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

6 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

Jahn GmbH & Co. KG holds a strong market position in the manufacturing sector of technical textiles, leveraging over 190 years of combined experience through its legacy companies. The business model focuses on B2B manufacturing and development services, targeting industrial clients needing customized textile solutions. The company demonstrates growth through mergers and multiple production locations. Its ISO 9001 certification and detailed company history enhance credibility. The partnership with Heiztextil.de indicates a collaborative ecosystem in specialized textile markets. The website content and structure support clear communication of services and company values.

Security posture

The website employs HTTPS with a valid SSL configuration, ensuring encrypted communications. A cookie consent banner is implemented, supporting privacy compliance. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. There is no visible incident response or security contact information, nor a vulnerability disclosure policy. No vulnerabilities or exposed sensitive data were found in the content. Overall, the security posture is good but could be enhanced by adopting additional HTTP security headers and publishing security policies.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish an incident response policy or security contact information to improve transparency and readiness.
  3. Consider adding a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update WordPress plugins and themes to mitigate potential vulnerabilities.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress 6.8.3 using Bootstrap 3.3.7 and jQuery 3.7.1, combined with several plugins such as Fresh Framework, Owl Carousel, Magnific Popup, and A3 Lazy Load for performance optimization. The site is mobile responsive and uses GTranslate for language switching. Performance is moderate, with lazy loading implemented for images. SEO is supported by proper meta tags and structured content. No hosting provider information was detected. The technical stack is modern but could benefit from updates to Bootstrap and jQuery versions for improved security and performance. No critical technical debt or risks were identified.
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.
