Smartlockr
Smartlockr is an Amsterdam-based secure email and file-sharing platform that adds encryption and human-error safeguards to outbound email to prevent data leaks.

Smartlockr sells a secure email and large-file-transfer platform built around a specific, well-documented failure mode: employees sending sensitive information to the wrong recipient, attaching the wrong file, or forgetting to encrypt a message that should have been protected. The platform layers encryption, recipient-verification prompts, and policy-based data-loss-prevention checks onto existing email clients (Outlook/Gmail) so that outbound messages get the right protection without requiring end users to change how they send email day to day.
Founded in 2013 and headquartered in Amsterdam, Netherlands, Smartlockr has grown to a lean team of roughly 15-22 employees while reporting over 500 customer organizations, concentrated among healthcare providers, government agencies, and private companies in the Benelux and Nordic regions. The company has raised multiple funding rounds from Dutch investors, including NextGen Ventures 2 and the Security of Things Fund (Value Creation Capital) in 2021, and an additional round involving Round2 Capital in February 2023 to fund international expansion.
Smartlockr’s category—secure email/DLP for outbound communications—is well established, with competitors ranging from large data-protection suites to point solutions like Egress and Zivver. Smartlockr’s differentiation is a people-centric framing: rather than only blocking risky sends outright, it nudges users at the point of sending and treats human error as the primary threat model, which is a reasonable response to the well-documented statistic that misdirected email is a leading cause of reported data breaches in regulated industries like healthcare.
Innovation Matrix Assessment
Smartlockr's product scope (encrypted email, recipient verification, DLP policy checks) has expanded incrementally over a decade rather than through frequent major releases; no independent product-roadmap evidence beyond the company's own blog posts about funding-fueled feature investment was found.
A lean ~15-22 person team supporting 500+ customer organizations, including named sectors like healthcare and government across Benelux and the Nordics, indicates efficient operational execution for its size, per Silicon Canals and the company's own reporting.
Smartlockr has closed at least two funding events (2021 with NextGen Ventures 2/Value Creation Capital, and February 2023 with Round2 Capital) aimed at international expansion, which is real but modest momentum for a twelve-year-old company still in the 11-50 employee range.
Secure email and outbound DLP is a mature category with established competitors (Egress, Zivver, and larger data-protection suites); Smartlockr's people-centric, nudge-based approach is a reasonable UX framing rather than a new security architecture.
No independent breach-prevention study or third-party audit of Smartlockr specifically was found; the claim of preventing data breaches from misdirected email rests on the well-documented industry pattern that human error drives many reported email-related breaches, not a Smartlockr-specific outcome study.
Misdirected and unencrypted email remains a persistent, well-documented cause of data breaches, particularly in healthcare and government, both of which Smartlockr specifically targets and where regulatory exposure from email mistakes is high.
Why CISOs Should Care
Smartlockr gives CISOs a low-friction way to close one of the most common and hardest-to-train-away breach vectors—human error in outbound email—without forcing employees to change their existing email client or workflow.
What Makes It Different
Rather than only blocking risky outbound emails, Smartlockr nudges senders at the point of sending and frames human error as the core threat model, differentiating it from DLP tools built primarily around hard policy blocks.
The Matrix Verdict
53/100 — INCREMENTAL INNOVATOR
A mature, well-funded Dutch secure-email vendor with a clear and credible niche (human-error-driven email breaches in regulated industries), though its technology is an incremental refinement of an established category rather than a disruptive new approach.
Editorial Note: Claims vs. Verified Findings
Independently verified: founding year, HQ, and the 2021/2023 funding rounds and investors are corroborated by Silicon Canals, Dealroom, and Crunchbase. Vendor-sourced and unverified: the '500+ organizations' customer count and any implied breach-prevention efficacy figures come from Smartlockr's own site and blog rather than a named customer case study or third-party audit.
