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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 clinic operates in the healthcare sector with a focus on regenerative medicine, serving a niche market of patients interested in alternative and advanced treatments. Its business model revolves around personalized medical services and supplement sales, supported by a strong online presence and multilingual support. The company leverages patient testimonials and detailed service descriptions to build credibility. Partnerships with supplement providers and use of retargeting advertising indicate a strategic approach to customer engagement and revenue diversification. The domain age and registration data support the legitimacy and stability of the business.

Security posture

The website demonstrates a moderate to good security posture with enforced HTTPS, GDPR-compliant cookie consent, and no visible exposure of sensitive data. However, the absence of explicit security headers like Content-Security-Policy and lack of a security.txt file for vulnerability disclosure are gaps that could be addressed to enhance security maturity. No incident response contacts or security policies are published, which limits transparency in case of security events. The use of third-party scripts and advertising networks introduces some risk that should be regularly audited.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Enhance accessibility features to improve compliance and user experience for all visitors.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Consider publishing a formal security policy and incident response plan to increase transparency and trust.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including JavaScript libraries, Google Analytics, and GDPR compliance plugins. It uses Smart Slider 3 for visual content and Font Awesome for icons. Hosting is managed via REG-INTERNET-CZ with DNS servers ns.vas-hosting.com and ns.vas-hosting.eu. Performance is moderate with good mobile optimization and SEO practices. Some inline styles and multiple minified CSS/JS files indicate optimization efforts. However, accessibility is basic and could be improved. The site uses multiple external domains for analytics, social media, and advertising, which should be monitored for privacy and security compliance.
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.
