The short version

  • Only Google Cloud Platform has a free tier, so it costs nothing to try first.
  • Each has a real cost: Google Cloud Platform the $300 Free Trial credit expires 90 days from signup, whichever comes first with spending it; 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: Google Cloud Platform covers Compute Engine, 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.

Google Cloud Platform

  • The $300 Free Trial credit expires 90 days from signup, whichever comes first with spending it
  • Free Tier Compute Engine is limited to one non-preemptible e2-micro instance per month and only in the us-west1, us-central1 or us-east1 regions
  • Free Tier Compute Engine includes only 30 GB-months of standard persistent disk and 1 GB of outbound North America data transfer per month
  • Free Tier Cloud Storage covers 5 GB-months of regional storage in US regions only, 5,000 Class A and 50,000 Class B operations per month
  • Free Tier outbound data transfer allowances exclude destinations in China and Australia
  • Compute Engine resources are governed by allocation quotas that require a quota increase request to exceed

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

Google Cloud Platform: What is Google Cloud Platform's pricing model?

Google Cloud uses usage-based pay-as-you-go pricing with options for committed use discounts at 1-year or 3-year terms, which can reduce costs by 25-70%. Pricing varies by region, service, and usage volume.

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.

Google Cloud Platform: Does Google Cloud offer a free tier?

Yes, Google Cloud offers an always-free tier with generous free allowances for development, plus $300 in free credits for new customers during their first 90 days.

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.

Google Cloud Platform: How do committed use discounts work?

Users can commit to 1-year or 3-year usage of specific services to receive discounts of 25-70% compared to on-demand pricing. These discounts apply to compute, storage, and other services.

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.

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.
