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

Klöber GmbH is a well-established German manufacturer specializing in innovative roofing accessories for pitched and flat roofs, serving primarily B2B customers such as roofing professionals, architects, and distributors. The company boasts over 60 years of experience and holds recognized certifications like ISO 9001 and ISO 14001, reinforcing its market position as a leading specialist in Europe. The website reflects a mature digital presence with comprehensive product information, configurators, and resource centers, supporting customer engagement and technical support. Technically, the website employs modern web technologies including Bootstrap, jQuery, Swiper, and Google reCAPTCHA, ensuring responsive design and security against spam. The site is well-optimized for mobile devices and SEO, with clear navigation and professional design. Security practices include HTTPS enforcement and CSRF tokens, although some HTTP security headers could be improved. Privacy compliance is robust, featuring detailed cookie consent mechanisms and a comprehensive privacy policy. The security posture is strong with no evident vulnerabilities or exposed sensitive data. However, the absence of a public security policy or incident response contact is noted. The domain WHOIS data aligns well with the business claims, showing consistent registration and no privacy protection, which supports legitimacy. Overall, the website is trustworthy, professional, and secure, with minor areas for enhancement in security headers and incident response transparency. Strategically, Klöber should focus on publishing a formal security policy and incident response contacts, enhancing HTTP security headers, and maintaining their strong privacy compliance to further build customer trust and meet evolving regulatory requirements.

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

2 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

  2. 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

Klöber GmbH operates in the manufacturing sector, focusing on roofing accessories and components. Its competitive advantage lies in its long-standing market presence, comprehensive product portfolio, and certifications that assure quality and environmental standards. The business model is B2B, targeting roofing contractors, architects, and distributors across Europe, especially Germany. Revenue streams likely include product sales, configurator services, and technical support. The company maintains a strong partnership ecosystem with related configurator domains and regional sites. Growth indicators include active content updates, configurator tools, and multi-language support. Operationally, Klöber leverages digital tools for customer engagement and product information dissemination, positioning itself as a trusted industry leader.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, CSRF tokens in forms, and integration of Google reCAPTCHA v3 to mitigate spam and bot activity. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No public security policy or incident response contact information is available, which could hinder vulnerability reporting and incident management. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is good but could be improved by adopting additional HTTP headers and publishing security policies.

Recommendations

  1. Publish a formal security policy and incident response contact information on the website.
  2. Implement HTTP security headers including Content Security Policy (CSP), HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Maintain and regularly update cookie consent mechanisms to ensure ongoing GDPR compliance.
  4. Conduct periodic security audits to identify and remediate potential vulnerabilities.
  5. Enhance transparency by providing a security.txt file to facilitate responsible vulnerability disclosure.

Overall, the infrastructure supports a professional and user-friendly experience aligned with business needs.
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.
