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

UMC Utrecht is a prominent academic medical center in the Netherlands, providing healthcare services and employment opportunities across patient care, research, education, and support functions. The website serves as a recruitment and informational platform targeting healthcare professionals, students, and researchers interested in joining UMC Utrecht or its Wilhelmina Kinderziekenhuis division. The site features comprehensive job listings, educational resources, and employee stories to engage its audience. Technically, the website employs a modern technology stack including Elm for interactive components, multiple analytics platforms such as Google Analytics, Matomo, Hotjar, and tracking pixels from Facebook and LinkedIn. It uses HTTPS with strong SSL configuration and implements a detailed cookie consent mechanism compliant with GDPR requirements. The site is well-optimized for mobile devices and accessibility, with good SEO practices. From a security perspective, the site demonstrates good practices including secure login portals, no visible sensitive data exposure, and cookie consent management. However, it lacks publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms, which are recommended for enhanced transparency and trust. Overall, the website is professional, trustworthy, and well-maintained, with a strong alignment between domain registration data and business claims. The risk profile is low, but improvements in security policy transparency and incident response readiness would further strengthen its posture.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. 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 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

UMC Utrecht holds a strong market position as a leading academic medical center in the Netherlands, focusing on healthcare delivery, research, and education. Its recruitment website reflects a comprehensive business model targeting a wide range of healthcare professionals and support staff. The platform supports growth by offering training, internships, and flexible employment options. The company leverages a multi-channel marketing and analytics ecosystem to optimize candidate engagement and brand presence. Strategic partnerships are evident through linked domains and social media channels. The absence of explicit terms of service and security policies suggests areas for operational maturity enhancement.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure login mechanisms, and GDPR-compliant cookie consent. Multiple tracking and analytics tools are used responsibly with user consent. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. However, the lack of published security policies, incident response contacts, and vulnerability disclosure channels represents a compliance gap and potential risk in incident management and transparency. Enhancing HTTP security headers and publishing formal security documentation would improve the security culture and stakeholder trust.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including abuse and security email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance HTTP security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options.
  5. Maintain transparency on data retention policies related to analytics and tracking to improve privacy compliance.

Technical notes

Notes

The website uses a modern and diverse technology stack including Elm for frontend components and multiple analytics and marketing tools such as Google Analytics, Matomo, Hotjar, Facebook Pixel, and LinkedIn Insight Tag. The site is served over HTTPS with strong SSL configuration, ensuring secure data transmission. Performance is moderate with good mobile optimization and accessibility features. The site lacks a detected CMS, suggesting a custom or proprietary platform. There is no explicit hosting provider identified from the HTML content. The technical implementation supports a professional user experience but could benefit from enhanced security headers and formalized technical documentation.
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.
