Medium risk. 5 critical or high findings in GDPR outside view.

Risk levelMedium

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

Tuesday.cz is a Czech website positioning itself as a social network in the real world, primarily focused on organizing professional events such as trainings and full-day conferences, both online and offline. The site targets professionals interested in educational and networking events. The technical infrastructure includes common web technologies and third-party analytics and advertising tools, but lacks visible advanced frameworks or CMS identification. Security posture is moderate with no detected security headers and unknown SSL configuration. Privacy compliance is weak due to absence of visible privacy and cookie policies. The lack of WHOIS data reduces trustworthiness and raises concerns about domain legitimacy. Overall, the website appears functional and professional but would benefit from improved transparency and security practices.

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

The business model revolves around event organization and social networking for professionals, offering a range of services from trainings to large conferences. The target audience is likely professionals and companies seeking educational opportunities. The website uses multiple advertising and tracking services, indicating a monetization strategy involving ads and possibly event promotion. The absence of detailed company information and contact data limits the ability to fully assess market positioning and partnerships. The site appears to be a small-scale operation focused on the Czech market.

Security posture

Security maturity is moderate but with notable gaps. The site uses HTTPS (assumed from canonical URLs), but no security headers were detected in the provided data. There is no visible privacy policy or cookie consent mechanism, which is a compliance risk under GDPR. No incident response or vulnerability disclosure information is present. The use of multiple third-party scripts increases the attack surface. Recommendations include implementing security headers, publishing privacy and cookie policies, and establishing clear incident response channels.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish WHOIS information or ensure domain registration details are accessible to improve trust.
  4. Establish and publicize incident response and vulnerability disclosure procedures.
  5. Audit third-party scripts regularly to minimize security risks and improve performance.

Technical notes

Notes

The website uses standard web technologies including JavaScript, CSS, Google Tag Manager, Google Analytics, and Facebook Pixel. Fonts are loaded via Google Fonts with cookie consent tracking. The site appears mobile optimized and has a good design quality. However, no CMS or advanced frameworks were identified. Performance is moderate with asynchronous loading of scripts. Accessibility features are basic, and SEO optimization is good with proper meta tags and Open Graph data. Hosting provider and SSL configuration details are not available from the provided data.
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.
