deSEC e.V. · Technology · Germany
Medium risk. 2 critical or high findings in GDPR outside view.
deSEC e.V. is a non-profit organization based in Berlin, Germany, providing a free, secure DNS hosting service designed with security and privacy in mind. The service leverages open-source software and offers advanced DNS features such as DNSSEC signing, multi-factor authentication, and integration with Let's Encrypt. Supported by notable organizations including ICANN, NLnet Foundation, RIPE NCC, and the European Union, deSEC positions itself as a trusted provider in the DNS hosting niche with a focus on security and automation. Technically, the website is built using modern web technologies including Vue.js with the Vuetify UI framework, and offers a REST API for DNS management. The infrastructure includes a global Anycast network for low-latency DNS resolution. The site is mobile-optimized, fast, and accessible, with a professional design and clear navigation. However, some security best practices such as explicit security headers and cookie consent mechanisms are not evident. From a security perspective, deSEC demonstrates strong practices including HTTPS enforcement, DNSSEC usage, and support for multi-factor authentication. The domain registration data is consistent and legitimate, with a long history since 2014. No critical vulnerabilities or suspicious patterns were detected. The absence of a published security policy or incident response page is a minor gap. Overall, deSEC presents a low-risk profile with a strong security posture and credible business model. Strategic recommendations include enabling DNSSEC on the domain itself, adding security headers, publishing a security policy, and implementing cookie consent to enhance compliance and trust.

Each check with its score, findings and the evidence it collected.
The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Findings that cap the score at 49
Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.
Partial scans
When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
