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

Tierhalter-Wissen.de is a German online education platform specializing in providing knowledge and online courses for animal owners and dog breeders. The website focuses on animal health and nutrition, aiming to help its target audience avoid mistakes in animal care. The platform uses WordPress with LMS and e-commerce plugins to deliver its services. Technically, the site employs modern technologies and is mobile-optimized with good SEO practices. Security-wise, the site uses HTTPS and has no visible vulnerabilities or blocking mechanisms, but lacks published privacy and security policies. Overall, the site is functional and professional but could improve transparency and compliance by adding privacy, terms, and contact information.

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. 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 education sector, targeting a niche market of animal owners and breeders in Germany. Its business model revolves around online courses and knowledge dissemination. The company appears small-sized with a consistent brand presence. The lack of visible contact details and certifications limits trust signals. The platform integrates with marketing tools like Mailchimp and tracking via Google Tag Manager, indicating some marketing maturity. There is no evidence of partnerships or subsidiaries from the data provided.

Security posture

The website has a good security baseline with HTTPS enabled and no WAF blocking detected. However, it lacks visible security headers and published security or incident response policies. No vulnerability disclosure or security.txt files were found. The absence of privacy and terms policies is a compliance gap. The site should enhance its security posture by implementing security headers, publishing policies, and ensuring plugin security.

Recommendations

  1. Publish a comprehensive privacy policy to improve GDPR compliance and user trust.
  2. Add a terms of service page to clarify user agreements and legal protections.
  3. Implement security headers such as Content-Security-Policy and X-Frame-Options.
  4. Provide clear contact information including emails and phone numbers for support and incident reporting.
  5. Regularly audit and update WordPress plugins to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress using popular plugins like LearnDash for LMS and WooCommerce for e-commerce. It uses Elementor for page building and Ultimate Member for user management. The site loads CSS and JS assets efficiently with minification and caching. Mobile optimization is good, and SEO meta tags are properly configured including Open Graph and JSON-LD structured data. Performance is moderate but could be improved with further optimization. Accessibility is basic and could be enhanced. Hosting provider details are not explicitly found.
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.
