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 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 Lyceum Theatre holds a strong position in Edinburgh's cultural sector as a medium-sized non-profit organization. Its business model revolves around live performances, memberships, and community participation. The company benefits from partnerships with local cultural bodies and government entities, enhancing its credibility and reach. Revenue streams likely include ticket sales, memberships, donations, and grants. The website supports these operations with integrated ticketing and marketing tools. Growth indicators include a well-maintained digital presence and active social media engagement. Strategic observations suggest continued focus on digital modernization and enhanced security practices to maintain trust and compliance.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and a cookie consent mechanism aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of certain security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. The use of third-party scripts necessitates ongoing monitoring for vulnerabilities. Incident response and security policy information are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security posture is solid but could benefit from additional hardening and documented policies.

Recommendations

  1. Implement Content-Security-Policy and X-Frame-Options headers to enhance protection against common web attacks.
  2. Publish a security policy and incident response plan on the website to improve transparency and preparedness.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  4. Enhance data retention disclosures related to analytics and tracking cookies to improve privacy compliance.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Notes

The website uses a modern tech stack including JavaScript frameworks, CSS Grid for layout, and Flickity for carousel functionality. It integrates with Spektrix for ticketing and uses Google Tag Manager and Hotjar for analytics and user behavior tracking. The site is mobile-optimized with responsive design and accessibility features such as skip links. Performance is moderate, with room for optimization in loading times. Hosting details are limited, but the domain registrar is Tucows Inc. The site employs a service worker for progressive web app capabilities. Technical risks include reliance on multiple third-party scripts which require vigilant security management.
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.
