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

Breach holds no records for viatris.co.uk right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Viatris holds a strong market position as a leading pharmaceutical company with a large UK presence and a global footprint. Their business model centers on pharmaceutical manufacturing, distribution, and healthcare partnerships, supported by corporate social responsibility initiatives. The company maintains a broad portfolio of products across therapeutic areas and invests in sustainable operations. The website links to multiple country-specific domains, reflecting a global partnership ecosystem. Growth indicators include a large employee base in the UK and extensive product reach. The company leverages digital channels for investor relations and corporate communications, enhancing transparency and stakeholder engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and no exposed sensitive data. Use of secure external linking practices and modern libraries reduces risk. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts represent areas for improvement. No vulnerability disclosure program or security.txt file is present, limiting transparency for security researchers. Overall, the security maturity is good but could be enhanced by formalizing security governance and incident response communications.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a dedicated security policy page and provide incident response contact information to improve transparency and readiness.
  3. Establish a vulnerability disclosure program and host a security.txt file to facilitate responsible reporting.
  4. Enhance form security by integrating anti-CSRF tokens and CAPTCHA mechanisms where user input is collected.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Notes

The website uses a modern technology stack with jQuery 3.5.1, JW Player for media, and Google Tag Manager for analytics and marketing. The HTML structure is valid and supports responsive design with good mobile optimization and accessibility features. SEO is supported by proper meta tags, Open Graph tags, and canonical links. Performance is moderate, with potential improvements possible through optimization of media assets and script loading. No CMS or hosting provider details are explicitly detected. The site architecture supports multi-country localization with links to numerous country-specific domains, indicating a scalable global platform.
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.
