The short version

  • 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.; Zendesk aI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
  • They diverge on capability: Proofpoint covers Inline secure email gateway, Zendesk covers Ticket management.
  • 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.

Zendesk

  • AI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
  • Copilot and Contact Center features available as separate add-ons at £50+/agent/month
  • Advanced routing, workforce engagement, and approval workflows limited to Enterprise tier
  • Highest tier requires sales consultation and custom pricing

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.

Zendesk: What is included in the free trial?

You'll have access to all features on the Zendesk Customer Service Suite Professional plan for 14 days, with Copilot included by default.

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.

Zendesk: How is Zendesk pricing calculated?

Base subscription pricing is determined by your selected plan tier and the number of agent seats needed. Additional costs include usage-based features like App Builder and Voice, plus optional add-ons.

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.

Zendesk: What are the contract terms?

Zendesk subscriptions are month to month, annual, or multi-year. Annual billing typically costs less than monthly payments.

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.

Zendesk: Can I upgrade or downgrade my plan?

Yes, changes may apply immediately or at renewal depending on your subscription terms.

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.
