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

7 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

    • High

      Detected services: Google Analytics, Facebook, LinkedIn, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

    • High

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

Boligkontoret Århus operates as a regional housing office with a clear focus on tenant services and housing management in Aarhus, Denmark. Their market positioning is stable with a medium-sized footprint and a business model centered on providing housing solutions and support to residents. Revenue streams likely derive from housing management fees and tenant services. The target customer segment includes local residents and housing applicants. The company leverages partnerships for payment processing and maintains active social media engagement to support community relations. Growth indicators include a long domain age and consistent branding. The partnership ecosystem includes payment service providers, but no subsidiaries or parent companies are indicated. Operationally, the company emphasizes accessibility and user-friendly digital services, though modernization of technical infrastructure could enhance competitive advantage.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and a Content Security Policy to block mixed content. Login forms require mandatory fields, reducing risk of injection or unauthorized access. However, the absence of DNSSEC and additional security headers such as HSTS and X-Frame-Options represents a gap in defense-in-depth. No security.txt or vulnerability disclosure policy is published, limiting transparency and incident response readiness. Privacy policies and cookie consent mechanisms indicate GDPR awareness, but no explicit incident response contacts or security frameworks are referenced. Overall, the security posture is adequate for the business type but could be improved by adopting best practices and formalizing security policies to reduce risk and enhance trust.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security policy and incident response contact information on the website.
  3. Implement a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Add additional HTTP security headers such as HSTS, X-Frame-Options, and X-XSS-Protection.
  5. Regularly review and update technical stack to modern frameworks to improve performance and security.

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.
