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

Bayer is a global enterprise operating in healthcare and agriculture sectors, with a long-standing presence in the Czech Republic since 1884. The website reflects a professional corporate identity with consistent branding and a focus on providing information about Bayer's operations in Czechia. The technical infrastructure is modern, leveraging Drupal 11 CMS, Google Tag Manager, and OneTrust for cookie compliance, indicating a mature digital presence. Security posture is strong with HTTPS enforced and clickjacking protections in place, although explicit security policies and incident response contacts are not published on the site. Privacy compliance is supported by cookie consent mechanisms, but a clearly accessible privacy policy page was not identified in the provided content. WHOIS data for the domain is not publicly available, which is unusual for a major corporation but does not detract significantly from the site's legitimacy given the brand recognition and content quality. Overall, the site is well-designed, secure, and compliant with basic privacy standards, suitable for a large multinational corporation.

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

4 findings rated critical or high. Fix these first.

  1. 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

      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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Bayer's market positioning as a leader in healthcare and agriculture is evident from the website content and branding. The business model focuses on pharmaceuticals, consumer health products, and crop science innovations. The target audience includes healthcare professionals, agricultural stakeholders, and the general public in Czechia. The site supports corporate communications and investor relations, indicating a comprehensive business ecosystem. The lack of explicit contact details and security disclosures suggests an opportunity to enhance transparency and customer engagement. The use of advanced web technologies and compliance tools reflects a commitment to digital maturity and regulatory adherence.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and security headers implied by the use of the Seckit Drupal module. Cookie consent is managed via OneTrust, supporting GDPR compliance. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site would benefit from publishing a security.txt file and clear security incident contact information to improve trust and compliance.

Recommendations

  1. Publish a detailed privacy policy page prominently linked on the site.
  2. Add explicit security and incident response policies accessible to users.
  3. Implement and publish a vulnerability disclosure or security.txt file.
  4. Provide clear company contact emails and phone numbers for support and security incidents.
  5. Regularly audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The site is built on Drupal 11 CMS with modern front-end libraries such as jQuery UI and Font Awesome. It integrates Google Tag Manager and Google Analytics for tracking and performance monitoring, alongside OneTrust for cookie consent management. The site is mobile optimized and accessible, with good SEO practices including meta tags and Open Graph data. Performance is moderate, with some reliance on external CDNs and tracking scripts. The technical stack is robust but could be enhanced by adding explicit hosting provider information and performance optimization details. No critical technical debt or vulnerabilities were identified in the provided content.
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.
