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. 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

  2. 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"

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

MSD Brasil operates within the healthcare sector as an essential entity under the global Merck umbrella. The business model centers on pharmaceutical innovation, vaccine development, and clinical research, supported by a robust digital presence. The company leverages partnerships and subsidiaries to extend its reach in Brazil and Latin America. The website's content and structure indicate a mature organization with clear branding, compliance with privacy regulations, and a focus on corporate social responsibility. Growth indicators include active recruitment and engagement in clinical studies, while the partnership ecosystem includes recognized health programs and animal health divisions.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, modern security headers, and cookie consent mechanisms aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, explicit security policies and incident response contacts are not publicly available, and no vulnerability disclosure program or security.txt file was found. The use of third-party scripts like Google Tag Manager and Cosmobots SDK is managed with consent banners and external link warnings, reducing risk exposure. Overall, the security maturity is good but could be enhanced by publishing formal security policies and incident response information.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and frameworks.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Disclose data protection officer contact information to enhance GDPR compliance transparency.
  5. Regularly review and audit third-party scripts and external links to mitigate supply chain risks.

Technical notes

Notes

The website is built on WordPress VIP, utilizing Yoast SEO for optimization and Google Tag Manager for analytics. Hosting is via Amazon AWS, indicated by DNS servers. The site employs modern web standards with responsive design, accessibility features, and structured data (JSON-LD) for enhanced SEO. Performance is moderate with lazy loading images and deferred scripts. Cookie consent is managed by OneTrust, ensuring compliance with privacy laws. The technical stack is robust and well-maintained, though continuous monitoring of third-party dependencies is advised to prevent vulnerabilities.
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.
