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

Svépomocná společnost Mlýnek, z. s. is a small non-profit organization based in Ostrava, Czech Republic, dedicated to supporting individuals with mental illness. The organization focuses on enabling these individuals to lead meaningful and active lives within their natural environment through various supportive activities and services. The website reflects this mission with clear, relevant content and a consistent brand presence. Technically, the site is built on the Webnode CMS platform, hosted via AWS Cloudfront CDN, and uses Google Tag Manager for analytics. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. Security-wise, the website enforces HTTPS and uses Google Tag Manager but lacks important security headers and explicit privacy and terms of service documentation.

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

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 in the non-profit sector, targeting persons with mental illness and their communities in the Ostrava region. Its business model centers on providing social support and community services rather than commercial activities. The website positions the organization as a local support entity with a focus on respect, safety, and trust-building. The use of Webnode CMS and AWS Cloudfront indicates a cost-effective and scalable digital infrastructure. The presence of Google Tag Manager suggests some level of digital marketing and analytics maturity. However, the lack of detailed contact information and absence of privacy and terms policies may limit trust and user engagement. The organization does not appear to have subsidiaries or partnerships listed on the site. Growth opportunities could include enhancing transparency, adding detailed contact and compliance information, and improving security measures.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options reduces protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Google Tag Manager is standard but requires proper configuration to avoid privacy issues. The lack of explicit privacy policy and incident response contact information indicates gaps in compliance with GDPR and best security practices. The missing WHOIS data is a significant transparency concern, potentially impacting trustworthiness. Overall, the security posture is adequate for a small non-profit but should be enhanced to meet higher standards and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers to protect against common web vulnerabilities.
  2. Publish clear and accessible privacy policy and terms of service pages to improve compliance and user trust.
  3. Add explicit contact information including emails and phone numbers for general and security-related inquiries.
  4. Investigate and resolve the missing WHOIS data issue to enhance domain transparency and legitimacy.
  5. Enhance accessibility features and SEO optimization to improve user experience and reach.

Technical notes

Notes

The website is built using the Webnode CMS platform, leveraging AWS Cloudfront CDN for content delivery, which supports good performance and scalability. The front-end uses standard HTML5, CSS, and JavaScript, with Google Tag Manager integrated for analytics. The site is mobile responsive and has a clean, professional design. However, there is a lack of advanced frameworks or modern JavaScript libraries detected. Performance is moderate, with no major issues observed. The absence of security headers and limited SEO metadata suggests technical debt in security and optimization areas. The site could benefit from enhanced accessibility compliance and improved metadata for better search engine visibility.
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.
