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

    • 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

Cornell University operates as an essential entity in the education sector, serving a diverse audience including prospective and current students, researchers, and the public. Its business model centers on delivering education and research services, supported by a broad ecosystem of academic departments, research centers, and public engagement initiatives. The university leverages partnerships and maintains a strong digital presence with multiple subdomains and affiliated sites. The website's comprehensive content and navigation support recruitment, information dissemination, and community engagement. The institution's market position as an Ivy League university provides competitive advantages in attracting top talent and funding. Growth indicators include active research publications and public engagement campaigns. The digital infrastructure supports these goals with integrated analytics and multimedia content delivery.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, use of Google Tag Manager for controlled script deployment, and no exposed sensitive information in the HTML content. However, the absence of several recommended security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options suggests room for improvement. No vulnerability disclosure or incident response information is published, which could hinder coordinated security incident management. The site does not expose vulnerable libraries or insecure forms visibly. Overall, the security practices align with institutional standards but could benefit from enhanced header policies and published security contacts to improve transparency and resilience.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to mitigate common web vulnerabilities.
  2. Publish a formal security policy and incident response contact information to facilitate vulnerability reporting and incident management.
  3. Add a security.txt file at the root domain to standardize vulnerability disclosure processes.
  4. Regularly audit third-party scripts and libraries for security vulnerabilities and update them promptly.
  5. Enhance form security by implementing anti-CSRF tokens and robust input validation to prevent injection attacks.

Technical notes

Notes

The website is built on a modern technology stack utilizing HTML5, CSS3, JavaScript, and jQuery, with integration of Google Tag Manager and Google Analytics for tracking and performance monitoring. Typekit fonts and Kaltura video players enhance the multimedia experience. The site demonstrates good mobile optimization and accessibility features, including ARIA labels and responsive design. Performance is moderate, with asynchronous loading of scripts and lazy loading of images and videos to optimize load times. The absence of a detected CMS suggests a custom or proprietary content management solution. Hosting provider details are not explicitly available. Overall, the technical infrastructure supports a high-quality user experience with opportunities for further optimization and security hardening.
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.
