REST API

Developer portal ›

SecuMailer has a REST API for sending secure emails. Both the GDPR and the NTA 7516 functionality are fully accessible via this API.

The API is documented with OpenAPI specification 3.0.1.

The REST API has webhook functionality, which means that the SecuMailer platform can communicate email events with an HTTPS endpoint of the sender.

SMTP API

The SMTP API is usually the simplest integration option for many backend applications because backend applications often have a provision for an SMTP client on board.

We have successfully integrated for customers with Salesforce, SAP and Centric. We have also successfully integrated with patient file systems such as Medisoft Dossier Manager.

GraphQL API

The SecuMailer platform offers insight into email events. This can be done on the basis of a (push) webhook call (see REST API above) and on the basis of a (pull) GraphQL endpoint.

Data Loss Prevention

Data Loss Prevention

Reduce data breach risk

Prevent sensitive information from leaving the organization by mistake.

Stay compliant

Meet regulations like GDPR and NTA 7516 without extra user effort.

Stay in control

Decide how sensitive information is handled and secured, based on clear policies.

Why Choose SecuMailer’s DLP

SecuMailer’s DLP applies situational security: the right protection at the right time, without disturbing the user. Unlike many solutions that expect employees to choose a security level themselves, often leading to errors and frustration. SecuMailer automates this process. Sensitive content is detected, the right measures are applied instantly, and the system continues to learn from behavior while remaining fully manageable through organizational policies.

This makes it especially valuable for:

  • Privacy officers: gain insight and control

  • Security teams: get context-based signals and stay in charge

  • Users: work without distraction, confident they can’t cause data leaks.

  • Executives: meet compliance requirements and avoid fines or reputational damage.

How does DLP work?

Step 1

The user sends an email like a regular email.

Step 2

The system automatically scans the content and attachments for sensitive information.

Step 3

Smart analysis (patterns, context, and tone) determines whether there is a potential risk.

Step 4

Based on the risk, the system applies the right action: strengthening security, blocking the email with feedback, or alerting the security team.

Features at a glance

Discover what makes SecuMailer scalable, seamless, and future-ready.

Integrate SecuFiler as a page on your organization’s website. Through this page, your customers can easily send all confidential documents securely to your organization.

Send one or multiple files at a time up to a total size of 5TB. This is equivalent to approximately 1,250,000 high-resolution photos, so in almost all cases, it’s more than enough!

With SecuFiler, you can easily send a wide range of file types. It’s possible to send all common file types, not just PDFs, but also documents, photos, and videos.

With the SecuFiler Link Wizard, you can generate a pre-filled link to share with your customer. Your customer only needs to select the files and click send.

Do you want the recipient to undergo additional authentication? This can be done by performing an extra 2FA, making the large file fully NTA 7516-compliant. Therefore, it is highly suitable for medical and legal information.

Ready to share and manage sensitive data securely?

Seamless, secure email that respects privacy, meets legal standards, and feels effortless—for both your team and the people you serve.
