As part of the Marsh McLennan group, it holds a strong market position serving corporate clients across multiple industries including finance, healthcare, energy, and government. The website reflects a mature enterprise with comprehensive service offerings and a clear focus on delivering impactful client solutions. Technically, the website leverages Adobe Experience Manager CMS and integrates modern JavaScript libraries and frameworks such as jQuery, Lodash, and Axios. It employs Adobe Helix RUM for performance monitoring and Osano for cookie consent management, indicating a commitment to user experience and privacy compliance. The site is mobile-optimized, accessible, and SEO-friendly, with a moderate performance profile. From a security perspective, the site enforces HTTPS and includes a Content-Security-Policy header, though additional security headers could enhance protection.

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

  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.

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Oliver Wyman operates in multiple sectors including financial services, energy, transportation, healthcare, and technology. Its business model focuses on delivering specialized consulting services with deep industry expertise. The firm benefits from its affiliation with Marsh McLennan, enhancing its market reach and credibility. The website's multilingual and regional subdomains indicate a global footprint. Key competitive advantages include a broad service offering, strong brand recognition, and commitment to sustainability (e.g., CarbonNeutral® certification). The company targets C-suite executives and organizations undergoing transformation, leveraging insights and digital tools to drive impact.

Security posture

The website exhibits a mature security posture with enforced HTTPS, Content-Security-Policy headers, and integration of a consent management platform (Osano) for GDPR compliance. No exposed sensitive data or vulnerable libraries were detected. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not publicly available, representing areas for improvement. The absence of a security.txt file or dedicated security contact reduces transparency in incident handling. Overall, the security measures align with industry best practices for a corporate website, supporting data protection and user privacy.

Recommendations

  1. Enhance Content-Security-Policy with additional directives such as script-src and frame-ancestors to further reduce attack surface.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide explicit contact information for security incidents (e.g., security@ or abuse@ email addresses).
  5. Regularly review and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, indicating a robust enterprise content management platform. It uses modern JavaScript libraries such as jQuery, Lodash, Axios, and UI components like Masonry and Flickity for layout and interactivity. Performance monitoring is handled by Adobe Helix RUM. The site is mobile-optimized with responsive images and accessible design features. Hosting appears to be on AWS infrastructure, inferred from found.io endpoints. The technical implementation is modern and well-structured, supporting a high-quality user experience. Some technical debt may exist in the form of legacy jQuery usage, but overall the stack is appropriate for the business scale. Opportunities exist to improve security headers and streamline third-party script usage to reduce potential risks.
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.
