Risk levelMedium

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

The website www.keytrudahcp.com serves as a professional resource for healthcare professionals regarding KEYTRUDA® (pembrolizumab), a pharmaceutical product by Merck. It provides detailed information on FDA-approved indications, clinical trial data, safety, dosing, and biomarker testing. The site is clearly targeted at oncology healthcare providers and is branded consistently with Merck's corporate identity. Technically, the site is built using modern frameworks such as React and Gatsby, with extensive use of third-party analytics and marketing tools. The site is mobile-optimized, fast, and accessible, offering a high-quality user experience. Security posture is generally good with HTTPS enforced, but lacks explicit security headers and published security policies. Privacy compliance is limited due to absence of visible privacy and cookie policies. WHOIS data is missing, which raises some concerns about domain registration transparency, but the overall professional presentation and association with Merck mitigate this risk. Strategic recommendations include enhancing privacy disclosures, adding security headers, and publishing incident response contacts to improve trust and compliance.

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

3 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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

Merck positions KEYTRUDA as a leading oncology immunotherapy with a broad range of FDA-approved indications. The website supports healthcare professionals with comprehensive product information, clinical data, and biomarker testing resources. The business model focuses on pharmaceutical product education and support, targeting oncologists and related healthcare providers. The presence of partner domains and extensive marketing analytics indicates a mature digital marketing strategy. The site reflects enterprise-level operations consistent with a global pharmaceutical leader. No direct revenue streams or e-commerce functions are present, emphasizing informational and support roles. The partnership ecosystem includes Merck's corporate site and patient-facing portals, reinforcing brand consistency and market reach.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and no visible exposure of sensitive data. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests room for improvement. No vulnerabilities or malware indicators were detected in the provided content. The site lacks published security policies or incident response contacts, which are important for compliance and trust. The use of multiple third-party scripts introduces potential risk vectors that require ongoing monitoring. Overall, the security maturity is moderate to good but would benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR and privacy compliance.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options, X-XSS-Protection) to strengthen security posture.
  3. Publish a security policy and incident response contact information to enhance trust and preparedness.
  4. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  5. Consider WHOIS privacy transparency or domain registration verification to improve domain legitimacy perception.

Technical notes

Notes

The website is built on a modern React and Gatsby framework, ensuring fast performance and excellent mobile responsiveness. It leverages multiple analytics and marketing tools including Google Tag Manager, Demandbase, Facebook Pixel, LinkedIn Insight Tag, and Bing Ads, indicating a sophisticated digital marketing infrastructure. The site uses structured data (JSON-LD) for SEO and semantic clarity, targeting medical audiences and substance information. No CMS beyond Gatsby was detected, and hosting provider details are not explicit. The site shows good accessibility and SEO optimization but lacks some security headers. Overall, the technical implementation is robust and modern, supporting a professional healthcare information 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.
