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

Nadace Sirius is a Czech private non-profit foundation established in 2008, dedicated to improving the lives of disadvantaged children through grant programs, social projects, and direct aid. The foundation is led and fully funded by Radka and Jiří Šmejc and collaborates with various organizations and events to support child welfare. The website is professionally designed using Joomla CMS and modern web technologies, providing clear navigation and rich content primarily in Czech. It includes a cookie consent mechanism and uses analytics tools such as Google Analytics and Microsoft Clarity. Security posture is good with HTTPS enforced, though security headers are missing and no explicit privacy policy page was found. WHOIS data is unavailable, likely due to privacy protection, which slightly reduces trust but is common for non-profits. Overall, the site is trustworthy, well-maintained, and focused on social impact.

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

7 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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.

Dark web exposure

Add-on

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The foundation operates in the non-profit sector focusing on child protection, family support, substitute family care, and children with disabilities. It funds and implements projects, organizes conferences, and runs grant programs. The target audience includes social workers, educators, families, and other non-profits. The foundation maintains a clear brand and consistent messaging. Its partnerships include OPS Sirius and Centrum Podpory. The website supports transparency with detailed project information and contact details. The business model relies on private funding and grantmaking. Growth indicators include active project updates and events. The foundation holds a stable market position within Czech social services.

Security posture

The website enforces HTTPS and uses cookie consent with granular user control, reflecting good privacy practices. It employs Google Tag Manager and analytics tools responsibly. However, the absence of security headers like Content-Security-Policy and X-Frame-Options is a gap. No security or incident response policies are publicly disclosed, and no vulnerability disclosure mechanism is present. WHOIS data is not available, which is common for privacy-protected domains but reduces transparency. Overall, the security posture is solid but could be improved by adding security headers, publishing privacy and security policies, and implementing a vulnerability disclosure process.

Recommendations

  1. Add and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a comprehensive privacy policy page clearly linked from the homepage to improve GDPR compliance and user trust.
  3. Implement a security.txt file or vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Regularly audit and update Joomla CMS and all plugins to mitigate risks from known vulnerabilities.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on Joomla CMS with Bootstrap and jQuery frameworks, using Smart Slider 3 for interactive content. It integrates Google Tag Manager, Google Fonts, and CookieHub for cookie management. The site loads moderately fast and is mobile-optimized with responsive design. Accessibility is basic but could be improved. SEO is supported with proper meta tags and structured navigation. Hosting provider details are not evident. The site uses multiple external analytics and marketing domains, indicating extensive user tracking but with user consent. Technical debt appears low, but security headers are missing, representing a modernization opportunity.
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.
