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

Duke Corporate Education (Duke CE) is a globally recognized leadership development organization affiliated with Duke University and its Fuqua School of Business. With over 25 years of experience, Duke CE offers customized leadership programs, advisory services, and ready-to-learn offerings designed to empower business leaders and organizations to navigate disruption and drive transformation. Their market position is strong, supported by a global footprint across more than 85 countries and a robust network of educators and clients. The company emphasizes sustainability and ESG leadership, reflecting contemporary business priorities. Technically, the website is built on a modern WordPress CMS platform, leveraging popular libraries such as jQuery, Bootstrap, and Slick Carousel, alongside HubSpot marketing and analytics tools. The site demonstrates good performance, mobile optimization, and SEO practices, providing an excellent user experience with clear navigation and professional design. From a security perspective, the site enforces HTTPS and uses several third-party analytics and marketing scripts responsibly. However, some security headers are not explicitly detected and could be improved. No critical vulnerabilities or exposed sensitive data were found. The WHOIS data is notably absent or private, which introduces some uncertainty regarding domain registration transparency, but the strong brand affiliation and professional content mitigate this risk. Overall, Duke CE presents a credible, professional, and secure online presence suitable for its educational and corporate audience. Strategic recommendations include enhancing security headers, verifying domain registration details, and formalizing incident response contact information to further strengthen trust and compliance.

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

6 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

  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

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

Duke CE operates in the education sector, specializing in corporate leadership development. Their business model focuses on delivering tailored programs and advisory services to large enterprises globally. The company leverages its affiliation with Duke University to enhance credibility and market positioning. Revenue streams likely include custom program fees, subscription-based platforms, and certificate offerings such as the ESG Leadership Academy. The target customers are business leaders and organizations seeking leadership transformation. Growth indicators include a broad geographic presence and a large network of educators and engaged leaders. The partnership ecosystem includes Duke University and Fuqua School of Business, enhancing thought leadership and content quality. The company maintains a strong digital presence with integrated marketing and analytics tools supporting customer engagement and lead generation.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and use of reputable third-party analytics and marketing services. Security best practices such as asynchronous script loading and no visible sensitive data exposure are observed. However, the absence of explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No incident response or security policy pages were found, indicating a potential gap in transparency and readiness. The lack of WHOIS data reduces domain registration trustworthiness, which should be addressed. Overall, the site is secure for typical business use but would benefit from enhanced header policies and published security governance documentation.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  3. Verify and update WHOIS domain registration details to enhance trust and compliance with domain ownership transparency.
  4. Regularly audit third-party scripts and marketing tools for security vulnerabilities and privacy compliance.
  5. Continue to maintain and improve mobile optimization and accessibility to ensure inclusive user experience.

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.
