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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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"

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 operates as a non-profit cultural institution with a focus on preserving and showcasing African ethnographic collections. Its market position is regional, targeting visitors and educational groups interested in history and culture. The business model revolves around exhibitions and cultural education rather than commercial sales. The website reflects consistent branding and professional presentation, with partnerships indicated by links to local tourism and web development sites. Growth potential lies in expanding digital presence and compliance with privacy regulations to enhance visitor trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and CSRF tokens implemented in forms. Use of Google reCAPTCHA on forms helps mitigate spam. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosures or incident response contacts are published, which limits transparency and readiness. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the security posture is functional but could be strengthened by adopting comprehensive policies and security headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Implement security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Add an incident response contact email (e.g., security@ or abuse@) to enhance transparency.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance accessibility features and provide clear data retention policies for collected user data.

Technical notes

Notes

The website uses a modern tech stack including Google Maps API for interactive maps, Google Fonts for typography, and likely Ruby on Rails as backend framework indicated by authenticity tokens in forms. The front-end uses Bootstrap CSS classes for responsive design. Performance is moderate with no obvious blocking scripts. Mobile optimization is good, and SEO meta tags are properly set. However, no advanced analytics or tracking tools are detected, which limits marketing insights. The site lacks some security headers and formal privacy compliance mechanisms, representing technical debt and compliance risk.
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.
