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

5 findings rated critical or high. Fix these first.

  1. 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

      No email authentication configured

      Domain is vulnerable to email spoofing

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

  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 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. 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 business operates in the healthcare sector, focusing on preventive nutrition coaching linked to the BKK health insurance network. Its business model revolves around providing free online coaching services and interactive content to engage users and promote healthier lifestyles. The company leverages partnerships with zone35 GmbH & Co. KG and the central prevention portal for course offerings. The platform's niche positioning and consistent branding support a medium-sized operation with a stable market presence in Germany. The absence of direct monetization or e-commerce suggests a focus on service and education rather than sales. Growth potential lies in expanding interactive features and formalizing compliance and security frameworks.

Security posture

The website employs HTTPS with a valid SSL configuration, ensuring encrypted data transmission. Forms for login and online checks use secure input types, and cookie consent mechanisms are in place to comply with GDPR. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is provided, which could hinder rapid mitigation of security issues. No known vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security posture is good but could be enhanced by adopting additional HTTP headers and publishing security policies.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a formal security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly audit and update third-party libraries and CMS extensions to mitigate potential vulnerabilities.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system, supplemented by jQuery and Bootstrap for frontend interactivity and responsiveness. The use of extensions like powermail for forms and cookieconsent2 for privacy compliance indicates a mature technical setup. Performance is moderate with no evident blocking scripts or heavy resources. Mobile optimization is good, supported by responsive design elements. SEO is addressed with appropriate meta tags and structured navigation. However, the site lacks advanced analytics or tracking tools, which could limit marketing insights. Hosting details are not explicitly disclosed, but DNS points to zone35 name servers, aligning with the company branding. Overall, the technical infrastructure is solid with opportunities for modernization and enhanced security.
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.
