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.

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

  2. Security headers

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 holds a strong market position as an established non-profit with extensive experience and accreditation in volunteer coordination. Their business model focuses on community engagement and volunteer program development, targeting volunteers and beneficiaries in the Czech Republic and Europe. The website reflects a consistent brand and professional content quality, with key services including mentoring, sports volunteering, and cultural integration projects. Partnerships such as the external signup platform dcul.sinch.cz enhance operational capabilities. Growth indicators include active social media presence and ongoing project development. Revenue streams likely include grants, donations, and public funding typical for non-profits.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented ensuring encrypted communications. However, the absence of security headers like Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No visible vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or incident response contact limits transparency and preparedness for security incidents. GDPR compliance is incomplete due to missing privacy and cookie policies. Overall, the security posture is adequate but could be significantly improved with standard best practices and compliance measures.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit GDPR compliance statements.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish a security policy and provide clear incident response contact information (e.g., security@ or abuse@ email).
  4. Regularly audit and update WordPress core and plugins to mitigate vulnerabilities.
  5. Introduce a cookie consent mechanism to inform users and obtain consent for tracking.

Technical notes

Notes

The website is built on WordPress 6.8.3 with common plugins including Gutenberg, Carousel Block, and Advanced iFrame. It uses jQuery 3.7.1 and modern CSS for responsive and accessible design. Hosting is provided by WEDOS Internet, a.s., a reputable Czech hosting provider. Performance is moderate with optimized images and lazy loading. The site is mobile optimized and accessible with skip links and semantic HTML. SEO optimization is basic with meta tags and canonical links but lacks structured data like JSON-LD for enhanced search visibility. Technical risks are low but could be reduced further by implementing security headers and improving privacy compliance.
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.
