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

TKF, spol. s r.o. is a leading Czech supplier specializing in event equipment sales and rental, including party tents, inflatable advertising products, flags, and furniture. The company offers comprehensive event services and solutions, targeting event organizers and businesses primarily in the Czech Republic. The website reflects a medium-sized enterprise with a professional online presence and a strong focus on customer service and product variety. Technically, the site employs modern web technologies such as Bootstrap, jQuery, and various marketing and analytics tools including Google Tag Manager and Tawk.to chat. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, the site uses HTTPS and cookie consent mechanisms, but lacks visible advanced security headers and explicit incident response or vulnerability disclosure information. The absence of WHOIS data reduces domain registration trust, but the website content and business information appear legitimate and consistent with a professional event equipment supplier. Overall, the site scores well in content quality, technical implementation, privacy compliance, and business credibility, with room for improvement in security posture and 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

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

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

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

TKF operates in the retail and hospitality sectors, focusing on event equipment sales and rentals. Their business model combines product sales with rental services and event consulting, serving a broad customer base including corporate clients and event organizers. The company demonstrates strong market positioning in the Czech Republic with a long tradition, supported by numerous references and partnerships. Their digital presence includes multilingual sites and active social media channels, enhancing customer reach. The company leverages third-party marketing and analytics tools to optimize customer engagement. However, the lack of publicly available WHOIS data and security policy details suggests areas for operational transparency improvement. The partnership ecosystem includes related domains for English and German language markets, indicating regional expansion or service diversification.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and cookie consent implemented, indicating compliance with GDPR requirements. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure information is provided, which limits transparency and preparedness for security incidents. The use of multiple third-party scripts introduces potential risk vectors that require regular auditing. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. Overall, the security maturity is adequate for a medium-sized retail business but could be enhanced by implementing stronger security headers, publishing security policies, and establishing a vulnerability disclosure program.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against web attacks.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and customer trust.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerabilities.
  5. Obtain and publish accurate WHOIS domain registration data to improve domain trustworthiness and legitimacy.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Bootstrap, Lightbox, and Owl Carousel for UI components and interactivity. Google Tag Manager and Google Analytics are employed for tracking and marketing analytics, alongside Leady and Optimonk for lead generation and onsite marketing. The site is mobile-optimized with responsive design and includes accessibility features at a basic level. Performance is moderate, with asynchronous loading of scripts to improve page load times. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not discernible from the HTML content. The site includes multiple external resources and social media integrations, which enhance functionality but require careful security management. Overall, the technical infrastructure supports a professional and user-friendly website suitable for the company's business needs.
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.
