What Smartlockr does

Smartlockr B.V. is a Netherlands-based (Amsterdam) B2B SaaS company that sells an AI-powered secure email and file-sharing platform designed to prevent data breaches caused by human error. The platform combines zero-knowledge end-to-end encryption, an SMTP relay service for background protection, and add-ins for Outlook, Gmail, and Yahoo. AI/ML capabilities automatically detect sensitive content in email bodies and apply appropriate encryption or policy controls, with the vendor claiming 75%+ accuracy versus keyword-based content policies. Adjacent features include email and file recall, an upload portal for secure inbound files, multi-factor authentication, and Single Sign-On integration with Azure AD and ADFS.

The product is sold primarily through a direct enterprise sales motion with on-site implementation support for large customers, supplemented by a partner/reseller channel that includes a strategic collaboration with Workspace 365. Customers span Dutch and Swedish verticals — healthcare (Flevoziekenhuis, Korion, Novadic-Kentron, Cedrah, Partou), municipalities (Gemeente Alkmaar, Meppel, Zeist), financial services (Alfa Accountants, VKG), legal (Verstraten en Partners), and housing corporations (Parteon, Woonplaats, Sirjon). Pricing is quote-based, structured as an annual subscription per licensed user with a "pay only for the features you use" modular model, plus optional professional services for training and custom implementation. The company was previously known as AttachingIT before a 2018 rebrand and is privately held, having raised funding in 2019, 2021, and 2023 from Value Creation Capital, NextGen Ventures, and Round2 Capital Partners.

Core offering

Smartlockr provides an AI-powered secure email and file sharing platform that prevents data breaches caused by human error. The platform combines zero-knowledge end-to-end encryption, automatic sensitive content detection, and email/file recall capabilities, delivered via Outlook plugin, web add-in, or background SMTP relay. It targets regulated organizations that need to protect sensitive communications while complying with standards such as NTA 7516, AVG/GDPR, and WvGGZ.

Product overview

Smartlockr is a secure email and file sharing platform built around AI-powered data loss prevention and zero-knowledge end-to-end encryption. The core Smartlockr platform is a unified product that combines human-centered email security with automatic content detection — users can work with a background/relay mode (invisible security) or an active Outlook/plugin mode (user-controlled), or combine both. The product portfolio includes the core Smartlockr platform itself, the Web Add-in for browser-based email clients (Outlook Web Access, Gmail), the Admin Portal for centralized IT management and logging, the Secure Communication Portal for recipient access, the Upload Request/Upload Portal for receiving files securely, configurable Content Policy/content filters for automatic or manual data detection, and the SMTP Relay Service for server-level email routing. The platform integrates with Microsoft Outlook, Gmail, Yahoo Mail, Azure AD, and ADFS, and is certified against ISO 27001, NEN 7510, and NTA 7516 standards.

Broad incumbents

• Mimecast: Mimecast is a large established email security and archiving vendor offering DLP, encryption, and threat protection. It competes with Smartlockr at the high end of the regulated-enterprise market but covers a much broader feature set.
• Hornetsecurity: Hornetsecurity is a European email cloud security provider offering spam filtering, DLP, encryption, and compliance. Its European base and broader portfolio make it a regional broad incumbent versus Smartlockr's focused pitch.
• Proofpoint: Proofpoint is a leading enterprise cybersecurity company with mature email DLP, encryption, and compliance products. It is the dominant broad incumbent against which niche vendors like Smartlockr differentiate on ease of use and zero-knowledge architecture.
• Microsoft Purview / Microsoft 365 Compliance: Microsoft Purview (within Microsoft 365) bundles DLP, encryption, and compliance into the standard Outlook stack. As the underlying platform Smartlockr plugs into, it is the most important incumbent to displace and represents both an opportunity (native gaps) and a threat (commoditization).

Direct peers

• Egress (KnowBe4): Egress provides intelligent email security with AI-driven DLP and encryption, including shared mailboxes, file sharing, and threat detection. It targets healthcare, government, and regulated industries with a human-layer security narrative closely mirroring Smartlockr's positioning.
• Zivver: Amsterdam-based secure communications platform offering email encryption and large file transfer for healthcare, government, and legal verticals. Zivver is the closest direct competitor to Smartlockr in the Dutch secure-email category, with overlapping customer segments and a similar zero-knowledge encryption pitch.
• SendSafely: SendSafely offers end-to-end encrypted email and file transfer with portal-based recipient access, similar to Smartlockr's Secure Communication Portal and Upload Portal. Both compete in regulated industries needing secure file exchange.
• Virtru: Virtru delivers end-to-end email and file encryption with Google Workspace and Microsoft 365 integrations, focusing on regulated industries that need zero-trust data protection. The product scope and target buyer overlap materially with Smartlockr.
• Tessian (Fortra): Tessian builds AI-powered email security that prevents data loss from human error and detects advanced phishing. Its human-layer, behavior-based DLP approach is the closest analog to Smartlockr's AI content detection and human-error positioning.
• Paubox: Paubox provides HIPAA-compliant secure email delivered through a Microsoft Outlook add-in, with automated encryption for outbound mail. Its healthcare-vertical focus and plug-in delivery model overlap materially with Smartlockr's healthcare offering.
