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

The Real Mary King's Close is a prominent historical tourism attraction located in Edinburgh, UK, specializing in guided tours of a preserved 17th-century street. It holds a strong market position as a leading cultural and heritage site, targeting tourists and history enthusiasts. The website reflects a medium-sized business model focused on ticket sales, events, and visitor engagement through audio guides and accessibility services. Technically, the site employs modern web technologies including Font Awesome, Google Tag Manager, and translation widgets, ensuring good mobile optimization and accessibility. Security posture is adequate with HTTPS enforced and no exposed sensitive data, though explicit security headers could be improved. Privacy compliance is well addressed with visible cookie consent mechanisms and privacy policies. However, the absence of WHOIS data raises concerns about domain registration legitimacy, which should be verified to strengthen trust. Overall, the site is professional, user-friendly, and trustworthy, supporting the business's reputation as a reputable tourism entity.

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

6 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 business operates in the hospitality and tourism sector, offering unique historical experiences that differentiate it in the Edinburgh market. Revenue streams primarily come from ticket sales and event hosting. The company maintains a consistent brand presence with clear navigation and comprehensive visitor information. Partnerships with platforms like TripAdvisor enhance visibility and credibility. The use of multilingual support indicates an international target audience. No parent or subsidiary companies were identified, suggesting an independent operation. The business demonstrates growth potential through event hire and accessibility services, catering to diverse visitor needs.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and controlled use of third-party scripts via Google Tag Manager. No critical vulnerabilities or exposed sensitive information were detected. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could be exploited. There is no public incident response or vulnerability disclosure information, which limits transparency in security management. Privacy compliance is strong with GDPR-aligned policies and consent banners. To enhance security posture, implementing comprehensive security headers and publishing incident response contacts is recommended.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy to mitigate common web attacks.
  2. Verify and update WHOIS domain registration information to improve trust and legitimacy.
  3. Publish a clear incident response policy and contact channels to enhance transparency and readiness.
  4. Conduct regular audits of third-party scripts and tracking services to minimize security risks.
  5. Enhance privacy policy details with explicit data retention and user rights information to strengthen GDPR compliance.

Key observations

  1. Website is fully accessible with rich content about a historical attraction.
  2. No signs of WAF or security blocking.
  3. WHOIS data unavailable, which is unusual and warrants further investigation.
  4. Use of multiple third-party scripts and tracking services with consent mechanisms.
  5. Good accessibility and SEO practices observed.
  6. No explicit security policies or incident response contacts found.
  7. No vulnerability disclosure or security.txt file detected.
Technical notes

Notes

The website uses a modern tech stack with Font Awesome icons, Google Tag Manager for analytics and marketing scripts, and GTranslate for multilingual support. The site loads multiple CSS and JS assets from a semantic UI asset server, indicating a custom or semi-custom front-end framework. Performance is moderate with preloading of critical assets and deferred script loading. Accessibility features such as skip navigation links and ARIA roles are present, supporting usability. SEO is supported by meta tags and Open Graph data. No CMS or hosting provider details were explicitly detected. Technical debt appears low, but security header implementation and WHOIS data gaps represent areas for improvement.
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.
