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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  3. GDPR outside view

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

    • 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 museum operates as a non-profit entity with a business model centered on exhibitions, memberships, events, education, and facility rentals. It maintains partnerships with local art organizations and archives, enhancing its cultural offerings. The domain age and registration details support legitimacy and stability. Revenue streams likely include admissions, memberships, event fees, and store sales. The target market includes local residents, art collectors, families, and educational groups. The museum's digital presence is modern but could benefit from enhanced privacy and security policies to align with regulatory expectations.

Security posture

The website demonstrates a good security baseline with HTTPS and domain transfer protections. However, it lacks DNSSEC, security headers, and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected. The absence of a vulnerability disclosure policy and security.txt file indicates a gap in transparency and readiness for security incidents. Privacy compliance is limited, with no cookie consent mechanism detected. Overall, the security posture is adequate but could be strengthened to improve trust and regulatory compliance.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Publish a clear security policy and incident response contact information on the website.
  5. Develop and publish a vulnerability disclosure policy and security.txt file to improve transparency and security culture.

Technical notes

Notes

The website is built using modern JavaScript frameworks, primarily Next.js and React, ensuring good performance and mobile responsiveness. It uses Cloudinary for image hosting and Google Tag Manager for analytics and marketing. The site is hosted on infrastructure using NS1 DNS servers, indicating a reliable DNS provider. The HTML is well-structured with appropriate meta tags and SEO considerations. Accessibility features are basic but present. There is no evidence of a traditional CMS, suggesting a custom or headless CMS approach. Overall, the technical implementation is solid with opportunities for security and privacy enhancements.
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.
