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

The Česká nefrologická společnost (Czech Society of Nephrology) is a non-profit professional organization dedicated to nephrology, encompassing medical professionals and researchers focused on kidney diseases. The website serves as an information hub for both professionals and patients, providing news, event calendars, and partner collaborations. The organization holds a reputable position within the Czech healthcare sector, supported by partnerships with recognized international nephrology bodies. Technically, the website employs modern analytics tools such as Google Analytics and Fathom, integrates Google Maps API, and demonstrates good mobile responsiveness and accessibility features. However, it lacks visible privacy and cookie policies, which are critical for GDPR compliance and user trust. Security posture is generally good with HTTPS enforced, but the absence of security headers and vulnerability disclosures suggests room for improvement. WHOIS data is unavailable, likely due to privacy protection, but the website's professional presentation and partner affiliations support its legitimacy. Overall, the site is well-maintained and trustworthy but should enhance privacy compliance and security transparency.

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

9 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

    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 Content-Security-Policy 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
  • 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 small-sized non-profit entity within the healthcare sector, specifically nephrology. Its business model revolves around professional association services, including information dissemination, education, and community building. The website's content and partner network indicate strong positioning in the Czech nephrology community with international ties. Revenue streams are likely membership fees, grants, and sponsorships, though not explicitly stated. The target audience includes medical professionals, researchers, and patients seeking nephrology-related information. The partnership ecosystem includes prominent nephrology organizations, enhancing credibility and outreach. Growth indicators include regular event updates and active news postings. Strategic observations suggest the organization could benefit from improved digital privacy and security practices to align with evolving regulatory requirements.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible exposure of sensitive data. The use of secure forms and absence of vulnerable libraries are positive indicators. However, the lack of security headers such as Content-Security-Policy and absence of a published vulnerability disclosure or security.txt file indicate gaps in security best practices. No incident response or security contact information is provided, which could hinder timely reporting and mitigation of security issues. Compliance with GDPR is uncertain due to missing privacy and cookie policies. Overall, the security posture is adequate for a non-commercial informational site but requires enhancements to meet higher standards and regulatory expectations.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms to ensure GDPR compliance.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information for security incidents and consider publishing a vulnerability disclosure or security.txt file.
  4. Improve transparency of domain registration data or provide justification for privacy protection to enhance trust.
  5. Regularly review and update third-party scripts and analytics tools to minimize security risks and ensure data privacy.

  6. No contact emails or phone numbers explicitly provided on homepage
  7. Good mobile and accessibility features observed
  8. No security.txt or vulnerability disclosure found
Technical notes

Notes

The website uses a combination of Google Analytics, Fathom Analytics, and Google Tag Manager for tracking and analytics, indicating a mature approach to user data collection and analysis. The integration of Google Maps API enhances user experience with location-based services. The site is mobile responsive and includes accessibility features such as skip navigation links and ARIA roles. The HTML structure is modern and includes meta viewport tags for responsiveness. However, no CMS or hosting provider information is evident, and WHOIS data is missing, which could indicate privacy protection or domain registration issues. Performance is moderate with asynchronous loading of scripts. Technical debt appears low, but the absence of security headers and privacy policies suggests areas for modernization and compliance improvements.
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.
