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

TSC Group is a prominent holding company based in the Czech Republic, specializing in a broad range of facility management and technical services including cleaning, laundry, technological cleaning, and paint stripping. The group oversees 12 subsidiaries, serving diverse sectors such as industrial manufacturing, healthcare, administrative offices, and outdoor maintenance. Their market position is strong as the largest group in their sector within the Czech Republic, supported by certifications like ISO 50001 and EcoVadis, and partnerships with notable sports clubs. The website reflects a professional and comprehensive digital presence with clear service offerings and strong branding consistency. Technically, the website employs modern web technologies including Google Tag Manager, Swiper.js for UI components, and the Nette framework for form validation. The site is mobile-optimized with good performance and SEO practices. Security measures include HTTPS enforcement, use of reCaptcha on forms, and a cookie consent mechanism compliant with GDPR. However, some recommended security headers like Content-Security-Policy and X-Frame-Options are not explicitly confirmed and could be improved. Overall, the security posture is solid with no visible vulnerabilities or exposed sensitive data. The absence of WHOIS data limits domain registration insights, but the professional presentation, certifications, and subsidiary network strongly indicate legitimacy and trustworthiness. The website content is safe for general audiences, with no adult or questionable material detected. Strategically, TSC Group should focus on enhancing security headers, maintaining GDPR compliance, and continuing to leverage their strong market position and certifications to build trust and expand their service offerings.

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

8 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

TSC Group operates as a holding company managing a portfolio of subsidiaries that provide integrated facility management and technical services. Their competitive advantage lies in their scale, technological investment, and comprehensive service range covering industrial, healthcare, and administrative sectors. Revenue streams likely derive from long-term contracts with industrial clients, healthcare institutions, and commercial properties. The company targets large enterprises requiring complex facility solutions. Growth indicators include recent certifications, expansion of subsidiaries, and active partnerships with sports organizations. The partnership ecosystem is robust, supporting brand visibility and community engagement. Operationally, the group emphasizes innovation with high-tech cleaning methods and RFID tracking, positioning them as a market leader in the Czech Republic.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCaptcha to protect forms from abuse. Cookie consent mechanisms align with GDPR requirements, indicating attention to privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit Content-Security-Policy and other security headers suggests room for improvement. Incident response and security policy information are not publicly disclosed, which is common but could be enhanced for transparency. Overall, the security maturity is good for a commercial website, with recommendations to strengthen header policies and maintain regular security audits.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  4. Maintain and update GDPR compliance documentation and cookie consent mechanisms as regulations evolve.
  5. Leverage certifications and partnerships in marketing to reinforce business credibility and customer confidence.

Technical notes

Notes

The website is built using modern web technologies including HTML5, CSS3, JavaScript, and frameworks such as Nette for backend form validation. Google Tag Manager is used for analytics and marketing tags, and Swiper.js provides interactive UI components. The site is mobile responsive and optimized for user experience with fast loading times. There is no detected CMS, suggesting a custom or framework-based implementation. Hosting provider details are not disclosed. Performance is moderate with good SEO and accessibility basics in place. Opportunities exist to improve accessibility and implement advanced security headers to reduce technical risks.
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.
