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

The website servisledobrazovek.cz represents a small Czech company, HDT impex s.r.o., specializing in the repair and maintenance of LED screens and panels for advertising, sports, and entertainment. The business operates a niche service model focused on professional servicing, reinstallation, software control, and expert consulting for LED display technology. The company has been established since 2012 and maintains a consistent online presence with related partner sites and social media channels. Technically, the website uses basic web technologies including jQuery 2.1.1 and the Coin Slider plugin, hosted on Forpsi servers. The site includes Google Analytics for visitor tracking but lacks modern CMS or frameworks. Performance and mobile optimization are basic, with limited accessibility features. SEO is minimally addressed through meta tags but lacks advanced structured data or Open Graph tags. From a security perspective, the site shows weaknesses including absence of HTTPS enforcement in the provided data, no visible security headers, and no privacy or cookie policies. Contact information is limited to a contact form without explicit email or phone contacts. The use of outdated JavaScript libraries and lack of security best practices present potential vulnerabilities. GDPR compliance is not evident, and no incident response or security policies are published. Overall, the website is functional for its business purpose but requires significant improvements in security, privacy compliance, and technical modernization to enhance trustworthiness and protect user data. Strategic recommendations include implementing HTTPS, adding privacy and cookie policies, updating technology stack, and improving security headers and form protections.

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

11 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

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 HDT impex s.r.o. holds a stable position in the Czech LED service market, focusing on LED screen repairs and maintenance. Their business model revolves around providing specialized technical services to businesses requiring LED display solutions. The presence of multiple related partner domains indicates a collaborative ecosystem enhancing their service offerings. The company targets commercial clients in advertising, sports, and entertainment sectors. Revenue streams likely derive from service contracts, consulting, and software support. Growth indicators are moderate given the domain age and consistent online presence. The partnership ecosystem includes LEDstudio and other LED technology providers, strengthening market reach and technical capabilities.

Security posture

The current security posture is basic and exhibits several gaps. The lack of HTTPS in the analyzed content is a critical issue that undermines data confidentiality and user trust. Absence of security headers such as Content-Security-Policy or X-Frame-Options increases exposure to common web attacks. No privacy or cookie policies are present, indicating non-compliance with GDPR requirements. The contact form lacks visible security controls like CAPTCHA or input validation. Use of outdated JavaScript libraries may expose the site to known vulnerabilities. Incident response readiness and security culture indicators are not evident. Overall, the site requires urgent security enhancements to protect business operations and customer data.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all website traffic.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Update JavaScript libraries to latest stable versions and audit for vulnerabilities.
  5. Enhance contact forms with CAPTCHA and input validation to prevent abuse.
  6. Establish an incident response plan and publish security contact information.
  7. Improve mobile responsiveness and accessibility to enhance user experience.
  8. Integrate structured data (JSON-LD) for better SEO and content discoverability.
  9. Regularly review and update external links and partner domain relationships.
  10. Consider adding explicit business contact details (email, phone, physical address) for transparency.

Technical notes

Notes

The website is built on a simple HTML structure enhanced with jQuery 2.1.1 and the Coin Slider plugin for image rotation. Google Fonts and Google Analytics are integrated for typography and analytics respectively. The hosting is managed via Forpsi, a Czech hosting provider, as indicated by the nameservers. The site lacks modern CMS or frameworks and does not use HTTPS in the provided content snapshot. Performance is moderate with asynchronous loading of analytics scripts but no advanced optimization techniques detected. Mobile optimization is basic with no explicit responsive design meta tags or viewport settings visible. Accessibility features are minimal, and SEO is limited to basic meta tags without Open Graph or JSON-LD structured data. The site would benefit from modernization including HTTPS adoption, responsive design, accessibility improvements, and enhanced SEO practices.
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.
