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

Data Festival VŠE 2025 is an educational event website focused on workshops, lectures, and networking in the data science domain, likely organized by the University of Economics in Prague. The website targets students, professionals, and enthusiasts interested in data-related topics. The site is built on WordPress using the Divi theme and integrates common analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, and Facebook Pixel. The technical infrastructure is modern and mobile-optimized, though some accessibility features are basic. Security posture is moderate with HTTPS enabled but lacking visible security headers and formal security policies. Privacy and cookie policies are not found, indicating potential compliance gaps. The domain WHOIS data is unavailable, which limits trust analysis but may be due to registry privacy or policies. Overall, the website is professional and relevant to its audience but could improve in privacy compliance and security transparency.

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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 website serves as a platform for an educational event in the Czech Republic, focusing on data science and related fields. Its business model revolves around event organization and education, targeting a niche audience of students and professionals. The use of WordPress and Divi theme suggests a cost-effective and flexible approach to content management. The presence of multiple tracking and marketing tools indicates an intent to analyze visitor behavior and possibly retarget attendees. Lack of explicit business contact information and WHOIS data limits deeper business intelligence. The site appears to be a small-scale operation with a focus on delivering event-related content and networking opportunities.

Security posture

The website employs HTTPS, ensuring encrypted communication. However, no security headers such as Content-Security-Policy, X-Frame-Options, or Strict-Transport-Security were detected, which are recommended best practices. The absence of privacy and cookie policies suggests potential GDPR compliance issues. No incident response or vulnerability disclosure information is available. The use of third-party scripts introduces a moderate tracking footprint but no known vulnerabilities were identified in the provided data. Overall, the security posture is moderate but could be significantly improved by implementing security headers, formal policies, and incident response contacts.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a security.txt file to facilitate vulnerability disclosure and incident reporting.
  4. Provide clear contact information including emails and phone numbers for business and security inquiries.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with the Divi theme, leveraging plugins such as WP Job Manager and Divi Modules Table Maker. It uses Google Fonts for typography and integrates analytics and marketing tools including Google Tag Manager, Microsoft Clarity, and Facebook Pixel. The site is mobile-optimized and has good SEO meta tags including Open Graph and Twitter Cards. Performance is moderate, with asynchronous loading of scripts. Accessibility features are basic but present. The lack of visible security headers and formal privacy mechanisms indicates areas for technical improvement. Hosting provider details are not discernible from the 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.
