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

1 finding 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 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

  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • 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

Keolis Danmark A/S holds a strong market position as a major public transport operator in Denmark, supported by its parent global company Keolis. The company operates in the transportation sector, focusing on bus and light rail services. Its business model relies on public contracts and service delivery, with recent growth through acquisition of Anchersen A/S. The website indicates a focus on quality, environmental responsibility, and passenger satisfaction. The partnership with emply.com for recruitment shows a structured approach to talent acquisition. The company maintains a professional digital presence with consistent branding and social media engagement primarily on LinkedIn. Revenue streams are likely from public transport contracts and service agreements. The company targets public transport users, municipalities, and potential employees. The website content and structure support these business goals effectively.

Security posture

The security maturity level of the website is moderate to good. HTTPS is enforced with strong SSL configuration, and cookie consent is managed via Cookiebot, indicating compliance with GDPR cookie requirements. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms limits transparency and readiness. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended best practices. No exposed sensitive data or vulnerable libraries were found in the HTML content. The use of modern libraries and frameworks reduces risk, but continuous monitoring and improvements are advised. The company should consider publishing a security policy and incident response information to enhance trust and preparedness. Overall, the security posture is adequate but can be strengthened with additional controls and disclosures.

Recommendations

  1. Publish a comprehensive privacy policy page to complement the cookie policy and improve GDPR compliance.
  2. Add a dedicated security policy page outlining security frameworks, practices, and incident response procedures.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website security by adding HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Improve accessibility features to meet higher standards and ensure inclusivity for all users.

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.
