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

2 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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

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 healthcare insurance sector, focusing on statutory health insurance services in Germany. Its business model revolves around providing health insurance coverage and related health services to individuals, leveraging digital tools for service delivery such as online sick note processing. The membership in BKK Landesverband Bayern suggests collaboration within a network of regional health insurers, enhancing competitive positioning. Revenue streams likely include statutory health insurance contributions. The target customer segment is insured persons in Bavaria and possibly wider Germany. The website's use of modern consent and analytics tools indicates a commitment to regulatory compliance and digital maturity. No parent or subsidiary companies are identified, suggesting an independent regional entity. The company maintains a consistent brand presence and trust signals through official legal status and transparent contact information.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a comprehensive cookie consent mechanism that allows users to control preferences, statistics, and marketing cookies. Use of Cookiebot and Matomo analytics reflects privacy-conscious data collection practices. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. No vulnerability disclosure program or security.txt file was found, which could enhance trust and incident handling readiness. Overall, the security posture is good but could be strengthened by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement and publish explicit security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Develop and make publicly available a security policy and incident response contact information to improve transparency and preparedness.
  3. Establish a vulnerability disclosure program or publish a security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are used.
  5. Enhance user trust by providing more detailed information on data protection officer contact and data retention policies.

Technical notes

Notes

The website uses a modern technology stack including asynchronous JavaScript loading, web fonts, and JSON-LD structured data for SEO and rich snippets. Cookiebot is integrated for GDPR-compliant cookie consent management, and Matomo Tag Manager is used for privacy-friendly analytics. The site is mobile-optimized and includes accessibility features such as sign language videos and easy language content. Performance appears moderate with preloading of fonts and asynchronous script loading. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site uses canonical URLs and Open Graph metadata for social media sharing. Technical debt appears low, but the absence of some security headers and incident response mechanisms indicates room for modernization and risk mitigation.
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.
