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

OLDstars is a Czech student theater group that organizes theatrical performances, festivals, and acting courses primarily in Prague and surrounding regions. Their website showcases a rich program of upcoming performances, news, and educational opportunities, targeting students and theater enthusiasts. The site is built on modern web technologies such as Next.js and React, providing a responsive and user-friendly experience. Security posture is good with HTTPS and some security best practices, though some HTTP security headers could be improved. Privacy and cookie policies are not clearly presented, which is a compliance gap. WHOIS data is unavailable, which reduces domain trust but the professional content and social media presence support legitimacy. Overall, the site is a well-maintained cultural platform with room for enhanced privacy 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

10 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 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

OLDstars operates in the cultural and educational sector focusing on student theater productions and festivals. Their business model appears to be non-profit or community-oriented, relying on grants, partnerships, and ticket sales through platforms like Goout. They have a strong local presence in Prague and the Czech Republic with partnerships with theaters and cultural institutions. The organization engages youth through acting courses and workshops, indicating a focus on talent development and community engagement. Their marketing leverages social media and event platforms effectively. The lack of WHOIS data is a minor concern but does not detract significantly from their market position as a reputable cultural entity.

Security posture

The website uses HTTPS with a valid SSL certificate and includes Google Tag Manager for analytics. Security headers such as HSTS are likely present, but others like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly detected and should be implemented to enhance security. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of a security policy or incident response contact reduces transparency. Overall, the security posture is good but could be improved with additional headers and documented policies.

Recommendations

  1. Implement a comprehensive privacy policy and make it easily accessible on the website.
  2. Add a cookie policy with a consent mechanism to comply with GDPR and other privacy regulations.
  3. Enhance HTTP security headers by adding Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Investigate and resolve the lack of WHOIS data or consider domain registrar update to improve domain legitimacy.

Technical notes

Notes

The website is built using Next.js, a React framework, indicating a modern and scalable architecture. It uses Font Awesome for icons and Google Tag Manager for analytics. The site is mobile optimized and loads multiple images responsively. The HTML is well structured with meta viewport tags for responsiveness. Performance is moderate, with preloading of CSS and scripts. No CMS is explicitly detected, suggesting a custom or framework-based solution. Hosting provider details are not disclosed. Accessibility is basic but could be improved with ARIA roles and landmarks. SEO is good with descriptive titles and structured navigation.
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.
