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. 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

  2. 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"

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 Kenton Theatre holds a strong position as a local cultural hub with a focus on community engagement and education through theatre. Its business model is typical for non-profits in the arts sector, combining event ticketing with donations and sponsorships. The presence of sponsors and a registered charity status enhances credibility. The theatre leverages social media and digital marketing tools to reach its audience. The website's content and structure support its mission and provide clear pathways for engagement, ticket purchase, and donations. Growth potential lies in expanding youth programs and digital outreach. Partnerships with local businesses and legal firms indicate a supportive ecosystem. No parent or subsidiary companies are identified, confirming its independent community status.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and DNSSEC enabled, reducing risks of DNS spoofing. The use of hCaptcha on forms helps mitigate spam and automated abuse. Cookie consent is implemented, supporting privacy regulations. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the analysis. Security headers beyond DNSSEC are not explicitly mentioned, which could enhance protection against common web attacks. Overall, the security posture is adequate for a community theatre website but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  2. Publish a dedicated security policy page including incident response procedures and security contact information to improve transparency and trust.
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility compliance to ensure inclusivity for all users.
  5. Regularly review and update third-party scripts and plugins to mitigate risks from vulnerable libraries.

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Yoast SEO, Google Analytics, and hCaptcha.

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.
