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.

Dark web exposure

Add-on

Leaked records that mention viatris.co.uk, from OffSeq Breach.

No leaked records found

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 with a focus on pharmaceutical manufacturing and distribution. The company targets healthcare professionals, patients, investors, and potential employees. Its business model leverages global infrastructure to provide access to medicines and services, supported by corporate social responsibility and transparency initiatives. The UK presence is significant with approximately 500 employees and a portfolio treating millions annually. The company maintains a strong partnership ecosystem and a clear digital presence across multiple country-specific domains. Growth indicators include extensive product offerings and active investor relations. The website content and linked domains reinforce Viatris' position as a major player in the pharmaceutical industry.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Privacy and cookie policies are comprehensive and GDPR compliant, with consent mechanisms in place. However, the absence of a dedicated security policy, incident response contact information, and vulnerability disclosure reduces transparency in security governance. No security headers were explicitly detected in the HTML content, suggesting potential for enhancement. The use of multiple third-party scripts and analytics tools is managed with consent but requires ongoing monitoring to mitigate privacy risks. Overall, the security posture is good but could be strengthened by publishing explicit security policies and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance HTTP security headers including Content-Security-Policy and Strict-Transport-Security.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize risk.

Technical notes

Notes

The website is built on a modern technology stack including jQuery, Backbone.js, and Sitecore CMS, indicating a robust and scalable infrastructure. Performance is moderate with good mobile optimization and accessibility features, supporting a positive user experience. SEO is well addressed with proper meta tags and Open Graph data. The site uses Google Tag Manager for analytics and tracking, integrated with cookie consent mechanisms. There is no indication of legacy or vulnerable libraries. Technical risks are low but could be further mitigated by implementing advanced security headers and continuous performance monitoring. The infrastructure supports the company's global healthcare mission effectively.
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.
