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

3 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 is positioned as a key player in the Czech ticketing software market, leveraging over 20 years of experience and a team of experts in development, analytics, hardware, and support. Their business model focuses on B2B services, providing tailored solutions for various cultural institutions and events. Revenue streams likely include software licensing, hardware sales, support contracts, and marketing services. The partnership with ColosseumTicket.cz extends their market reach into ticket sales. The website content and structure indicate a focus on customer engagement and service transparency. Growth indicators include active career pages and marketing efforts. The company maintains a professional ecosystem with social media presence and structured data for SEO benefits.

Security posture

The website employs HTTPS with a valid SSL certificate, uses Google reCAPTCHA to protect forms, and implements a cookie consent banner compliant with GDPR. However, no explicit security headers (such as Content Security Policy, X-Frame-Options, or HSTS) were detected, which could enhance protection against common web attacks. There is no publicly available security policy or incident response information, which limits transparency in handling security events. No vulnerabilities or exposed sensitive data were found in the analysis. The security score is good but can be improved by adopting additional best practices and publishing security-related policies.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a clear security policy and incident response plan accessible to users and partners.
  3. Add a terms of service page to clarify user agreements and legal protections.
  4. Regularly audit and update third-party plugins and libraries to mitigate vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on WordPress CMS using Elementor for page building and Yoast SEO for search engine optimization. It uses Bootstrap 4 for responsive design and jQuery for scripting. Google Fonts and Google reCAPTCHA are integrated for typography and security respectively. The site loads multiple CSS and JS assets, including Slider Revolution for sliders. Performance is moderate with room for optimization. Mobile responsiveness is good, and SEO is well addressed with meta tags and structured JSON-LD data. Accessibility is basic but could be improved. Hosting provider details are not explicitly found. Overall, the technical infrastructure is modern and suitable for the business needs but could benefit from performance tuning and enhanced security configurations.
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.
