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 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. 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 museum holds a dominant position in Norway's cultural sector as the largest institution of its kind. Its business model is non-commercial, focusing on public service, education, and cultural preservation. Revenue streams likely include government funding, ticket sales, memberships, and possibly donations or sponsorships. The website supports these functions with ticketing links, membership information, and educational resources. The partnership ecosystem includes recognized privacy and marketing service providers such as CookieInformation, HubSpot, Google, and Microsoft. The museum's digital strategy emphasizes user privacy and compliance, reflecting a strong governance culture. Growth indicators include active content updates, multilingual support, and integration of modern analytics tools.

Security posture

The website exhibits a solid security posture with HTTPS enforced and multiple security headers implemented, reducing common web vulnerabilities. The cookie consent mechanism is robust, offering granular user control and transparency about third-party cookies and data processors. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency and may hinder rapid incident communication. No exposed sensitive data or vulnerable libraries were detected in the provided content. The use of reputable cloud hosting and content delivery networks further strengthens security. Overall, the site aligns well with GDPR and general web security best practices but could improve by publishing explicit security governance documents and contact channels for security incidents.

Recommendations

  1. Publish a dedicated security policy and incident response information page to enhance transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Provide clear contact information for security and privacy concerns, including dedicated email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Optimize website performance further to improve load times and user experience, especially on mobile devices.

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.
