SecuMailer

What SecuMailer does

SecuMailer is a Netherlands-based SaaS provider of secure and legally compliant email, headquartered in Lelystad and operating since 2017. It serves regulated organisations — Dutch municipalities, government agencies, healthcare providers (including GGD-GHOR and JA-Groep), legal firms, financial advisory and accounting practices, housing corporations, and other professional services — that must communicate privacy-sensitive information by email without violating GDPR, NTA 7516, NEN 7510, BIO, eIDAS, and (from 2025) DORA. The platform operates as a transparent mail relay between the customer's existing email infrastructure (Outlook, Gmail, Microsoft 365, on-premise Exchange, Cisco ESA) and recipient mailboxes, applying AES-256 encryption, two-factor authentication, and customer-defined mail flow policies in the background, with no portal, plug-in, or user-side action required. Notable technical components include a proprietary SmartTLS engine that validates recipient servers' TLS versions and certificates, REST/SMTP/GraphQL APIs with OpenAPI 3.0.1 documentation, serverless AWS Lambda email processing, eIDAS qualified registered email (qREMS), and a Data Haven hybrid solution offering customer-controlled, on-premise or Dutch private-cloud storage of email content with KBKDF-managed keys.

Core offering

SecuMailer operates a SaaS secure email platform that sits as a mail relay between customer email servers and recipient mailboxes, automatically applying AES-256 encryption, policy-based rules, and SMS-based 2FA authentication without requiring plug-ins, portals, or behaviour change from senders. The platform is sold primarily as a per-user subscription targeting regulated European organisations, with add-on modules for large file transfer, eIDAS qualified registered email, hybrid data storage, and DLP.

Product overview

SecuMailer is a unified SaaS secure email platform built around a core SecuMailer product with multiple add-on modules. The core platform handles automatic encryption and policy-based email security without portals or plug-ins, integrating directly with customers' existing email environments (Outlook, Gmail, Microsoft 365). Additional modules extend functionality: SecuFiler handles large files up to 5TB; eIDAS Registered Mail provides legally binding proof of delivery; Data Haven enables hybrid storage within customer-controlled environments; Data Loss Prevention prevents unauthorized data leaks; Smart Encryption performs recipient server validation; and Private Dutch Cloud ensures EU data sovereignty. Pricing is modular—customers pay per user/month for the core platform plus optional fees for SMS, eIDAS messages, SecuFiler, and add-ons.

Expansion highlights5 records

Direct peers

• Zivver: Amsterdam-based secure email and file transfer platform targeting Dutch healthcare, government and legal sectors. Direct competitor with overlapping NTA 7516 certification and interoperability agreement with SecuMailer, competing on similar regulated-vertical customers in the same home market.
• Enovation (ZorgMail): Dutch secure-communications provider with strong footprint in healthcare via the ZorgMail network. Has an explicit interoperability agreement with SecuMailer and is the most entrenched incumbent in the NTA 7516 healthcare secure-mail category.
• Virtru: US-based email encryption and data-protection platform offering end-to-end encryption, key management, and DLP for enterprises and government. Direct peer in secure email encryption with similar SaaS delivery and policy-based encryption model.
• Paubox: US secure email provider focused on HIPAA-compliant encryption for healthcare organizations, delivered as background-running secure mail without portals. Closely comparable UX philosophy (no plug-ins, no portals) to SecuMailer's security-by-default model.
• Tuta (Tutanota): End-to-end encrypted email and calendar service headquartered in Germany, marketed heavily on GDPR compliance and EU data sovereignty. Smaller and consumer-leaning, but competes for the same privacy-first, EU-hosted positioning.
• Proton (Proton Mail): Swiss-based end-to-end encrypted email provider with strong EU/EEA sovereignty positioning and a growing enterprise/business tier. Comparable in regulated privacy-first marketing and EU data-residency branding.

Broad incumbents

• Proofpoint: Large enterprise cybersecurity vendor offering email security, DLP, archiving, and compliance as part of a broader portfolio. Competes with SecuMailer in regulated buyers that already run Proofpoint but typically as one SKU within a much larger stack.
• Mimecast: Global email security, archiving, and compliance SaaS incumbent. Overlaps with SecuMailer's secure-mail and compliance positioning but bundles email security into a broader suite targeted at larger enterprise customers.
• Microsoft (Purview / Exchange Online): Bundles secure email, encryption, DLP, and compliance capabilities inside Microsoft 365 / Purview at effectively zero marginal cost. The most credible alternative for buyers willing to accept a productivity-suite-tied solution rather than a specialized vendor.

Emerging players

• SendGuard: Smaller secure email gateway provider offering encryption and policy-based delivery for SMB and mid-market customers. Partial overlap with SecuMailer's email-security-by-policy model, focused on a different scale of buyer.
