The short version

  • Each has a real cost: Periscope Holdings it is scaled and priced for statewide programmes, so a single city or county typically finds both the implementation effort and the cost out of proportion to its needs.; 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: Periscope Holdings covers Sealed bid solicitation, Proofpoint covers Inline secure email gateway.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Periscope Holdings

  • It is scaled and priced for statewide programmes, so a single city or county typically finds both the implementation effort and the cost out of proportion to its needs.
  • The interface reflects the age and regulatory weight of the platform, and suppliers routinely describe registration and bidding as harder than on newer portals, which can suppress bid response.
  • Ownership has changed twice since 2021, from independent to mdf commerce to KKR, so roadmap and support continuity should be written into the contract rather than assumed.
  • Sibling products inside mdf commerce cover adjacent procurement ground, which means an apparently competitive shortlist may contain two products with the same owner.
  • Statewide implementations are multi year projects with heavy configuration and change management, and the professional services cost commonly exceeds the software over the contract term.

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

Periscope Holdings: Who owns Periscope Holdings?

mdf commerce acquired it in 2021, and mdf commerce was itself acquired by KKR in 2024.

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.

Periscope Holdings: Is it suitable for a single city?

Usually not. It is built and priced for statewide or very large agency programmes.

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.

Periscope Holdings: What is BuySpeed?

The e-procurement platform behind its statewide deployments, covering solicitation through catalogue ordering and reporting.

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.

Periscope Holdings: Can we see what a state paid?

Yes. State procurement awards are public records and typically disclose the full multi year contract value.

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.
