57/100

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

The website brnoopen.eu serves as the official platform for the BRNO OPEN 2023 dance sport event, specifically hosting the WDSF World Championships in Latin and Showdance Standard categories. The site targets dance sport enthusiasts, competitors, and attendees primarily in the Czech Republic. The business model revolves around event organization and promotion within the niche of competitive dance sport. Technically, the site is built on WordPress using the Divi theme, leveraging modern web fonts and structured data for SEO. Performance and mobile optimization are adequate, though accessibility features are basic. Security posture is limited, with no evident security headers or policies, and privacy compliance is minimal due to the absence of privacy and cookie policies. The domain registration is consistent with the business location and nature, registered through a reputable Czech registrar, ZONER a.s. Overall, the site is professional and relevant but would benefit from enhanced security and compliance measures.

NIS2 and GDPR posture

Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

BRNO OPEN 2023 positions itself as a specialized event organizer in the dance sport industry, focusing on world championship-level competitions. Its competitive advantage lies in hosting prestigious WDSF events in Brno, attracting a targeted audience of dancers and fans. The business model is event-centric, likely generating revenue through registrations, sponsorships, and ticket sales. The website content is tailored to inform and engage participants and spectators. The partnership ecosystem is not explicitly detailed on the site. Growth indicators include scheduled events for 2025, suggesting ongoing activity and planning. Strategic observations highlight the need for improved digital trust signals and compliance documentation to support business credibility.

Security posture

The current security maturity level of the website is low. Key vulnerabilities include the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are critical for mitigating common web attacks. There is no visible privacy policy or cookie consent mechanism, indicating compliance gaps with GDPR and related regulations. Incident response readiness is not addressed, with no security contact information provided. Data protection practices appear minimal, and no vulnerability disclosure or security.txt files are present. The security culture seems undeveloped, which could expose the organization to reputational and operational risks. Business impact of these gaps includes potential legal non-compliance and increased susceptibility to cyber threats.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers to the web server configuration to enhance protection against common web vulnerabilities.
  3. Establish and publish incident response and vulnerability disclosure contacts, including security@ or abuse@ email addresses.
  4. Provide clear and accessible contact information for general and security inquiries to improve trust and communication.
  5. Conduct a security audit to identify and remediate any underlying vulnerabilities and improve overall security posture.

Technical notes

Notes

The website is built on a widely used CMS platform, WordPress, with the Divi theme, indicating a modern and flexible technical infrastructure. The use of Google Fonts and JSON-LD structured data demonstrates attention to SEO and user experience. Hosting is provided by ZONER a.s., a reputable Czech provider. Performance is moderate, with no explicit indicators of slow loading or technical debt. Mobile optimization is good, ensuring accessibility across devices. However, accessibility features are basic and could be enhanced to meet broader standards. The absence of advanced security configurations and compliance documentation suggests areas for modernization and risk mitigation. Overall, the technical setup supports the business needs but requires improvements in security and compliance to align with best practices.
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.
