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

Leicester Square Theatre is a well-established entertainment venue located in London's West End, offering a diverse program of comedy, cabaret, dance, music, and theatre. The website reflects a professional and polished digital presence, leveraging WordPress CMS with modern technologies such as Google Tag Manager, Facebook Pixel, and Meilisearch for enhanced user experience and marketing capabilities. The site is mobile-optimized, accessible, and SEO-friendly, supporting a broad audience including theatre-goers and members of their LST Priority scheme. Security posture is solid with HTTPS enforced and no visible vulnerabilities, although some security headers could be improved and explicit security policies are absent. The WHOIS data is notably missing or unavailable, which introduces some uncertainty regarding domain registration legitimacy despite the professional site content. Overall, the website demonstrates a mature digital infrastructure suitable for its business model but would benefit from enhanced transparency in domain registration and security policies.

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

4 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 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

  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 theatre operates primarily in the hospitality sector, focusing on live entertainment ticket sales and event hosting. Its market position is strong within the West End theatre community, supported by a membership program and partnerships such as with Stasher for bag storage. The business model relies on direct ticket sales and ancillary services, targeting a general audience interested in cultural and entertainment events. The website's integration with multiple marketing and analytics platforms indicates a data-driven approach to customer engagement and growth. The absence of detailed company registration information online suggests either privacy protection or a new domain registration, which should be monitored for consistency with business operations.

Security posture

The website employs HTTPS and integrates several third-party scripts for analytics and marketing, which are common in modern web environments. Security headers are partially implemented but could be enhanced with CSP, X-Frame-Options, and X-Content-Type-Options for improved protection. No sensitive data exposure or vulnerable libraries were detected in the HTML content. The site lacks explicit security or incident response policies, which is a gap in compliance and transparency. Overall, the security posture is good but could be strengthened by formalizing security policies and improving HTTP header configurations.

Recommendations

  1. Implement comprehensive Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to harden security.
  2. Publish a clear security policy and incident response plan accessible from the website.
  3. Investigate and resolve the missing WHOIS registration data to improve domain trustworthiness.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Enhance transparency by providing business registration details and data protection officer contact information.

Technical notes

Notes

The website is built on WordPress 6.8.2 with a modern tech stack including jQuery, Google Tag Manager, Facebook Pixel, and Meilisearch for search functionality. Performance optimization is handled by WP Rocket, contributing to fast load times and excellent mobile responsiveness. The site uses lazy loading for images and includes accessibility features such as ARIA labels and keyboard navigation support. SEO is well addressed with Yoast SEO plugin metadata and structured data in JSON-LD format. No major technical debt or outdated technologies were identified, indicating a well-maintained infrastructure.
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.
