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

5 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Vestforbrænding operates in the energy sector with a focus on waste-to-energy solutions and district heating. Their business model revolves around providing essential utility services with an emphasis on sustainability and climate impact reduction. The company targets a broad audience including private households, commercial clients, and local governments. Their market position as the largest in Denmark in their sector is supported by extensive infrastructure and service offerings. The website content and structure indicate a strategic focus on education, customer engagement, and transparency. Partnerships with cookie consent providers and use of Cloudflare for performance and security indicate a mature operational ecosystem. The absence of explicit terms of service or security policies suggests areas for future enhancement in governance and compliance communication.

Security posture

The website enforces HTTPS and employs cookie consent mechanisms compliant with GDPR, reflecting a good baseline security posture. No WAF or blocking mechanisms were detected, indicating open accessibility. Security headers are partially present but could be strengthened by adding explicit Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers. No exposed sensitive data or vulnerable libraries were found in the HTML content. The lack of published security policies or incident response information is a gap in transparency and preparedness. Overall, the security posture is solid but could benefit from enhanced header configurations and public disclosure of security governance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a comprehensive security policy and incident response plan on the website.
  3. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Maintain and regularly update cookie and privacy policies to ensure ongoing GDPR compliance and user trust.

Technical notes

Notes

The website is built using modern web technologies including Next.js and React, ensuring a performant and responsive user experience. Hosting appears to leverage Cloudflare services for CDN and security benefits. The integration of Matomo analytics provides privacy-focused user tracking. The site is well-structured with proper meta tags for SEO and social media sharing (Open Graph and Twitter cards). Accessibility features such as focus trapping in modals and keyboard navigation are implemented. The cookie consent mechanism is robust and user-friendly. Performance is optimized with preloading and deferred scripts. Overall, the technical infrastructure is modern, scalable, and aligned with best practices for user experience and privacy.
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.
