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

3 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. GDPR outside view

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

    • 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

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 Wellcome Collection operates as a non-profit entity in the cultural and educational sector, providing free access to museum exhibitions, library resources, and educational events. Its business model focuses on public engagement and knowledge dissemination rather than commercial revenue. The organization targets diverse audiences including researchers, students, and the general public interested in health and human experience. The website supports this with rich multimedia content and event promotion. Partnerships and related domains include the Wellcome Trust and developer resources, indicating a broader ecosystem. The institution's reputation and longevity provide competitive advantages in the cultural sector. Growth indicators include active event programming and publishing activities. The website's integration of analytics and marketing tools supports audience engagement and outreach strategies.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and use of reputable analytics platforms that provide opt-out mechanisms. Cookie consent is implemented in compliance with GDPR standards. However, DNSSEC is not enabled, representing a minor security gap in DNS integrity. No explicit security policy or incident response contact information is publicly available, which could be improved to enhance transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts is managed with consent, but ongoing monitoring is recommended to mitigate risks. Overall, the security maturity is good for a non-profit cultural institution, balancing user privacy and operational needs.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Publish a clear security policy and incident response contact details on the website.
  3. Consider implementing a security.txt file to facilitate vulnerability disclosures.
  4. Regularly audit and update third-party scripts and analytics tools to mitigate vulnerabilities.
  5. Maintain and update cookie consent mechanisms to comply with evolving privacy regulations.

Technical notes

Notes

The website is built using modern web technologies including React with Next.js framework and Prismic CMS for content management. Hosting is provided by Amazon AWS, ensuring scalability and reliability. Performance is optimized with lazy loading of images and asynchronous loading of scripts. Accessibility features such as skip links, ARIA roles, and BSL interpreted events are present, reflecting good inclusivity practices. SEO is well addressed with meta tags, Open Graph, and Twitter card metadata. Analytics and marketing tools are integrated with user privacy in mind. The technical infrastructure supports a fast, responsive, and user-friendly experience suitable for a diverse audience. Opportunities for modernization include enabling DNSSEC and enhancing security policy transparency.
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.
