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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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"

    • 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';…

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 website reflects a well-established charity event with strong market positioning as the UK's leading 10k run for cancer research fundraising. The business model focuses on event organization and fundraising, targeting a wide demographic of runners and supporters. Partnerships with recognized organizations and service providers enhance credibility and operational capacity. The site demonstrates effective use of digital marketing and analytics tools to optimize user engagement and fundraising outcomes. Growth indicators include consistent event updates, social media activity, and community involvement. Strategic observations highlight the importance of maintaining data privacy compliance and enhancing security to protect user trust.

Security posture

The website exhibits a mature security posture with HTTPS enabled and use of Cloudflare for bot management. Cookie consent is managed via CookieYes, providing granular user control. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. Incident response and vulnerability disclosure mechanisms are not evident, indicating potential gaps in security governance. Compliance with GDPR is supported by privacy and cookie policies. Overall, the security maturity is good but could benefit from enhanced header policies and formal incident response documentation.

Recommendations

  1. Implement Content-Security-Policy and other security headers to mitigate common web attacks.
  2. Establish and publish a vulnerability disclosure policy or security.txt file to improve transparency.
  3. Add explicit incident response contact information to facilitate security reporting.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update accordingly.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

It uses specialized plugins for Instagram feeds and 3D flipbooks, enhancing content engagement. Performance is moderate with good mobile optimization and SEO practices.

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.
