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

7 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 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';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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 website holds a dominant position in the Norwegian educational and research dissemination market, leveraging partnerships with leading universities and cultural institutions. Its non-profit business model focuses on providing free, high-quality educational content. The absence of direct commercial advertising and the presence of institutional backing enhance its credibility. The site ecosystem includes related encyclopedia projects under the same brand, expanding its reach. The target audience is broad, including students, researchers, and the general public seeking reliable information. Growth is supported by continuous content updates and strong academic collaboration.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, secure form handling with CSRF tokens, and no visible vulnerabilities or exposed sensitive data. However, it lacks publicly available formal security policies and incident response information, which could improve transparency and preparedness. Security headers are not explicitly detected in the HTML content, suggesting room for enhancement. Analytics usage is moderate with privacy-respecting tools like Matomo, aligned with GDPR compliance. Overall, the security risk is low but could be further mitigated by publishing security policies and adding security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and frameworks.
  2. Provide clear incident response contact information for security issues.
  3. Implement and enforce security headers such as Content-Security-Policy and Strict-Transport-Security.
  4. Consider adding a cookie consent mechanism to enhance user privacy compliance.
  5. Maintain transparency by publishing data retention policies related to analytics and user data.

Technical notes

Notes

The website uses a modern and performant technical stack with asynchronous JavaScript loading, web font preloading, and integration of analytics tools. The HTML is well-structured with semantic elements and accessibility considerations. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. Performance is fast with deferred script loading and optimized images. Technical risks are minimal, but adding security headers and formalizing security documentation would strengthen the infrastructure.
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.
