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

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 22 days

      What to do: Renew SSL certificate before expiration

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 business operates in the hospitality sector, focusing on ticket sales for cultural events. Its market positioning as the largest event ticket provider in the Pilsen region suggests a strong local presence and competitive advantage. The business model revolves around online ticket sales and event promotion, likely generating revenue through ticket commissions or sales fees. The target customer segment includes culture enthusiasts, tourists, and local residents. The presence of a dedicated reservation subdomain indicates a structured approach to service delivery. The company leverages partnerships with advertising and analytics providers such as Google and Facebook to enhance marketing effectiveness. Growth indicators include a long domain age and consistent branding. Strategic observations suggest opportunities to enhance direct contact availability and publish security policies to further build trust.

Security posture

The website exhibits a mature security posture with HTTPS enabled and a comprehensive cookie consent mechanism that aligns with GDPR requirements. The use of Cookiebot ensures granular user consent management and transparency about cookie usage. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy are not explicitly identified in the provided data and should be verified and implemented if missing. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and security policy documentation are absent from the visible content, representing a compliance gap. Overall, the security maturity is good but can be improved by formalizing security policies and incident response procedures.

Recommendations

  1. Implement and verify comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  2. Publish a dedicated security policy and incident response plan accessible from the website.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Enhance contact information visibility, including dedicated security and abuse contact channels.
  5. Continue monitoring third-party scripts and update dependencies regularly to mitigate potential vulnerabilities.

Notes

The website is built on a modern React/Next.js framework, leveraging server-side rendering for performance and SEO benefits. It uses DatoCMS for content management, which supports structured content delivery. Integration with Google Tag Manager and Facebook Pixel indicates advanced marketing and analytics capabilities. Cookiebot is used for GDPR-compliant cookie management. Hosting is provided by REG-WEBGLOBE, a reputable registrar and hosting provider. Performance is moderate, with good mobile optimization and basic accessibility features. The site uses multiple CSS and JavaScript chunks for modular loading. There is an opportunity to improve accessibility and performance by auditing and optimizing resource loading and enhancing ARIA attributes.
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.
