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

Labcorp is a globally recognized life sciences and healthcare company specializing in laboratory diagnostics and drug development services. The company serves a broad audience including patients, healthcare providers, organizations, and biopharma companies, positioning itself as a leader in guiding vital healthcare decisions. The website reflects a mature digital presence with comprehensive content, clear navigation, and professional branding consistent with its enterprise status. The inclusion of subsidiaries such as Invitae highlights its expansive market reach and diversified service offerings. Technically, the website leverages Adobe Experience Manager as its CMS, integrates Adobe Launch for tag management, and employs OneTrust for consent management, indicating a modern and compliant infrastructure. The site is mobile-optimized, accessible, and SEO-friendly, supporting a positive user experience. Security posture is strong with HTTPS enforced and standard security headers implied, though explicit security policies and incident response details are not publicly disclosed. Overall, the website demonstrates a high level of professionalism, trustworthiness, and compliance with privacy regulations such as GDPR. The absence of WHOIS data is noted but likely due to privacy protection measures rather than suspicious activity. Strategic recommendations include enhancing transparency around security policies and incident response, and publishing vulnerability disclosure information to further strengthen trust and security culture.

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. 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

Labcorp operates in the healthcare sector with a focus on diagnostics and life sciences. Its business model centers on providing laboratory testing services, drug development support, and real-world data solutions to a diverse client base including individuals, healthcare providers, and biopharma companies. The company holds a strong market position as a global leader, supported by its enterprise scale and subsidiary network. Revenue streams likely include lab testing fees, biopharma partnerships, and data services. The website's integration with career and investor portals indicates organizational maturity and growth orientation. Partnerships and subsidiaries such as Invitae expand its capabilities in genetic testing and diagnostics, enhancing competitive advantage. The company maintains a robust digital ecosystem with compliance and privacy as key operational pillars.

Security posture

The website exhibits a solid security posture with HTTPS enforced and use of security headers, contributing to data confidentiality and integrity. The presence of a consent management platform aligns with privacy compliance requirements. However, the lack of explicit security policy documentation and incident response contact information represents a gap in transparency and readiness communication. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable third-party libraries and modern CMS reduces risk exposure. To improve, Labcorp should consider publishing detailed security policies, incident response procedures, and a vulnerability disclosure program to enhance stakeholder confidence and regulatory compliance.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and standards.
  2. Establish and publicize an incident response contact channel for security issues.
  3. Implement and disclose a vulnerability disclosure or bug bounty program.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency on certifications and compliance frameworks to build trust.

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.
