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

Reha Zentrum Flensburg is a well-established ambulatory rehabilitation and physiotherapy center located in Flensburg, Germany, with a history dating back to 1993. The website clearly targets patients seeking rehabilitation services, emphasizing local accessibility and professional care. The business positions itself as one of the oldest and northernmost EAP centers in Germany, highlighting its experience and competence. Technically, the website is built on Joomla CMS with modern UIkit and Yootheme frameworks, incorporating Leaflet.js for map functionality. The site is mobile-optimized and presents content in a clear, professional manner. Performance is moderate with good SEO practices but lacks some advanced accessibility features. From a security perspective, the site uses HTTPS with a good SSL configuration and employs CSRF tokens in forms, but lacks important security headers and a cookie consent mechanism. No vulnerability disclosure or incident response information is provided, which could be improved to enhance trust and compliance. WHOIS data aligns well with the business claims, showing a consistent and legitimate domain registration. Overall, the website is professional, trustworthy, and suitable for its healthcare audience, but could benefit from enhanced privacy compliance and security best practices to further strengthen its posture.

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

  2. Security headers

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 business operates in the healthcare sector, focusing on ambulatory rehabilitation and physiotherapy services. It targets patients in the Flensburg region, leveraging its long-standing market presence and proximity to local hospitals to build trust. The business model is service-oriented, relying on patient referrals and prescriptions for rehabilitation. The website content and structure support patient engagement and information dissemination but lack integration with social media or advanced marketing tools. No partnerships or subsidiaries are evident from the domain or website content. Growth indicators include a comprehensive service offering and a professional team, but digital marketing and analytics usage appear minimal. The company maintains a consistent brand image and clear contact channels, which supports credibility and patient trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and CSRF protection in forms. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces its defense-in-depth. The lack of a cookie consent mechanism and explicit privacy compliance features indicates partial GDPR adherence. No visible vulnerability disclosure or incident response contacts limit transparency and responsible security practices. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site does not appear to use tracking or advertising scripts that could introduce privacy risks. Overall, the security posture is adequate for a healthcare informational site but should be improved to meet higher compliance and security standards.

Recommendations

  1. Implement a comprehensive cookie consent banner and cookie policy to comply with GDPR requirements.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance browser security.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Include incident response contact information, such as a dedicated security or abuse email address.
  5. Enhance accessibility features to improve usability for all users, including those with disabilities.

Technical notes

Notes

The website uses Joomla CMS with Yootheme templates and UIkit framework, providing a modern and responsive design. Leaflet.js is used for interactive maps, enhancing user experience. The site loads multiple CSS and JS assets asynchronously or deferred, which helps performance. However, no advanced analytics or marketing tools are detected, indicating limited digital tracking. The site is mobile-optimized with good navigation clarity and structured content. No broken links or errors were found in the HTML content. Hosting provider details are not explicitly identified from the content or WHOIS data. Overall, the technical implementation is solid but could benefit from enhanced SEO metadata and accessibility improvements.
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.
