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

Tuesday.cz is a Czech-based company specializing in organizing professional events ranging from training sessions to large full-day conferences, both online and offline. The website targets professionals seeking educational and networking opportunities in their respective fields. The business operates in the education sector with a focus on event management and training services. The website presents a professional design with consistent branding and relevant content, although it lacks explicit contact details and comprehensive privacy documentation. Technically, the website employs modern web technologies including Google Tag Manager, Google Analytics, and Facebook Pixel for marketing and analytics purposes. The site is mobile-optimized and performs moderately well, but there is room for improvement in accessibility and SEO. Security measures include HTTPS enforcement and frame busting scripts, but the absence of security headers and vulnerability disclosure mechanisms suggests potential gaps in security maturity. The security posture is adequate but could be enhanced by implementing recommended headers and publishing clear privacy and terms policies. The lack of WHOIS data due to privacy protection slightly reduces trustworthiness but is understandable for a small business. Overall, the site is safe for general audiences and does not contain any adult or questionable content. Strategic recommendations include enhancing privacy compliance, improving security headers, publishing contact and incident response information, and establishing a vulnerability disclosure policy to strengthen trust and security culture.

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.

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

Tuesday.cz operates in a niche market within the Czech Republic, focusing on professional education through events and conferences. Its business model revolves around organizing and hosting specialized training and networking opportunities for professionals. The company leverages digital marketing tools to reach its audience but lacks visible certifications or trust badges that could enhance credibility. The absence of detailed company registration or VAT information limits transparency. Growth potential exists through expanding event offerings and improving digital presence. Partnerships with payment processors or event platforms are not explicitly identified in the data.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, which is essential for secure communications. However, the lack of security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options indicates room for improvement. No evidence of exposed sensitive data or vulnerable libraries was found, but the absence of a security.txt file or incident response contacts suggests limited preparedness for security incidents. Cookie consent mechanisms are implemented, indicating some level of privacy awareness. Overall, the security posture is functional but should be enhanced to meet higher compliance and protection standards.

Recommendations

  1. Implement comprehensive privacy and terms of service pages to improve legal compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen security posture.
  3. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting and response.
  4. Enhance accessibility features to improve usability for all users and comply with accessibility standards.
  5. Increase transparency by providing explicit contact information including company emails and phone numbers.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Google Analytics, Facebook Pixel, and asynchronous JavaScript loading for performance optimization. Fonts are loaded via Google Fonts with cookie consent tracking. The site is mobile responsive and uses SVG sprites for icons, indicating attention to performance and design. However, no CMS or hosting provider information was detected. Performance is moderate with potential for improvement in loading speed and accessibility compliance. SEO is supported by proper meta tags and Open Graph data, enhancing social media sharing and search engine visibility.
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.
