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

EVENT ARENA s.r.o. is a Czech-based event management company specializing in organizing corporate events such as conferences, VIP events, virtual events, and teambuilding activities. The company has a strong market presence supported by numerous awards and a broad client portfolio including major corporations. Their website reflects a professional and modern digital presence with multimedia content and clear navigation. Technically, the site uses modern tracking and video technologies, though some security best practices like security headers are missing. Privacy compliance is partially addressed with a cookie consent mechanism but lacks a dedicated privacy policy page. Overall, the security posture is moderate with room for improvement in transparency and technical safeguards. The domain WHOIS data is missing, which reduces trustworthiness but the business information on the site is consistent and credible.

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

6 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

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

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 targets corporate clients seeking comprehensive event organization services in the Czech Republic. Their business model focuses on full-service event planning and execution, including virtual and hybrid events, brand launches, and incentive programs. The presence of multiple client logos and industry memberships indicates strong partnerships and a reputable market position. The website content and awards suggest a medium-sized enterprise with a focus on innovation and customer experience. The lack of WHOIS data is a notable gap but does not contradict the business's apparent legitimacy. The company leverages digital marketing tools and tracking to optimize outreach and client engagement.

Security posture

The website employs HTTPS and cookie consent mechanisms, indicating baseline security awareness. However, the absence of visible security headers and no published security or incident response policies highlight gaps in security maturity. No vulnerabilities or exposed sensitive data were detected in the content. The lack of a privacy policy and incident response contact reduces compliance with GDPR and best practices. Overall, the security posture is moderate but could be enhanced by implementing security headers, publishing privacy and security policies, and providing clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add explicit incident response and security contact information on the website.
  4. Regularly audit and update third-party scripts and tracking tools to mitigate vulnerabilities.
  5. Enhance transparency by publishing terms of service and data protection officer contact details.

Technical notes

Notes

The website uses a modern tech stack including Video.js for media playback, Google Tag Manager for analytics, and Leady for marketing tracking. The site is mobile responsive with good design quality and clear navigation. Performance is moderate with some potential for optimization. No CMS was explicitly detected, suggesting a custom or static site build. Hosting provider details are not available. Accessibility features are basic but present. SEO is well addressed with proper meta tags and structured content. Technical risks include missing security headers and reliance on third-party tracking scripts without visible mitigation details.
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.
