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

Hundeschule ALLERHUNDE is a professional dog training school established in 2005, serving the Landkreis Celle region in Germany. The business offers a range of services including individual and group training, puppy courses, behavioral consultations, and certification preparation such as the Sachkundenachweis and Hundeführerschein. The website reflects a small, regionally focused service provider with a consistent brand and clear communication channels including phone, email, and social media. Technically, the site uses standard web technologies like HTML5, CSS, JavaScript, jQuery, and Bootstrap, providing a moderate performance and basic mobile optimization. Security posture is moderate with no visible security headers or explicit HTTPS confirmation, and privacy compliance is partial due to the absence of cookie consent mechanisms. Overall, the domain registration data aligns well with the business claims, supporting legitimacy and trustworthiness.

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

  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';…

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 niche market of dog training and behavioral consulting, targeting dog owners in a defined geographic area. Its competitive advantage lies in its certification by the Tierärztekammer Niedersachsen and a long-standing presence since 2005. Revenue streams likely derive from training sessions, group courses, and certification preparation. The business maintains an active social media presence to engage customers and enhance visibility. There is no evidence of partnerships or subsidiaries. The business model is service-oriented with a focus on personalized training and education.

Security posture

The website demonstrates a basic security posture with no detected advanced security headers or incident response policies. The absence of HTTPS confirmation is a concern and should be addressed promptly. No vulnerabilities or exposed sensitive data were found in the HTML content. The lack of a vulnerability disclosure policy or security.txt file indicates limited formal security governance. Incident response contact channels are not provided, which could delay handling of security incidents. Overall, the security maturity is low to moderate, suitable for a small business but with room for improvement.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Introduce a cookie consent banner and update privacy policies to explicitly address GDPR compliance.
  4. Publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly update all JavaScript libraries and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website is built using classic web technologies including HTML5, CSS, JavaScript, jQuery, and Bootstrap framework. The site structure is clear and navigation is well organized with dropdown menus and links to various service pages. Performance is moderate with no explicit optimization indicators. Mobile responsiveness is basic but functional. No CMS or advanced platform detected, indicating a custom or static site approach. No analytics or tracking scripts were found, suggesting minimal technical tracking. The site could benefit from modern SEO and accessibility improvements to enhance reach and usability.
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.
