Česká asociace sester, z.s. is a professional nursing association based in the Czech Republic, providing membership services, educational programs, events, and advocacy for nursing professionals. The website serves as an information hub for members and the public, offering news, event registrations, and resources. The organization maintains partnerships with reputable healthcare companies and educational institutions, enhancing its credibility and service offerings. Technically, the website employs standard web technologies including jQuery, Google Analytics, Google Tag Manager, and Google reCAPTCHA for security and analytics. The site is accessible, mobile-optimized, and presents content in Czech with some multilingual options. Security posture is generally good with HTTPS enforced and bot protection via reCAPTCHA, but lacks some security headers and explicit privacy and cookie policies. WHOIS data is unavailable, which limits full domain legitimacy verification. Overall, the site is professional and trustworthy for its intended audience but would benefit from enhanced privacy compliance and security disclosures.

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

13 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 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

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

The association holds a strong position within the Czech healthcare sector as a key professional body for nurses. Its business model is non-profit, focusing on member services, education, and advocacy rather than commercial sales. Revenue streams likely include membership fees, event fees, and partnerships. The target audience is nursing professionals and healthcare stakeholders in the Czech Republic. The website reflects a mature organization with consistent branding and a broad partnership ecosystem including medical device companies, publishers, and educational platforms. Growth indicators include active event scheduling and ongoing educational offerings. Strategic observations suggest a focus on professional development and sector influence, with potential to improve digital privacy and security transparency.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms from automated abuse. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No security or incident response policies are published, and no vulnerability disclosure or security.txt files are present, which limits transparency and preparedness for security incidents. The lack of WHOIS data is a concern for domain legitimacy verification. Overall, the site is secure enough for general informational use but should enhance security headers and publish security policies to improve trust and compliance.

Recommendations

  1. Publish clear and comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Publish a security policy and incident response contact information to enhance transparency and preparedness.
  4. Investigate and resolve the missing WHOIS data issue to improve domain legitimacy and trust.
  5. Regularly audit third-party scripts and tracking tools to ensure minimal privacy impact and compliance.

Technical notes

Notes

The website uses a traditional web stack with jQuery 3.2.1 and integrates Google Analytics and Tag Manager for analytics, along with Google reCAPTCHA v3 for bot protection. The site is served over HTTPS with good SSL configuration. The HTML content is well-structured with meta tags for SEO and Open Graph tags for social sharing. The site is mobile responsive and has clear navigation menus. Performance is moderate, with some external dependencies on third-party scripts. No CMS or hosting provider information is explicitly detected. Accessibility is basic but functional. There is room for improvement in SEO and accessibility features. Overall, the technical implementation supports the business needs but could be modernized with newer frameworks and enhanced security practices.
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.
