Technically, the website employs modern web technologies such as Bootstrap, jQuery, Google Tag Manager, and Google Analytics, ensuring a responsive and user-friendly experience. The site is well-optimized for mobile devices and includes accessibility features, though some improvements could be made. Security measures include HTTPS enforcement, reCAPTCHA integration, and a comprehensive cookie consent mechanism, indicating a mature approach to user privacy and data protection. From a security perspective, the site demonstrates good practices but lacks explicit HTTP security headers and a public security policy or incident response contact. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data for the domain is a concern, reducing trustworthiness and suggesting the need for further verification of domain registration status. Overall, the website is professional, trustworthy, and compliant with GDPR requirements, with clear contact information and active social media presence. Strategic recommendations include enhancing security headers, publishing a vulnerability disclosure policy, and verifying domain registration details to improve trust and 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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

GWS operates in the manufacturing and construction materials sector, focusing on waterproofing and insulation products. Their competitive advantage lies in their extensive experience, product quality, and technological capabilities. The business model is primarily B2B, serving construction companies and distributors. Revenue streams likely include product sales and custom solutions. The company shows growth potential through innovation and modular construction technologies. Partnerships with industry players and active social media engagement support their market presence. The website content and structure reflect a stable and established operation with a focus on quality and customer service.

Security posture

The website exhibits a mature security posture with HTTPS enforced and integration of Google reCAPTCHA to protect forms. Cookie consent mechanisms comply with GDPR, providing users control over tracking preferences. However, the lack of HTTP security headers such as Content Security Policy and HSTS is a gap that could be exploited. No security.txt or incident response information is publicly available, which limits transparency for vulnerability reporting. No signs of vulnerabilities or data leaks were found in the content. Overall, the security posture is good but could be improved with additional headers and published policies.

Recommendations

  1. Implement HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and facilitate vulnerability reporting.
  3. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  4. Enhance website accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Verify and publish domain registration details to improve trustworthiness and address the missing WHOIS data issue.

Technical notes

Notes

The website uses a combination of Bootstrap 4 and 5, jQuery, Google Tag Manager, Google Analytics, and reCAPTCHA, indicating a modern and well-supported technology stack. Performance is moderate with room for optimization. The site is mobile responsive and SEO optimized with proper meta tags and structured navigation. Accessibility is basic but functional. No CMS was detected, suggesting a custom or static site architecture. Hosting provider details are not evident from the content. Technical risks are low, but the mixed use of Bootstrap versions and multiple analytics scripts could be streamlined for better performance and maintainability.
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.
