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

Thomas Dahm operates a professional website showcasing his expertise as a graphic designer and WordPress developer, targeting creative entrepreneurs seeking marketing design and e-commerce solutions. The site features a portfolio, e-commerce store, newsletter subscription, and links to related projects and social media, positioning him as a niche creative professional with a strong digital presence. Technically, the website is built on WordPress with modern plugins and SEO optimizations, hosted under a reputable registrar with DNSSEC and HTTPS enabled, indicating a mature digital infrastructure. Security posture is solid with encrypted connections and no visible vulnerabilities, though the absence of privacy and cookie policies presents compliance risks. Overall, the site is trustworthy and professionally maintained but would benefit from enhanced privacy compliance and security headers to improve user trust and regulatory adherence.

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

11 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The business is positioned as a small-scale creative service provider with diversified offerings including design services, digital products, and curated content. The target market includes creative entrepreneurs and marketers, with revenue likely generated through service contracts and e-commerce sales. The presence of partner domains and related projects indicates a collaborative ecosystem enhancing market reach. The long domain age and consistent branding support a stable market presence. However, the lack of explicit business contact details such as phone numbers or physical addresses may limit some customer trust and engagement channels.

Security posture

The website demonstrates a good security baseline with HTTPS and DNSSEC enabled, reducing risks of interception and DNS spoofing. No security headers were detected in the HTML, which could be improved to mitigate clickjacking, MIME sniffing, and other web attacks. The site uses reputable WordPress plugins but lacks visible incident response or vulnerability disclosure policies, which are important for transparency and rapid mitigation of security issues. No sensitive data exposure or vulnerable libraries were identified in the content. Privacy compliance is weak due to missing policies and consent mechanisms, posing regulatory risks especially under GDPR.

Recommendations

  1. Publish a comprehensive privacy policy and cookie consent banner to ensure GDPR compliance.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Create and publicize an incident response and vulnerability disclosure policy to enhance security transparency.
  4. Regularly audit and update WordPress plugins to mitigate vulnerabilities.
  5. Improve accessibility features to broaden audience reach and compliance.

Technical notes

Notes

The website is built on a modern WordPress CMS version 6.3.2 with WooCommerce for e-commerce functionality. It leverages jQuery, Google Analytics, Google Tag Manager, and Mailchimp for marketing and analytics. The site uses Rank Math SEO plugin and structured data for enhanced search engine visibility. Hosting is through One.com A/S, a known registrar with DNSSEC enabled, indicating good domain security. Performance is moderate with good mobile optimization. Some technical debt is implied by the use of older jQuery versions and lack of advanced accessibility features. Overall, the technical infrastructure is solid but could benefit from performance tuning and enhanced security configurations.
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.
