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

KrankenhausExperte is a small German healthcare information website offering a searchable database of over 2,000 hospitals in Germany, along with health-related articles. The platform targets patients and individuals seeking hospital information and facilitates hospital contact and appointment scheduling. Technically, the site uses basic web technologies such as nginx, JavaScript, CSS, and HTML5 but lacks modern CMS or frameworks. Performance and mobile optimization are basic, and no analytics or tracking tools are detected. Security posture is weak due to the absence of HTTPS, SSL certificates, and security headers, exposing users to potential risks. Compliance is poor with no privacy, cookie, or terms of service policies present. Overall, the site is functional but lacks professionalism and trust indicators, limiting its credibility and user confidence.

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

10 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

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 website occupies a niche position in the German healthcare sector as an informational and referral portal for hospitals. It provides value by aggregating hospital data and enabling user evaluations but lacks advanced features or monetization insights. The absence of contact details and certifications reduces business transparency. No partnerships or subsidiaries are evident. Growth potential may be limited without improvements in security, compliance, and user engagement features.

Security posture

The security maturity level is low. Critical issues include the lack of HTTPS and SSL certificates, no security headers, and no DNSSEC. There are no visible vulnerabilities like Heartbleed or POODLE, but the absence of basic protections exposes the site to man-in-the-middle attacks and data interception. No incident response or vulnerability disclosure policies are present. GDPR compliance is questionable due to missing privacy and cookie policies. The site should prioritize implementing HTTPS, security headers, and compliance documentation to improve its security posture.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Add comprehensive privacy and cookie policies with a consent mechanism to comply with GDPR.
  4. Publish clear contact information including emails and phone numbers for support and business inquiries.
  5. Consider adding a vulnerability disclosure policy and incident response contact to enhance security transparency.

Technical notes

Notes

The website is hosted on an nginx server with a single IPv4 address and no DNSSEC or domain protection. The HTML is valid and includes basic CSS and JavaScript for UI elements like a burger menu and lazy loading images. Performance metrics are missing or zero, indicating no measurement or poor optimization. The site lacks modern frameworks or CMS, suggesting a static or custom-built solution. Mobile optimization is basic with responsive viewport settings but limited advanced accessibility features. The absence of analytics and tracking scripts indicates minimal user data collection but also limits insights into user behavior. Technical debt includes missing SSL, no security headers, and incomplete DNS configurations.
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.
