0–100, higher is better. How it is calculated

The North East Land Sea and Air Museums (NELSAM) is a volunteer-run heritage museum located in Sunderland, UK, dedicated to preserving and showcasing 100 years of transport history including aircraft, military vehicles, and electric traction. The museum operates as a registered charity and limited company, offering exhibits, events, and educational programs to local visitors, tourists, and history enthusiasts. The website reflects a well-maintained digital presence with clear navigation, event information, and social media integration. Technically, the site uses modern frontend technologies such as Tailwind CSS and Lucide Icons, with Google Analytics and Tag Manager for tracking, and a cookie consent mechanism ensuring privacy compliance. Security posture is moderate with HTTPS implied but lacking explicit security headers or published security policies. The WHOIS data is unavailable due to a domain naming rules error, which is unusual but the website content and external trust signals support legitimacy. Overall, the site is professional, informative, and trustworthy, though improvements in security transparency and WHOIS data clarity are recommended.

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. 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 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';…

  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

NELSAM occupies a niche market position as a regional non-profit museum focused on transport and military history. Its competitive advantage lies in unique exhibits such as the Avro Vulcan B2 Bomber and military vehicles, supported by strong community engagement and multiple TripAdvisor awards. The business model relies on visitor admissions, donations, fundraising campaigns, and volunteer support. The museum targets families, history enthusiasts, and local communities, with a clear emphasis on education and preservation. Partnerships with regional transport initiatives and crowdfunding platforms enhance its outreach and funding capabilities. The website's content and event programming indicate active growth and community involvement, positioning NELSAM as a respected cultural institution in the North East of England.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is used, and a cookie consent banner is implemented, indicating awareness of privacy regulations. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, and there is no published security policy or incident response contact information. No vulnerabilities or exposed sensitive data were found in the content. The absence of a vulnerability disclosure or security.txt file suggests limited formal security communication. Overall, while the site is not at high risk, enhancing security headers, publishing security policies, and establishing incident response channels would improve the security posture and compliance.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Clarify domain registration details or resolve WHOIS inconsistencies to strengthen domain trustworthiness.

Technical notes

Notes

The website employs a modern frontend stack with Tailwind CSS for styling and Lucide Icons for vector graphics. Google Analytics and Google Tag Manager are used for analytics and marketing tracking. The site is responsive and mobile-optimized with good navigation clarity and user experience. Cookie consent is managed via CookieScript, ensuring compliance with privacy regulations. No CMS or hosting provider details were detected. Performance is moderate with no major issues visible. Accessibility features are basic but present. The site could benefit from enhanced security headers and more explicit technical metadata. Overall, the technical implementation supports the museum's business goals effectively but has room for security and performance optimizations.
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.
