Risk levelLow

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

Hanze Hogeschool Groningen is a well-established higher education institution in the Netherlands, offering a broad portfolio of academic programs, research initiatives, and professional collaborations. The website reflects a mature digital presence with comprehensive content targeting students, professionals, and organizations. Technically, the site employs modern web technologies including Google Tag Manager and image optimization services, with good mobile responsiveness and accessibility. Security posture is solid with HTTPS and CSRF protections, though explicit security headers and formal security policies are not evident. Privacy compliance is partial, lacking visible privacy and cookie policies or consent mechanisms. Overall, the site demonstrates high business credibility and professionalism but could improve transparency on privacy and security disclosures.

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 finding rated critical or high. Fix these first.

  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.

    • 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

The institution holds a strong market position as a regional educational leader with extensive offerings in education, research, and innovation. Its business model focuses on degree education, professional training, and collaborative projects with organizations. The presence of partner domains such as recruitment and student portals indicates a well-integrated ecosystem. The website content and structure support clear navigation and user engagement, targeting a diverse audience including prospective students and professionals. Growth indicators include active news and event sections and internationalization support.

Security posture

The website uses HTTPS with good SSL configuration and implements CSRF tokens for form security. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to enhance protection against common web attacks. No vulnerability disclosure or incident response information is published, which could be improved to foster trust and readiness. Privacy compliance is limited by the absence of visible privacy and cookie policies and consent mechanisms, which are critical under GDPR. No exposed sensitive data or vulnerable libraries were detected in the provided content.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Implement a cookie consent mechanism to obtain user consent for tracking technologies.
  3. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Establish and disclose a vulnerability disclosure program or security.txt file.
  5. Provide clear contact information for data protection officer and incident response.

Technical notes

Notes

The website uses modern JavaScript and asynchronous loading of Google Tag Manager scripts, indicating a focus on performance and analytics. Images are served via a specialized image service with JWT tokens for secure delivery and optimized formats (WebP). The site is mobile responsive with accessibility considerations such as skip links and ARIA attributes. No specific CMS or framework is explicitly detected, suggesting a custom or proprietary platform. Performance is moderate with room for improvement in loading speed and SEO metadata completeness. The site structure supports multilingual content with hreflang tags for Dutch, English, and German.
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.
