Risk levelMedium

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

City Apartment is a small real estate business specializing in subletting stylish and unfurnished apartments in prime locations of Copenhagen, targeting private individuals and posted workers abroad. The website demonstrates a professional digital presence built on WordPress with modern tools such as Elementor and Astra theme, enhanced with SEO best practices and structured data for improved search visibility. Cookie consent is actively managed via Cookiebot, reflecting awareness of privacy compliance requirements. Security posture is adequate with HTTPS enabled and consent management, but lacks advanced security headers and DNSSEC, which could be improved. No explicit privacy policy or terms of service were found, which is a compliance gap. Contact information is not explicitly presented, which may affect user trust and business credibility. Overall, the website is functional, professional, and moderately secure, with room for improvement in privacy and security transparency.

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
  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 company operates in the real estate sector, focusing on apartment rentals in Copenhagen. Its business model revolves around subletting unfurnished apartments with an emphasis on high service and security. The domain age of 20 years supports a stable market presence. The website targets a niche audience of private renters and posted workers, leveraging digital marketing tools such as Google Ads and Analytics for customer acquisition. The absence of explicit contact details and legal policies may limit trust and conversion potential. The company appears to maintain consistent branding and content quality, positioning itself as a reliable local real estate service provider.

Security posture

The website employs HTTPS and integrates cookie consent mechanisms, indicating baseline security and privacy awareness. However, the lack of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which may hinder timely security issue reporting and resolution. Tracking scripts are managed with consent, but data retention policies are not disclosed. Overall, the security posture is moderate but could benefit from enhanced technical controls and transparency.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement DNSSEC to secure DNS resolution and prevent spoofing.
  3. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website.
  4. Provide clear contact information including emails and phone numbers for customer support and incident reporting.
  5. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible security communication.

Technical notes

Notes

The website is built on a modern WordPress platform using Astra theme and Elementor page builder, supported by Google Tag Manager and Cookiebot for analytics and privacy management. The site loads multiple minified CSS and JS assets, indicating optimization efforts. Mobile responsiveness and SEO metadata are well implemented. Performance is moderate, with potential improvements in caching and asset delivery. The absence of DNSSEC and security headers represents technical debt in security. Overall, the technical infrastructure is solid but can be enhanced with additional security and compliance features.
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.
