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

5 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

      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';…

  3. 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

Viatris operates in the healthcare sector as a large pharmaceutical entity formed from the merger of Mylan and Upjohn. It focuses on providing access to affordable medicines, leadership in sustainable healthcare solutions, and partnerships to enhance patient care. The company targets healthcare providers, patients, investors, and potential employees, leveraging a global network of country-specific websites. Its business model centers on pharmaceutical manufacturing, distribution, and corporate social responsibility. The presence of investor relations and compliance lines indicates a mature governance structure. The company’s extensive product portfolio and significant market share in the Netherlands position it as a key player in the pharmaceutical industry.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a cookie consent mechanism compliant with GDPR. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. There is no publicly available security policy or incident response information, which could enhance transparency and trust. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of a vulnerability disclosure policy or security.txt file suggests an opportunity to improve security communication with external researchers. Overall, the security posture is good but can be strengthened with additional best practices and transparency.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance contact information availability by providing verified company emails and phone numbers for customer and security contacts.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerable versions are in use and maintain up-to-date dependencies.

Technical notes

Notes

The website is built on the Sitecore CMS platform, utilizing a modern JavaScript stack including jQuery and JWPlayer for media content. Google Tag Manager is used for analytics and marketing tags, with asynchronous loading to optimize performance. The site is mobile-optimized with responsive design and accessibility features such as skip links and font resizing controls. Performance is moderate, with potential improvements by optimizing script loading and reducing dependencies. The site structure and metadata are well-implemented, supporting SEO and social sharing. No hosting provider details were explicitly detected. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
