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 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

    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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  3. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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 holds a strong market position as a trusted comparison tool in the German healthcare insurance sector. Its business model is based on providing detailed, user-friendly information and facilitating membership applications, likely monetized through partnerships or advertising with insurance providers. The site serves a broad audience with tailored tools such as a contribution calculator and regional filters. Its partnership ecosystem includes recognized insurance companies like DAK and hkk. The platform's longevity and detailed data collection indicate a mature operation with a focus on user trust and transparency.

Security posture

The site employs HTTPS and uses CSRF tokens in forms, indicating basic security hygiene. However, it lacks visible security headers such as CSP or HSTS, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a vulnerability disclosure policy or security contact reduces transparency in incident response readiness. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the security posture is moderate but could be improved with additional headers and explicit policies.

Recommendations

  1. Implement comprehensive security headers including Content Security Policy (CSP), HSTS, and X-Frame-Options.
  2. Add a cookie consent banner to comply fully with GDPR requirements.
  3. Publish a vulnerability disclosure policy and security.txt file to improve transparency and incident response.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Provide direct contact emails for support and security inquiries to increase trust and responsiveness.

Technical notes

Notes

The website uses a modern JavaScript stack including ES6 modules, jQuery, and lazy loading for images, contributing to good performance and mobile optimization. The site is hosted on DomainControl nameservers, a common registrar service. The HTML structure is valid and SEO optimized with appropriate meta tags and Open Graph data. However, no CMS was detected, suggesting a custom or static site architecture. Performance is moderate with room for improvement in accessibility and security headers. The site includes interactive forms with CSRF protection, indicating attention to secure data handling.
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.
