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

Symptomy.cz is a Czech-language health information portal operated by Synetix s.r.o., providing a comprehensive database of symptoms, diseases, anatomical information, diagnoses, vaccinations, and medical specialties. The site targets the general public seeking medical knowledge and health-related guidance. It has been active since 2009 and positions itself as a trusted informational resource with references to official Czech health institutions. Technically, the website employs a moderate technology stack including Bootstrap 3, jQuery 1.11.1, Google Analytics, and Adsense for monetization. The site is mobile-optimized and offers good navigation and content relevance. Security-wise, the site uses HTTPS but lacks several important security headers and cookie consent mechanisms, which are recommended for GDPR compliance. The absence of WHOIS data for the domain is a notable concern, impacting trustworthiness despite the professional content and branding. Overall, the website is functional and informative but would benefit from enhanced security and privacy compliance 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

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 business operates in the healthcare information sector, focusing on symptom and disease education for the Czech market. Its business model relies primarily on advertising revenue through Google Adsense. The portal's competitive advantage lies in its extensive, well-organized medical content and official references, which build credibility. The target audience includes general users interested in health and medical symptoms. Growth indicators include regular content updates and a health magazine section. The partnership with DomaciMed.cz suggests some ecosystem collaboration. The company is small-sized and privately held by Synetix s.r.o., with no subsidiaries or parent companies indicated. The website's professional presentation supports its market position as a reliable health information source.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible sensitive data exposure. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. The use of an outdated jQuery version may expose the site to known vulnerabilities. There is no published security policy, incident response plan, or vulnerability disclosure mechanism, which limits transparency and readiness for security incidents. Cookie consent mechanisms are absent, potentially impacting GDPR compliance. Overall, while basic security practices are in place, there is room for improvement to enhance protection and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a cookie consent banner and mechanism to comply with GDPR and enhance user privacy transparency.
  3. Update JavaScript libraries, especially jQuery, to the latest secure versions to mitigate vulnerabilities.
  4. Publish a clear security policy and incident response contact information to improve trust and readiness.
  5. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.

Key observations

  1. Website is a Czech health information portal focused on symptoms and diseases.
  2. Content is comprehensive and well-structured with multiple health-related categories.
  3. No WHOIS data available, which is unusual and reduces domain trust.
  4. No explicit privacy or cookie consent banners detected, though privacy policy page exists.
  5. Use of Google Adsense and Google Analytics for monetization and tracking.
  6. No direct company contact emails or phone numbers found on main page; contact form available.
  7. No security.txt or incident response information published.
  8. Website uses HTTPS and modern web technologies but uses an outdated jQuery version.
  9. No signs of adult or NSFW content; content is safe for general audiences.
Technical notes

Notes

The website uses a classic web technology stack with Bootstrap 3 and jQuery 1.11.1, which is somewhat outdated but still functional. Google Analytics and Adsense are integrated for analytics and monetization. The site is mobile responsive and has good SEO meta tags and structured navigation. Performance is moderate, with no major issues detected. Accessibility features are basic but present. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not discernible from the HTML content. Technical debt is indicated by the use of older JavaScript libraries, which should be updated to reduce security risks and improve maintainability.
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.
