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

Stockholms universitet is a major Swedish public university offering a wide range of educational programs and conducting high-quality research. The website reflects a well-established institution with a strong market position in the education sector, targeting students, researchers, and the general public. Key services include education, research dissemination, open lectures, and library services. The site is professionally designed with consistent branding and comprehensive content tailored to its audience. Technically, the website employs modern web technologies such as jQuery, Bootstrap, Matomo analytics, and video embedding platforms, indicating a mature digital infrastructure. Accessibility and SEO optimizations are well implemented, contributing to a positive user experience across devices. From a security perspective, the site enforces HTTPS, respects privacy preferences, and uses cookie consent mechanisms. While security headers are not explicitly detected in the HTML, no critical vulnerabilities or exposed sensitive data were found. The absence of a public security policy or incident response page suggests room for improvement in transparency. Overall, the website demonstrates a high level of professionalism, trustworthiness, and compliance with privacy regulations, making it a reliable digital presence for the university.

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

4 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

Stockholms universitet holds a strong position in the Swedish higher education market, offering diverse academic programs and active research initiatives. The business model is public education and research funding, with a focus on societal impact and lifelong learning. The university maintains partnerships and collaborations, as evidenced by linked domains and thematic content. Growth indicators include recent news on research grants and innovation activities. The website supports engagement with students and staff through dedicated portals and digital tools, reflecting a comprehensive ecosystem.

Security posture

The website exhibits a good security posture with enforced HTTPS and cookie consent management respecting GDPR. Use of Matomo analytics with opt-in consent and Do Not Track handling indicates privacy-conscious practices. However, the lack of visible security headers and absence of a vulnerability disclosure or security policy page are gaps. No signs of malware, phishing, or exposed credentials were detected. Incident response readiness and security culture indicators are not publicly documented, suggesting potential areas for enhancement.

Recommendations

  1. Implement and publish security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Create and make accessible a formal security policy and incident response page to improve transparency and preparedness.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable versions are in use.
  5. Enhance user awareness and trust by highlighting certifications or compliance badges related to security and privacy.

Technical notes

Notes

The website is built on a CMS platform likely Polopoly, using Bootstrap 4 and jQuery 3.3.1 for responsive design and interactivity. Video content is delivered via Screen9 and Kaltura, with YouTube integration managed through consent mechanisms. Analytics are handled by Matomo Tag Manager and Silktide, with Cludo providing search functionality. The site demonstrates good mobile optimization and accessibility features such as ARIA labels and skip links. Performance is moderate, with potential improvements in loading speed by optimizing third-party scripts and assets. The technical stack is modern but could benefit from updated libraries and enhanced security configurations.
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.
