Low risk. 3 critical or high findings in GDPR outside view and DNS health.
Xolphin BV is a well-established Dutch company specializing in the provision of SSL certificates and digital signatures, serving primarily businesses and individuals seeking secure online communication solutions. Founded in 2002, it has grown to become the largest SSL certificate provider in the Netherlands, leveraging its role as a Registration Authority for Sectigo to offer fast certificate issuance and expert support. The company emphasizes trust and security, demonstrated by its ISO 27001 certification and multiple WebTrust seals, alongside a strong customer base of over 50,000 clients. Technically, the website employs modern web technologies including Google Tag Manager, Google reCAPTCHA, and Cookiebot for consent management, ensuring compliance with privacy regulations such as GDPR. The site is well-structured, mobile-optimized, and integrates multiple language and currency options to serve a broad audience. While no major CMS or hosting provider details are explicitly detected, the performance and SEO practices are good, supporting a professional online presence. From a security perspective, Xolphin maintains a strong posture with HTTPS enforcement, secure form handling via reCAPTCHA, and adherence to ISO 27001 standards. However, there is room for improvement by adding explicit security headers and publishing incident response and vulnerability disclosure policies. No critical vulnerabilities or exposed sensitive data were detected, indicating a mature security environment. Overall, Xolphin presents a trustworthy and professional digital footprint with strong business credibility and compliance. Strategic recommendations include enhancing security header implementation, formalizing incident response communications, and improving accessibility features to further strengthen their security and compliance posture.

Each check with its score, findings and the evidence it collected.

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.
