About URIports

URIports was founded in 2018 by Roeland Kuiper and Freddie Leeman, two developers from the Netherlands with decades of combined expertise in building and operating web security platforms, email infrastructure, and internet standards.

We know web and email security inside out. Not just from reading specifications or documentation, but from many years spent implementing, debugging, and solving these problems at scale.

When we looked at the tools available for security monitoring, we saw the same pattern everywhere: fragmented products, enterprise pricing, and platforms focused on only part of the problem. One tool for DMARC. Another for CSP. Separate dashboards, separate pricing, separate blind spots.

But it is all the same domain. A security failure in email affects your brand just as much as a weakness in browser security or DNS configuration. We believed the monitoring should be unified too.

So we built URIports.

We are independent and intend to stay that way. No investors, no acquisition agenda, no pressure to optimise for anything except building a great product. Our infrastructure runs entirely on dedicated servers in the Netherlands. We are fully GDPR compliant, we do not rely on third-party services, and your data is yours. Full stop.

We publish original research and in-depth technical writing on our blog, covering everything from emerging specification changes to large-scale analysis of email authentication adoption across the internet. We also built LearnDMARC.com, a free interactive tool widely recommended in the sysadmin and security community for learning and testing SPF, DKIM and DMARC. No ads, no tracking, no catch. Just a tool we built because the knowledge should be freely accessible.

We built URIports because the right platform did not exist. Everything since has been about making it the best in its class, held to the standard we'd expect as users ourselves.
