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

The website www.keytrudabillingcodes.com serves as a specialized resource for healthcare professionals in the United States, providing coding and billing information related to KEYTRUDA® (pembrolizumab) Injection 100 mg. It is branded by Merck & Co., Inc., a leading pharmaceutical company, and offers access to prescribing information, medication guides, and related programs. The site targets healthcare providers involved in oncology treatment billing and coding, positioning itself as a professional and authoritative source within this niche. Technically, the website is built using modern web technologies including Next.js and React, with integration of Google Tag Manager and OneTrust for cookie consent management. The site demonstrates good mobile optimization, accessibility, and SEO practices, contributing to a positive user experience. Security-wise, the site uses HTTPS and implements cookie consent mechanisms, but lacks visible security headers and explicit security policies or incident response contacts. The absence of WHOIS registration data for the domain is a notable concern, as it conflicts with the professional branding and active content presence, reducing overall trustworthiness. Privacy compliance is well addressed with clear privacy and cookie policies aligned with GDPR standards. Overall, the website is functional, professional, and compliant in privacy aspects but would benefit from enhanced transparency in domain registration and security disclosures.

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. 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 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 & Co., Inc. leverages this website as part of its healthcare professional engagement strategy, focusing on billing and coding support for its oncology product KEYTRUDA. The business model centers on providing accurate, up-to-date information to facilitate proper reimbursement and access to the drug. The site links to related Merck domains and programs, indicating a well-integrated partnership ecosystem. The target customers are healthcare providers in the US, reflecting a focused market segment. The website content and structure suggest a mature digital presence with moderate performance and good technical infrastructure. However, the lack of explicit contact information and missing WHOIS data may indicate gaps in transparency or domain management practices. The site does not appear to monetize directly but supports Merck's broader pharmaceutical business by aiding healthcare professionals in navigating complex billing processes.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and a cookie consent mechanism compliant with privacy regulations. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces its defense-in-depth capabilities. No forms or input fields are present on the homepage, minimizing attack surface, but also limiting user interaction. There is no published security policy or incident response contact information, which are best practices for transparency and readiness. The missing WHOIS registration data raises concerns about domain legitimacy and ownership verification, which is critical for trust in healthcare-related sites. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is moderate but could be significantly improved by adding security headers, publishing security policies, and clarifying domain registration details.

Recommendations

  1. Verify and publish accurate WHOIS domain registration information to improve trust and legitimacy.
  2. Implement and configure essential security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and provide incident response contact information on the website.
  4. Enhance transparency by providing verified contact information such as support emails or phone numbers.
  5. Regularly audit and update privacy and cookie consent mechanisms to maintain compliance with evolving regulations.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering capabilities, supporting good SEO and performance. It uses Webpack for bundling and integrates Google Tag Manager for analytics and tracking. Cookie consent is managed via OneTrust, indicating compliance with privacy laws. The site is mobile responsive and accessible, with well-structured CSS and HTML. However, no CMS or hosting provider details are evident from the content. Performance is moderate, with asynchronous loading of scripts and preloading of key assets. There is no evidence of technical debt or deprecated libraries. Opportunities exist to improve security headers and domain registration transparency to reduce technical risks impacting business operations.
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.
