auditable trail across all three, an organisation that suffered a business email compromise and must show its board a control that stops delivery rather than remediating afterwards, concentrating stronger controls and training on the specific individuals who actually receive targeted attacks rather than applying uniform policy, retracting a phishing message from thousands of mailboxes after the verdict changes, including copies that were forwarded internally. Of those, a regulated organisation that needs a filtering layer, dmarc enforcement and archiving with an auditable trail across all three and an organisation that suffered a business email compromise and must show its board a control that stops delivery rather than remediating afterwards are not what Socket is typically brought in for.

Answered from the vendors’ own pages

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.

Socket: How many zero-day attacks does Socket detect?

Socket detects over 100 zero-day attacks weekly across JavaScript, Python, and Go ecosystems.

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.

Socket: What is precomputed reachability analysis?

Socket's precomputed reachability analysis cuts CVE false positives by 60% automatically on Team plans, and up to 90% on Enterprise plans through function-level analysis.

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.

Socket: Is there a discount for annual billing?

Yes. Socket offers a 20% discount for annual commitments across all subscription tiers.

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.

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.
