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

1 finding rated critical or high. Fix these first.

  1. 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 targets both residential and commercial customers seeking customized heating textile solutions that combine comfort, energy efficiency, and environmental benefits. Their business model revolves around manufacturing and direct sales of patented heating textiles, emphasizing low-voltage safety and environmental sustainability. The presence of ISO certification and multiple production locations indicates a medium-sized enterprise with established market presence in Germany and potentially Europe. The website links to the parent company site jahntextil.de, reinforcing brand consistency. No social media or extensive marketing tools were detected, suggesting a focus on direct customer engagement and B2B relationships.

Security posture

The website employs HTTPS with a good SSL configuration and includes a cookie consent mechanism compliant with GDPR. Forms include explicit privacy acceptance checkboxes, reducing legal risk. However, no dedicated security policy or incident response information is published, which could be improved to enhance transparency and readiness. No security headers were detected in the provided data, and no known vulnerabilities or exposed sensitive data were found. The absence of analytics and tracking scripts reduces privacy risks but also limits behavioral insights. Overall, the security posture is good but could benefit from formalized policies and enhanced HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and incident response procedures.
  2. Add security-related HTTP headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Include contact information for security incidents or abuse reports (e.g., security@ or abuse@ email).
  4. Regularly audit and update third-party plugins and scripts to mitigate vulnerabilities.
  5. Consider integrating privacy-friendly analytics to gain insights while maintaining compliance.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor page builder and jQuery 3.7.0. It uses Autoptimize for asset optimization, contributing to moderate performance. The site is mobile optimized with responsive design and includes SEO best practices such as meta tags and structured data (JSON-LD). Hosting provider details are not explicitly available. The site does not use heavy tracking or advertising scripts, which benefits privacy and performance. Accessibility features are basic but present. The technical stack is stable and appropriate for the business size and needs, with room for improvement in security headers and performance tuning.
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.
