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

The website represents Sjednocená organizace nevidomých a slabozrakých České republiky, a large non-profit organization dedicated to supporting blind and visually impaired individuals across the Czech Republic. The organization provides a wide range of social services including counseling, training, guide dog programs, and barrier removal, positioning itself as a leading national entity in this sector. The website content is comprehensive, well-structured, and targets both members and the general public interested in their services. Technically, the site uses a modern JavaScript stack with jQuery, Bootstrap, and Masonry for layout, hosted by T-Mobile Czech Republic, and integrates Google Analytics for visitor tracking. Privacy compliance is addressed with GDPR-related pages and cookie consent mechanisms. Security posture is moderate with HTTPS usage and no exposed sensitive data, but lacks advanced security headers and vulnerability disclosure policies. The absence of WHOIS data reduces domain trustworthiness, but the website's content and external references support its legitimacy. Overall, the site is professional, accessible, and trustworthy with room for security and technical improvements.

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

11 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

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 · found on this site
  • 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

SONS operates as a non-profit membership organization with a nationwide presence, serving over 10,000 members through numerous regional branches. Its business model relies on social service provision, advocacy, and fundraising campaigns such as the 'Bílá pastelka' collection. The organization benefits from EU co-funded projects, enhancing its service quality and reach. Its partnership ecosystem includes donation platforms, hosting providers, and web management firms. The website reflects a mature digital presence with clear navigation and multilingual support (Czech and English). Growth indicators include active project implementation and community engagement via social media. Strategic observations highlight the importance of maintaining trust through transparency, improving security posture, and expanding digital accessibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent implemented, reflecting GDPR compliance efforts. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates potential areas for enhancement. The site lacks a public vulnerability disclosure policy or security.txt file, which could improve incident response readiness. The use of third-party scripts and analytics is standard but should be regularly audited for vulnerabilities. Overall, the security culture appears cautious but could benefit from formalized policies and technical hardening to mitigate emerging threats and comply with evolving regulations like NIS2.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and incident management.
  3. Regularly update all JavaScript libraries and dependencies to their latest secure versions to reduce risk of exploitation.
  4. Enhance accessibility features to meet WCAG standards, improving usability for visually impaired users.
  5. Increase transparency by providing detailed contact information including phone numbers and physical addresses to strengthen business credibility.

Technical notes

Notes

The website is built on a custom or unknown CMS platform utilizing jQuery 3.6.1 and Bootstrap 3.3.6 for responsive design and UI components. Masonry layout is used for dynamic content arrangement. Google Analytics and Navrcholu.cz scripts provide visitor tracking. Hosting is provided by T-Mobile Czech Republic, indicating a reliable infrastructure. Performance is moderate with room for optimization, especially in image loading and script management. The site is mobile optimized with basic accessibility features but could improve semantic markup and ARIA attributes. SEO is basic with meta tags present but lacks advanced structured data like JSON-LD or Open Graph tags. Technical debt is moderate due to older Bootstrap version and lack of modern security headers. Opportunities exist for modernization and improved compliance with web standards.
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.
