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.

Priority findings

3 findings rated critical or high. Fix these first.

  1. 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

Fleck GmbH holds a strong market position as a niche manufacturer in the roofing accessories sector, leveraging product customization and comprehensive trade partner services to differentiate itself. The business model focuses on B2B relationships with roofing professionals and distributors, supported by digital tools such as configurators and calculation services. The company maintains active engagement through news updates, career opportunities, and multilingual content, indicating growth orientation and customer-centric operations. The presence of testimonials and detailed product information enhances credibility. While no explicit revenue data is available, the medium size and extensive product portfolio suggest a stable and established operation within the German manufacturing industry.

Security posture

The website employs HTTPS with a good SSL configuration, uses privacy-compliant cookie management via Borlabs Cookie, and avoids exposing sensitive data in its HTML content. However, the absence of explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No known vulnerabilities or outdated libraries were detected in the provided content. Incident response and vulnerability disclosure mechanisms are not publicly documented, which could be enhanced to improve security readiness and transparency. Overall, the security posture is good but could benefit from implementing additional best practices and formal incident response channels.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security policy or security.txt file to facilitate vulnerability reporting and improve incident response transparency.
  3. Regularly audit and update WordPress core and plugins to maintain security and performance.
  4. Enhance incident response readiness by providing clear contact channels for security issues.
  5. Continue to monitor and optimize privacy compliance, especially regarding cookie consent and data retention policies.

Technical notes

Notes

The website is built on a modern WordPress CMS platform, utilizing popular plugins such as Yoast SEO for search optimization, Borlabs Cookie for privacy management, and various UI enhancement tools like RoyalSlider and Accordion Slider. The use of jQuery and Google Maps API indicates a reliance on established JavaScript libraries. Performance optimizations are evident through WP Rocket caching and minification. The site is mobile responsive with dedicated CSS for tablets and smartphones. Accessibility features appear adequate, with semantic HTML and ARIA attributes used in navigation and forms. Hosting details are not explicitly identified, but DNS name servers suggest professional hosting. Overall, the technical infrastructure is robust, supporting a high-quality user experience and SEO performance.
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.
