Comparison
ZeroHook vs Proofpoint
Proofpoint secures enterprise email at the gateway — threat detection, DLP, and advanced filtering for organizations with six-figure security budgets. ZeroHook secures email authentication at the DNS layer — SPF, DKIM, DMARC, and compliance evidence for SMBs who cannot justify enterprise SEG contracts.
Best for EU SMBs, SaaS companies, and MSPs who need email authentication monitoring and NIS2/SOC2 DNS evidence — not a full secure email gateway with threat intelligence and sandboxing.
How Proofpoint and ZeroHook differ
Proofpoint is a market leader in enterprise email security. Its Secure Email Gateway (SEG), threat intelligence, and compliance archiving serve Fortune 500 organizations with budgets often exceeding $40,000/year. For large enterprises with dedicated security operations centers, Proofpoint’s depth in phishing detection, URL rewriting, and data loss prevention is difficult to match.
Most SMB compliance audits do not ask whether you run a Proofpoint gateway. They ask whether SPF, DKIM, and DMARC were correctly configured, monitored over time, and documented — the controls NIS2 Article 21, SOC2 CC6.6, and ISO 27001 Annex A.8.16 test for transmission security at the DNS and authentication layer, independent of which SEG filters inbound mail.
ZeroHook automates that DNS-layer evidence: 35 audit checks, continuous monitoring, copy-paste fixes for Cloudflare and M365, and on the Evidence tier ($199/mo), tamper-proof logs and auditor PDFs. It complements — or substitutes for — enterprise tooling when your gap is authentication and compliance proof, not advanced threat sandboxing.
When ZeroHook is the better fit
Choose ZeroHook when your compliance and deliverability problems are DNS and authentication — not missing an enterprise email gateway.
NIS2 or SOC2 asks for DNS transmission security evidence
Auditors want proof that SPF, DKIM, and DMARC were monitored continuously. ZeroHook Evidence tier exports hash-verified audit history, compliance PDFs, and Excel reports mapped to NIS2 and SOC2 controls — at $1,910/yr vs five-figure enterprise stacks.
Mail lands in spam despite enterprise security spend
A Proofpoint gateway does not fix SPF PermError or DMARC misalignment on your outbound marketing domain. ZeroHook diagnoses authentication failures across all sending paths — corporate M365, ESP relay, transactional subdomains — and outputs copy-paste DNS fixes.
SMB budget cannot support enterprise SEG pricing
Proofpoint contracts typically target mid-market and enterprise buyers. ZeroHook Deliverability at $29/mo covers continuous authentication monitoring for teams that need fixes and alerts, not a full threat-intelligence platform.
MSPs need white-label DNS monitoring for clients
Agency tier ($89/mo) and white-label ($15/domain) let MSPs deliver authentication monitoring and client reports under their brand — a service layer Proofpoint partner programs price for enterprise scale, not 10–50 domain portfolios.
When Proofpoint still makes sense
Proofpoint fits enterprise programs where inbound threat detection and DLP are the primary requirement.
Advanced threat protection and sandboxing
If your risk model requires detonating attachments in a sandbox, blocking BEC with ML classifiers, and integrated threat intelligence feeds, Proofpoint’s SEG is purpose-built. ZeroHook does not inspect mail content — it secures authentication and DNS configuration.
Enterprise DLP and archiving compliance
Regulated enterprises needing email archiving, supervision, and DLP policies across tens of thousands of mailboxes need gateway-level controls. ZeroHook addresses DNS authentication evidence, not mailbox-level data governance.
Existing Proofpoint deployment with SOC staffing
Large organizations with dedicated email security teams should keep Proofpoint for inbound threats. Add ZeroHook for outbound authentication monitoring and audit evidence if that slice is not covered by your current stack.
Cost comparison
Proofpoint pricing is quote-based and scales with user count, modules, and support tier. ZeroHook targets the DNS authentication and compliance evidence slice at SMB-accessible pricing — complementary to, not a replacement for, enterprise SEG deployments.

| Feature | ZeroHook | Proofpoint |
|---|---|---|
| Primary focus | Email authentication, DNS security, compliance evidence | Secure email gateway, threat detection, DLP, archiving |
| Layer of protection | DNS and authentication (SPF, DKIM, DMARC, MTA-STS) | Mail flow gateway (inbound/outbound filtering) |
| Copy-paste DNS fixes | Yes — provider-specific remediation records | No — not a DNS configuration tool |
| Threat detection / sandboxing | No — authentication and DNS monitoring only | Yes — core product strength |
| NIS2 / SOC2 DNS evidence | Automated evidence collection, auditor PDFs, portal access | Archiving and DLP modules; different evidence type |
| Typical buyer | SMB IT, compliance leads, MSPs (10–500 domains) | Enterprise security teams (1,000+ mailboxes) |
| Annual cost (benchmark) | $1,910/yr (Evidence tier) | $40,000+/yr (typical mid-market SEG) |
Adding ZeroHook for DNS authentication (with or without Proofpoint)
- 1
List every domain that sends mail — corporate, marketing, transactional, and client subdomains. SEG coverage does not automatically mean authentication passes.
- 2
Run ZeroHook free scan on each domain; document baseline health scores and authentication failures before your audit window.
- 3
Apply copy-paste DNS fixes for SPF, DKIM, and DMARC; re-scan to confirm. This is independent of your SEG configuration.
- 4
Enable Evidence tier 60+ days before audit if assessors need continuous monitoring history and auditor portal access.
Common questions
Can ZeroHook replace Proofpoint?+
No. Proofpoint is an email security gateway for threat detection and DLP. ZeroHook monitors and fixes DNS authentication configuration. They solve different problems — many enterprises use both.
We have Proofpoint but mail still goes to spam. Why?+
Inbound SEG filtering does not fix outbound SPF, DKIM, or DMARC failures. Gmail and Microsoft evaluate authentication on sending domains independently of your gateway vendor. ZeroHook diagnoses and fixes those DNS-layer issues.
Does Proofpoint satisfy NIS2 email security requirements?+
NIS2 Article 21 expects documented technical measures for network and information systems, including transmission security. A SEG alone does not prove SPF/DKIM/DMARC were correctly configured and monitored — ZeroHook produces that DNS-specific evidence.
Which ZeroHook tier should a compliance team choose?+
Choose Evidence ($199/mo) for NIS2 or SOC2 workflows: 50 domains, 365-day tamper-proof logs, auditor PDFs, and Excel export. Deliverability ($29/mo) suits teams focused on inbox placement without full evidence packs.
Is ZeroHook relevant if we use Microsoft Defender for Office 365?+
Yes. M365 security features and Proofpoint address different layers than DNS authentication. ZeroHook ensures your SPF, DKIM, and DMARC records are correct and monitored — the controls external receivers evaluate before inbox placement.
Can MSPs offer ZeroHook alongside enterprise SEG clients?+
Yes. MSPs use ZeroHook Agency and white-label tiers to monitor client authentication posture and deliver branded reports — a managed service SEG vendors do not provide at SMB price points.
