How we keep your data truly secure

With us, information security is not in the background, but at the heart of what we do. With rigorous certifications, secure data centers and a team that's alert every day, we make sure your data is truly in safe hands. Find out how we do it...

Picture this: you fill out a questionnaire or view your results on our platform. That may feel obvious, but behind the scenes something big is at play. After all, you are sharing personal data - sometimes even sensitive (medical) information. Then, of course, you want to be sure that that data is safe.

At Johan.nl, we believe that trust is not created by saying that you are safebut by proving it proving it every day. That is why information security is not an afterthought for us, but the core of what we do at Johan.nl.

Safety starts with people

The story starts with our team. Everyone at Johan.nl - from the developers who develop the technology to the support colleagues who have daily contact with customers and from management to implementation - knows that security is their responsibility. New colleagues therefore receive training, we keep each other sharp and there is always a privacy officer and security officer looking on. Security is therefore not something of "IT", but of all of us!

Technology as a lock on the door

Of course, we also technically ensure that your data remains in safe hands. All data is transmitted and stored encrypted. Access to the platform is always via two-factor authentication and before new features go live, they are extensively tested - sometimes even with external hackers trying to penetrate. Only if everything holds up will we release new features!

Independent check

We can say ourselves that we do everything right, but independent evidence counts much more. That is why we are certified according to ISO 27001 and NEN 7510. These are international and Dutch standards that strictly test whether your information security is really in order. This is reassessed twice a year in the form of extensive audits.

Servers close to home

The location of the data is also important. We deliberately choose Dutch data centers that are highly secure and meet our requirements. In addition, we always make backups at a different location, so your data will not be lost even in a disaster.

Always in motion

Security is never "done." New technologies, new threats, new ways of working - we keep learning and improving. When incidents occur, they are not only resolved early, but also used to become even better.


In short: this is in safe hands with Johan.nl. And that is not an empty promise, but a daily commitment from our entire team!
