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

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 organization operates a trusted helpline service with a clear focus on child and youth welfare. Its business model relies on donations and partnerships with government ministries and foundations. The website reflects a mature digital presence with a focus on transparency, community engagement, and impact storytelling. The partnership ecosystem includes key Czech ministries and financial institutions, enhancing credibility and funding stability. The target audience includes children, youth, and supporters interested in child protection and mental health.

Security posture

The website employs HTTPS with a valid SSL configuration and uses secure forms with CSRF tokens. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. No vulnerability disclosure or security policy is published, and no incident response contacts are provided. Tracking technologies are used moderately, including Facebook Pixel and LinkedIn Insight, without explicit cookie consent mechanisms, indicating room for privacy compliance improvement.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance web security.
  2. Add an explicit cookie consent banner to comply with GDPR and improve user privacy transparency.
  3. Publish a security policy and incident response contact information to improve trust and readiness.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly review and update privacy and cookie policies to reflect current data collection and processing practices.

Technical notes

Notes

The website uses modern front-end technologies including Alpine.js and integrates multiple tracking and analytics services via Google Tag Manager. The site is mobile-optimized with responsive design and good SEO practices. Hosting appears stable with Czech-based registrar and name servers. Performance is moderate, with potential improvements in accessibility and loading speed. No CMS is explicitly detected, suggesting a custom or static site architecture. Technical debt is low, but security header implementation and privacy compliance could be enhanced.
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.
