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

GWS Ground Waterproofing Systems, s.r.o. is a Czech-based manufacturer specializing in ground waterproofing materials, thermal insulation, and construction geosynthetics. With over 25 years of experience, the company serves construction professionals and distributors across Europe, offering products such as hydro-insulation foils (PVC, HDPE, LDPE), thermal insulation materials (PAROC mineral wool, EPS, XPS, PIR), and additives for waterproof concrete. Their market position is that of a leading manufacturer in their niche, supported by a professional website and active social media presence. Technically, the website employs modern web technologies including jQuery, Bootstrap, Google Tag Manager, and Google Analytics, ensuring a responsive and user-friendly experience. The site is well-optimized for SEO and mobile devices, with a moderate performance profile. Privacy compliance is strong, featuring a comprehensive privacy policy, cookie consent mechanisms, and GDPR adherence. From a security perspective, the site uses HTTPS with good SSL configuration and implements Google reCAPTCHA for form protection. However, it lacks explicit security headers and published security policies or incident response contacts, which are areas for improvement. No vulnerabilities or exposed sensitive data were detected. Overall, the website is professional, trustworthy, and compliant with privacy regulations, though the absence of WHOIS data and domain registration details slightly reduces domain trustworthiness. Strategic recommendations include enhancing security headers, publishing security policies, and improving domain registration transparency.

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

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 sectors, focusing on waterproofing and insulation materials. Their business model centers on manufacturing and distributing specialized construction products to European markets. The company leverages modern production technologies and maintains a strong online presence to support sales and customer engagement. Their competitive advantage lies in their extensive experience, product quality, and comprehensive service offerings. The website indicates a medium-sized enterprise with clear contact channels and active social media engagement, suggesting a stable market position and growth potential. Partnerships with SEO and marketing firms indicate investment in digital marketing strategies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCAPTCHA to mitigate automated abuse. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No incident response or vulnerability disclosure information is published, which limits transparency and preparedness for security incidents. No exposed sensitive data or vulnerable libraries were detected, indicating good operational security hygiene. Overall, the security posture is good but could be enhanced by adopting additional best practices and publishing security policies.

Recommendations

  1. Implement HTTP security headers including Content Security Policy (CSP), HSTS, X-Frame-Options, and X-XSS-Protection to strengthen web security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance domain registration transparency by ensuring WHOIS data is complete and publicly accessible.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap (versions 4 and 5), Google Tag Manager, Google Analytics, and Google reCAPTCHA, indicating a modern and well-supported technology stack. The presence of AniJS and Nette Forms suggests custom interactive and form handling capabilities. Performance is moderate with room for optimization, especially given the use of multiple large libraries and scripts. Mobile optimization is good, with responsive design elements and mobile-friendly navigation. SEO is well addressed through meta tags, structured navigation, and content relevance. Accessibility is basic but could be improved with enhanced ARIA attributes and keyboard navigation support. Hosting provider details are not explicitly identified from the content.
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.
