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

Event Service, s.r.o. is a Czech Republic-based sports marketing agency providing a broad range of services including strategic consulting, online communication, event organization, and digital marketing. They also operate Týmuj.cz, a popular online platform for sports team management used by thousands in Czechia and Slovakia. The company targets sports teams, athletes, and businesses seeking sports marketing solutions, positioning itself as a regional player with a professional online presence. Technically, the website uses standard web technologies such as jQuery and Google Analytics, with moderate performance and good mobile optimization. However, the absence of WHOIS data and lack of visible security headers present concerns regarding domain legitimacy and security posture. Privacy compliance is weak due to missing privacy and cookie policies, and no explicit GDPR indicators are present. Overall, the site is professional and content-rich but requires improvements in security and compliance to enhance trust and reduce risk.

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

10 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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 media sector focusing on sports marketing and digital communication. Its business model combines service provision with platform operation (Týmuj.cz). The website showcases client logos indicating established partnerships, enhancing credibility. The target market includes sports teams and companies in Czechia and Slovakia. The lack of WHOIS data is unusual and may warrant further investigation. The company appears small-sized with a focused regional presence. Marketing tools and analytics are used moderately, but transparency and compliance could be improved. The business ecosystem includes the Týmuj.cz platform as a key asset, supporting user engagement and recurring usage.

Security posture

The website uses HTTPS and secure form submission but lacks important security headers such as Content Security Policy, HSTS, and X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No incident response or security contact information is provided. The WHOIS data absence reduces trust in domain legitimacy. Overall, the security posture is moderate but requires enhancements in headers, privacy compliance, and transparency to meet best practices and regulatory requirements.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Verify and update WHOIS domain registration information to ensure transparency and trust.
  4. Enhance accessibility features and conduct regular security audits of JavaScript libraries and dependencies.
  5. Provide explicit incident response and security contact information to improve security culture and readiness.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS3, and jQuery 1.11.2. It uses Google Analytics and Google Tag Manager for tracking and analytics. The site is mobile responsive with good navigation and SEO meta tags. However, the use of an older jQuery version may pose security risks if not updated. No CMS or hosting provider information is evident. Performance is moderate with no major issues detected. Accessibility is basic and could be improved. The absence of security headers and privacy compliance features indicates technical debt in security and regulatory adherence.
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.
