Risk levelMedium

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

The website represents a small non-profit organization dedicated to the restoration of Katzelsdorfský zámeček, a cultural heritage site in the Czech Republic. The organization provides information and community engagement related to this restoration effort. The site is built on the Webnode CMS platform and uses standard web technologies including HTTPS, Google Analytics, and Facebook SDK for social media integration. The technical infrastructure is moderate with CDN hosting and basic mobile optimization. Security posture is adequate with HTTPS enabled and IP anonymization in analytics, but lacks important security headers and privacy policies, indicating room for improvement in compliance and security best practices. Overall, the website is functional and trustworthy for its niche audience but would benefit from enhanced privacy and security measures.

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

8 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

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 as a non-profit association focused on cultural heritage restoration, targeting local and international audiences interested in historical preservation. Its business model is community and donation-driven, with no commercial sales evident. The website's market position is niche and localized, with limited digital marketing or advertising presence. The presence of a Facebook page and YouTube video indicates some engagement with social media. The lack of detailed business data and WHOIS transparency is typical for small non-profits. The organization appears to maintain a modest but credible online presence with clear contact information and a consistent brand image.

Security posture

The website demonstrates a basic security posture with HTTPS enforced and anonymized IP tracking in Google Analytics. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important for mitigating common web vulnerabilities. No forms collect sensitive personal data beyond a basic search function, reducing risk exposure. The absence of privacy and cookie policies is a compliance gap, especially under GDPR regulations applicable in the Czech Republic. No incident response or security contact information is provided, limiting transparency in case of security events. Overall, the security maturity is low to moderate, suitable for a small non-profit but requiring improvements to align with best practices.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common attacks.
  3. Provide clear incident response contact information to improve transparency and readiness.
  4. Regularly audit third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built on the Webnode CMS platform, leveraging Cloudfront CDN for content delivery. It uses Google Analytics for visitor tracking with IP anonymization and Facebook SDK for social media integration. The site loads JavaScript and CSS from CDN sources, indicating a modern approach to performance optimization. However, the site lacks advanced SEO meta tags and accessibility features. The mobile optimization is basic, and the site design is simple but functional. No advanced frameworks or platforms beyond the CMS and standard libraries are detected. Performance is moderate, with no evident critical technical debt but opportunities for modernization and improved security hardening.
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.
