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

GlaxoSmithKline plc (GSK) is a leading global healthcare company specializing in pharmaceuticals, vaccines, and consumer healthcare products. The Czech Republic location page reflects GSK's strong presence in the region, targeting healthcare professionals, patients, and partners with comprehensive information about their operations. The website is professionally designed, mobile-optimized, and provides clear navigation and contact information, reinforcing GSK's market position as a large multinational enterprise in the healthcare sector. Technically, the site leverages modern JavaScript frameworks such as Nuxt.js and Vue.js, ensuring a responsive and performant user experience. Analytics and marketing tools like Google Analytics and Google Tag Manager are used responsibly with privacy compliance in mind. Security-wise, the website enforces HTTPS, implements key security headers, and shows no signs of vulnerabilities or exposed sensitive data, indicating a mature security posture. However, the absence of WHOIS data for the domain is noted, likely due to registry restrictions rather than malicious intent. Overall, the site demonstrates high professionalism, trustworthiness, and compliance with privacy regulations.

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

2 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.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

Business profile

GSK operates in the healthcare sector with a business model focused on pharmaceutical R&D, vaccine production, and consumer healthcare distribution. The company targets a broad audience including healthcare providers, patients, investors, and partners. GSK's global brand and ISO certifications provide competitive advantages and trust signals. The website content and structure support GSK's enterprise scale and market leadership. The presence of comprehensive privacy and cookie policies, along with GDPR compliance, reflects the company's commitment to regulatory adherence. The use of modern web technologies and analytics tools indicates a digitally mature organization. No suspicious domains or partners were identified, and the company maintains a consistent branding and communication strategy across its digital assets.

Security posture

The website exhibits a strong security posture with HTTPS enforced and multiple security headers such as Strict-Transport-Security, X-Content-Type-Options, and Content-Security-Policy implemented. No vulnerabilities or exposed sensitive information were detected in the HTML content. Forms appear to be secure, likely protected against CSRF and other common web attacks. The absence of a publicly visible vulnerability disclosure policy or incident response contact is a minor gap that could be addressed to enhance transparency and readiness. Overall, the security measures align well with industry best practices for a healthcare enterprise, supporting data protection and user trust.

Recommendations

  1. Publish a clear vulnerability disclosure policy and security contact information to improve transparency and encourage responsible reporting.
  2. Enhance incident response visibility by providing dedicated security or abuse contact channels on the website.
  3. Maintain regular security audits and update security headers to adapt to emerging threats.
  4. Continue to monitor and ensure GDPR and other privacy regulation compliance, especially regarding data retention and user consent.
  5. Consider publishing more detailed information about security certifications and frameworks adopted to strengthen trust.

Technical notes

Notes

The website is built using modern JavaScript frameworks Nuxt.js and Vue.js, providing a responsive and dynamic user experience. The use of Google Analytics and Google Tag Manager supports effective marketing and user behavior analysis while respecting privacy. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, likely due to rich content and scripts, but overall user experience remains smooth. No CMS like WordPress or Drupal was detected, indicating a custom or enterprise-grade solution. Hosting provider details are not explicitly available. The technical stack and implementation reflect a well-maintained digital infrastructure suitable for a global healthcare company.
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.
