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

Linkbuilding.dk is a Danish SEO-focused website providing educational content, free link catalogs, and professional advice on linkbuilding and off-site SEO. The site is operated under visibility.group ApS and affiliated with companies like We Digitize, MadEye Digital, and Scriptomist, indicating a small but specialized business presence in the Nordic SEO market. Technically, the website is built on WordPress using Elementor and NitroPack, ensuring good performance and mobile optimization. Security posture is adequate with HTTPS and reCAPTCHA usage, but lacks security headers and explicit privacy or cookie policies, which are areas for improvement. Overall, the website is professional and trustworthy with moderate risk due to missing privacy compliance elements.

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 operates as a niche SEO education and resource platform targeting website owners and digital marketers interested in linkbuilding. Its market position is supported by affiliations with established SEO companies, providing credibility and a networked ecosystem. The business model focuses on content provision and SEO consultancy, with growth potential in Nordic markets. The presence of multiple subsidiaries suggests a strategic approach to covering various SEO-related services including content creation and linkbuilding. The company maintains transparent contact information and business registration details, enhancing credibility.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and Google reCAPTCHA is implemented on forms to mitigate spam. However, the absence of security headers such as Content-Security-Policy and DNSSEC reduces the overall security posture. There is no visible incident response or vulnerability disclosure policy, which could impact readiness for security incidents. No exposed sensitive data or vulnerable libraries were detected, but the lack of privacy and cookie policies indicates compliance gaps with GDPR. Enhancing security headers and formalizing security policies would improve the security culture and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC for the domain to improve DNS security.
  4. Publish incident response and vulnerability disclosure policies with dedicated contact channels.
  5. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.

Technical notes

Notes

The website uses a modern WordPress CMS with Elementor page builder and NitroPack for performance optimization, resulting in fast load times and good mobile responsiveness. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but could be improved. The hosting provider is not explicitly identified. The site uses Google Tag Manager and Google reCAPTCHA for analytics and security. There is some technical debt in missing security headers and lack of DNSSEC. Overall, the technical infrastructure is solid but can benefit from enhanced security and privacy implementations.
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.
