Security score

58/100

Risk levelMedium

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

The website represents The Merck Access Program for KEYTRUDA®, a pharmaceutical support initiative by Merck & Co., Inc. It targets US healthcare providers, offering enrollment, affordability, coding, and patient assistance resources. The site is professionally designed with consistent branding and clear navigation, supporting its role as a trusted resource for healthcare professionals. Technically, the site uses modern frameworks like Bootstrap and integrates Google Tag Manager and OneTrust for analytics and privacy compliance. Security posture is good with HTTPS and cookie consent mechanisms, though security headers and incident response contacts are absent. The lack of WHOIS registration data for the domain is a notable concern, potentially indicating a staging or proxy domain, which impacts trust. Overall, the site is functional and professional but requires verification of domain legitimacy and enhanced security practices.

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

4 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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

  3. 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

  4. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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 & Co., Inc. is a leading pharmaceutical company with a strong market position in oncology through KEYTRUDA. This site supports their business model by facilitating patient access and reimbursement assistance, targeting healthcare providers. The partnership with McKesson for document upload and accessibility services indicates a robust ecosystem. The business model focuses on patient support programs to improve treatment adherence and market penetration. The site’s content and structure reflect a mature digital presence aligned with enterprise standards, though domain registration inconsistencies warrant further investigation.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and a compliant cookie consent mechanism. However, the absence of key security headers such as Content-Security-Policy and lack of published incident response or vulnerability disclosure information are gaps. No exposed sensitive data or vulnerable libraries were detected. The missing WHOIS data raises questions about domain legitimacy, which is a critical security and trust factor. Overall, the site is secure for users but could improve transparency and technical security controls.

Recommendations

  1. Verify and register the domain properly to align WHOIS data with website content and ownership.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a security.txt file or vulnerability disclosure policy to improve transparency and incident response readiness.
  4. Enhance accessibility features to meet higher standards and improve user experience for all users.
  5. Maintain and regularly audit privacy compliance mechanisms and update data retention policies.

Technical notes

Notes

The website uses a modern tech stack including Bootstrap for responsive design, jQuery for scripting, Font Awesome for icons, and Google Tag Manager for analytics. OneTrust is used for cookie consent management, indicating compliance with privacy regulations. The site is mobile optimized and loads with moderate performance. No CMS or hosting provider details were detected. The HTML is valid and well-structured, though security headers are missing. The site integrates external trusted domains for resources and document upload. Overall, the technical infrastructure supports a professional healthcare service portal but could benefit from enhanced security and performance optimizations.
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.
