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

Klober is a well-established UK-based manufacturer and supplier specializing in roofing ventilation products and roofing materials. As part of the BMI Group, Klober holds a leading market position in the roofing manufacturing sector, offering a comprehensive range of products including membranes, ventilation solutions, dry verge systems, and lead flashing alternatives. Their website targets installers, distributors, and roofing professionals, providing extensive product information, technical support, and training resources. The site is professionally designed with excellent content quality and clear navigation, reflecting a mature digital presence. Technically, the website employs modern JavaScript libraries such as jQuery, Swiper, and Bootstrap, ensuring a responsive and user-friendly experience across devices. The use of Google Tag Manager and reCAPTCHA indicates attention to marketing and security. While no explicit CMS is detected, the site demonstrates good SEO and accessibility practices. Performance is moderate, with opportunities for optimization. From a security perspective, the site enforces HTTPS and includes CSRF tokens, with a robust cookie consent mechanism supporting GDPR compliance.

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. 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.

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

Klober operates as a B2B supplier and manufacturer within the manufacturing sector, focusing on roofing ventilation and materials. Their competitive advantage lies in their comprehensive product range, technical expertise, and integration within the BMI Group, Europe's largest roofing manufacturer. Revenue streams likely include product sales, training services, and technical support. The target customer segments are installers, distributors, and roofing contractors primarily in the UK. Growth indicators include continuous product innovation, active customer communications, and a dedicated training platform. The partnership ecosystem includes BMI Group and related regional sites. The company demonstrates a strong market presence with consistent branding and professional outreach.

Security posture

The website exhibits a mature security posture with enforced HTTPS, CSRF protection, and a comprehensive cookie consent mechanism aligned with GDPR. The absence of explicit security headers in the HTML suggests an area for enhancement. No signs of malware, phishing, or exposed credentials were detected. The site uses Google reCAPTCHA to mitigate automated abuse. Incident response and security policy documents are not publicly available, indicating a potential compliance gap. Overall, the security maturity is good but could benefit from formalized policies and improved header configurations.

Recommendations

  1. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish explicit security policy and incident response documentation accessible to users and partners to improve transparency and compliance.
  3. Regularly audit and update third-party libraries and dependencies to mitigate vulnerabilities from outdated components.
  4. Enhance accessibility features to meet higher standards, improving usability for all users.
  5. Consider adding a terms of service page to clarify user agreements and legal protections.

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.
