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

Sklopísek Střeleč, a. s. is a Czech-based medium-sized manufacturing company specializing in the supply of high-quality quartz sands for various industrial applications including glassmaking, foundry, filtration, and sports surfaces. The company positions itself as a reliable supplier with a focus on quality and availability, targeting industrial and commercial customers. The website reflects a professional business presence with clear product categorization and regular news updates, supporting its market position. Technically, the website employs a modern technology stack including jQuery, Bootstrap, and popular carousel libraries, along with analytics tools such as Google Analytics and Hotjar. The site is mobile-optimized and offers a good user experience with clear navigation and relevant content. However, some technical improvements could enhance accessibility and performance further. From a security perspective, the website uses HTTPS and avoids exposing sensitive data, but lacks important security headers and visible privacy and cookie policies, which are critical for GDPR compliance and user trust. No incident response or vulnerability disclosure information is provided, indicating room for improvement in security transparency and readiness. Overall, the website is functional and professional but would benefit from enhanced privacy compliance and security best practices to reduce risk and improve trustworthiness. Strategic recommendations include implementing privacy and cookie policies, adding security headers, and establishing a vulnerability disclosure process.

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.

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

The company operates in the manufacturing sector, focusing on quartz sand production and supply. Its business model is B2B, serving industries such as glassmaking, foundry, filtration, and sports surfaces. The website indicates a stable market presence with consistent branding and a focus on quality. The company supports local cultural events and maintains an active news section, suggesting community engagement. The lack of explicit financial or parent company data limits deeper business intelligence. The partnership with UVM interactive for website development indicates professional digital support. The company’s product segmentation and detailed categorization reflect a mature product offering and targeted marketing approach.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible sensitive data leaks. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. The lack of privacy and cookie policies indicates non-compliance with GDPR requirements, potentially exposing the company to regulatory risks. No incident response or vulnerability disclosure mechanisms are evident, which could delay response to security incidents. The use of third-party analytics and tracking tools like Google Analytics and Hotjar introduces privacy considerations that are not addressed transparently. Overall, the security maturity is basic and requires enhancements to meet modern standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy addressing GDPR compliance.
  2. Add a cookie consent banner and detailed cookie policy to inform users and obtain consent.
  3. Configure and deploy essential security headers (CSP, X-Frame-Options, X-Content-Type-Options).
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide clear incident response contact information to improve security transparency and readiness.

Technical notes

Notes

The website uses a custom CMS with a combination of jQuery, Bootstrap 3, and popular carousel plugins for UI components. It integrates Google Fonts and Google Analytics for typography and analytics respectively, along with Hotjar for user behavior tracking. The site is mobile responsive and has a moderate performance profile. However, the use of older Bootstrap 3 and jQuery versions may indicate some technical debt. Accessibility features are basic, and SEO is supported by proper meta tags and Open Graph data. There is no evidence of modern frontend frameworks or progressive web app features. Hosting details are not disclosed. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced security configurations.
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.
