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

The website biochemicka.cz represents RNDr. Michaela Bebová, a nutrition and biochemistry expert with over 15 years of experience. The business offers personalized consulting, seminars, product reviews, corporate nutrition consulting, publishing, and media appearances. The site targets individuals and companies interested in nutrition and healthy lifestyle, leveraging media partnerships to enhance credibility. Technically, the website uses modern frontend technologies including Bootstrap and Google Fonts, with tracking via Google Analytics and Tag Manager. The site is mobile responsive and well-structured, though accessibility and SEO could be improved. Security posture is moderate with HTTPS in use but lacks visible security headers and explicit privacy or cookie policies, indicating compliance gaps. The absence of WHOIS data reduces domain trustworthiness, but the professional content and contact information support legitimacy. Overall, the site is functional and professional but would benefit from enhanced security and privacy compliance.

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

10 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

      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

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 sector focusing on nutrition and healthy lifestyle consulting. It maintains a small but professional presence with strong media collaborations and editorial roles that enhance market positioning. Revenue streams likely include consulting fees, seminar hosting, product reviews, and publishing. The partnership ecosystem includes notable Czech media and health-related platforms, supporting brand visibility. The business model is service-oriented with a personal brand focus. Growth indicators include ongoing media presence and diversified service offerings. Strategic observations suggest opportunities to formalize privacy and security policies to align with regulatory requirements and improve trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and secure form submission. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options weakens defense against common web attacks. No vulnerabilities or exposed sensitive data were detected in the content. Compliance with GDPR is questionable due to missing privacy and cookie policies. Incident response and security policy information are absent, indicating limited formal security governance. The site would benefit from implementing security best practices and formalizing data protection measures to reduce risk and enhance user trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options.
  3. Conduct regular security audits of third-party scripts and libraries.
  4. Establish an incident response plan and publish security contact information.
  5. Enhance accessibility and SEO features to improve user experience and visibility.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap and Google Fonts, ensuring responsive design and good user experience on mobile devices. Google Analytics and Tag Manager are integrated for user behavior tracking. Performance is moderate with no major issues detected. The site lacks a detected CMS, suggesting a custom or static site build. Technical debt appears low but could be improved by adding accessibility features and optimizing SEO metadata. Hosting provider details are not available. Overall, the technical infrastructure supports the business needs but can be enhanced for security and 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.
