0–100, higher is better. How it is calculated

Mijndomein is a well-established Dutch company specializing in domain registration, web hosting, and website building services, targeting small to medium businesses and individual entrepreneurs primarily in the Netherlands. The company operates under the parent company TransIP Group B.V., with a strong market presence and a comprehensive service offering including managed WordPress hosting and webshop solutions. Their website is professionally designed, mobile-optimized, and provides clear navigation and relevant content to their target audience. Technically, the website employs a modern technology stack including Bootstrap, jQuery, and integrates multiple third-party services such as Hubspot for marketing automation, Cookiebot for cookie consent management, and Cloudflare for CDN and security. The site demonstrates good performance and SEO practices, though accessibility features could be improved. The use of HTTPS and a Content Security Policy enhances the security posture. From a security perspective, Mijndomein shows a mature approach with enforced HTTPS, cookie consent mechanisms, and reputable third-party integrations. However, there is room for improvement by adding additional security headers and publishing explicit security policies and incident response contacts. No critical vulnerabilities or exposed sensitive data were detected. Overall, Mijndomein presents a low-risk profile with strong business credibility, good privacy compliance, and a solid technical foundation. Strategic recommendations include enhancing security headers, formalizing security policies, and improving accessibility to further strengthen their digital maturity and trustworthiness.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

2 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

      SSL Certificate Expires Soon

      SSL certificate expires in 29 days

      What to do: Renew SSL certificate before expiration

Results by check

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

How this score is calculated

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.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

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.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Mijndomein holds a strong position in the Dutch domain registration and hosting market, leveraging its parent company TransIP Group B.V. to provide a broad range of services. Their business model focuses on recurring revenue from hosting and domain services, supplemented by value-added offerings like website builders and managed WordPress hosting. The company targets SMEs and individual entrepreneurs, a segment that demands ease of use and reliable support. Their partnership ecosystem includes major players like Hubspot and Cloudflare, enhancing marketing and security capabilities. Growth indicators include active use of analytics and marketing automation, and a well-maintained support infrastructure via Zendesk. The company’s operations reflect a professional and consistent branding strategy, supporting customer trust and retention.

Security posture

Mijndomein demonstrates a solid security posture with HTTPS enforced site-wide, a Content Security Policy to upgrade insecure requests, and a comprehensive cookie consent mechanism aligned with GDPR requirements. The integration of Cloudflare provides additional protection against DDoS attacks and enhances performance. The use of reputable analytics and marketing tools is balanced with privacy compliance. However, the absence of some security headers such as X-Frame-Options and Strict-Transport-Security represents an area for improvement. No incident response or vulnerability disclosure information is publicly available, which could be addressed to improve transparency and readiness. Overall, the security maturity is good, with no critical vulnerabilities detected, but with opportunities to formalize policies and enhance header configurations.

Recommendations

  1. Implement additional security headers including X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security to harden the site against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and provide clear contact channels for security issues.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance website accessibility compliance to improve usability for all users and meet regulatory standards.
  5. Establish and communicate data retention policies related to analytics and user data to strengthen privacy compliance.

Technical notes

Notes

The website is built on a modern and stable technology stack featuring Bootstrap 5 and jQuery, supported by a custom CMS platform. It integrates multiple third-party services for analytics (Google Analytics, Hotjar, Microsoft Clarity), marketing automation (Hubspot), and security/CDN (Cloudflare). Performance is moderate with good mobile optimization and SEO practices. The site uses asynchronous loading for scripts and employs cookie consent management via Cookiebot, indicating a mature approach to privacy. Technical debt appears low, but accessibility features are basic and could be improved. The hosting infrastructure is robust, leveraging Cloudflare’s CDN and security features. Overall, the technical implementation supports business goals effectively with room for incremental improvements.
Standards and sources

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.
