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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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 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

The university operates in the education sector, serving a large audience including students, academic staff, and international collaborators. It leverages partnerships with regional and international institutions, as evidenced by linked domains and alliance memberships. The business model focuses on public education, research, and community engagement. The presence of multiple certifications and awards enhances its market position and credibility. The website supports recruitment, student services, and knowledge transfer, indicating a mature operational ecosystem. Growth indicators include active event calendars and international cooperation initiatives.

Security posture

The website exhibits a mature security posture with HTTPS enabled and no exposed sensitive data. The use of spam-proof email protection and nofollow attributes on sensitive links indicates attention to security hygiene. However, the absence of explicit security policies, incident response contacts, and security.txt files suggests room for improvement in transparency and vulnerability management. No vulnerable libraries or scripts were detected in the provided content. Security headers are not explicitly visible and should be implemented to enhance protection against common web threats.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and provide clear incident response contact channels.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance visibility of contact information including phone numbers and physical addresses to improve user trust.

Technical notes

Notes

The website employs a stable and modern technology stack including jQuery 3.5 and Bootstrap for responsive design. The HTML structure is valid and supports accessibility features such as ARIA labels and skip links. Performance is moderate with no heavy external dependencies detected. SEO is supported by proper meta tags and multilingual alternate links. The site lacks a detected CMS, suggesting a custom or university-managed platform. Hosting details are not explicit but DNS servers indicate academic network infrastructure. Opportunities exist to improve technical security configurations and analytics integration for better user insights.
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.
