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

6 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

      What to do: Implement a cookie consent banner that appears on first visit

  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

      Domain is vulnerable to email spoofing

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

    • 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

  • Security headers: 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

The company operates in the real estate sector with a focus on residential and commercial property management in Saarbrücken. It targets local residents, businesses, and potential tenants. The business model centers on direct property rental and management services, supported by municipal partnerships. The website content and linked domains indicate strong local integration and a stable market position. No direct revenue streams or parent company information are disclosed. The presence of job and training offers suggests organizational growth and community engagement. The partnership ecosystem includes the official Saarbrücken city website and related housing services, reinforcing credibility.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and no sensitive data leaks are evident. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, limiting transparency. The use of third-party tracking via etracker is balanced with cookie blocking and Do Not Track respect, but no explicit cookie consent banner is present. Overall, the security culture appears cautious but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Introduce a visible cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and preparedness.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting and demonstrate security commitment.
  5. Enhance contact information visibility by including verified company emails and phone numbers on the website.

Technical notes

Notes

The website is built on a modern technology stack featuring jQuery 3.7.1, Owl Carousel, Air Datepicker, Foundation framework, Select2, and accessibility tools like ReadSpeaker. The CMS is likely TYPO3, inferred from backend URL patterns. Performance is moderate with some caching and minified CSS/JS assets. Mobile optimization and accessibility are good, with language switching and responsive navigation. SEO is basic with meta tags and Open Graph images but lacks structured data like JSON-LD. Tracking is done via etracker with cookie blocking enabled. The site could improve by adding structured data, optimizing performance further, and enhancing SEO metadata.
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.
