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

The University of California website represents a large, well-established public university system with a strong focus on education, research, healthcare, and public service. The site provides comprehensive information about its campuses, health centers, national labs, and outreach programs, targeting students, faculty, researchers, and the general public. Technically, the site is built on Drupal 10, uses modern web technologies, and integrates Google Analytics and social sharing tools. The website is mobile-optimized, accessible, and professionally designed, offering a high-quality user experience. From a security perspective, the site enforces HTTPS and follows several best practices, though explicit security headers and incident response information are not prominently displayed. Privacy and terms of service policies are present and comprehensive, indicating good compliance posture, though a cookie consent mechanism is missing, which could be improved for GDPR compliance. The WHOIS data for the exact queried domain is missing, which is unusual but likely due to querying the 'www' subdomain rather than the root domain. Overall, the site appears legitimate and trustworthy. The risk assessment is moderate with no critical vulnerabilities detected. Strategic recommendations include enhancing security headers, implementing cookie consent, and publishing security policies and incident response contacts to improve transparency 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

3 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 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

The University of California holds a leading position in public higher education and research in the United States. Its competitive advantages include a large network of campuses, medical centers, national labs, and agricultural extension programs. The business model is public education and research funded by government and tuition, serving a broad audience including students, researchers, and the public. Revenue streams likely include tuition, government grants, research funding, and healthcare services. The partnership ecosystem includes government agencies, research institutions, and community organizations. Growth indicators include ongoing research breakthroughs and expansion of educational programs. The website reflects a mature, enterprise-level organization with consistent branding and strong market presence.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposed sensitive data. The use of Drupal CMS implies built-in security features such as CSRF protection on forms. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a minor gap. No incident response or security contact information is provided, which limits transparency. Privacy policies are comprehensive and GDPR compliant, but cookie consent is missing. Overall, the site is secure but could improve in transparency and explicit security controls.

Recommendations

  1. Implement and explicitly configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to enhance transparency and trust.
  4. Verify and correct WHOIS data for the root domain to ensure domain registration transparency.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built on Drupal 10, a modern and secure CMS platform, with integration of Google Tag Manager for analytics and AddToAny for social sharing. The site uses HTML5 video and responsive CSS for a rich multimedia experience. Performance is moderate, with good mobile optimization and accessibility features. The site structure is clear and SEO optimized with proper meta tags and Open Graph data. No major technical debt or outdated libraries were detected. Hosting provider details are not explicit. Opportunities exist to improve security headers and cookie consent implementation.
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.
