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

Winter Run is a non-profit fundraising platform supporting the Cancer Research UK London Winter Run event, a 10k running challenge through London landmarks. The website serves as a hub for participant registration, fundraising, and donation tracking, leveraging a modern technical infrastructure including jQuery, Bootstrap, and various JavaScript libraries. The site is hosted on Amazon Cloudfront CDN and integrates Google Analytics and Facebook Pixel for marketing and analytics purposes. Security posture is strong with HTTPS enforced and no visible vulnerabilities, though security headers and formal security policies are not published. Privacy compliance is well addressed with a clear cookie consent mechanism and a comprehensive privacy policy linked to Cancer Research UK's main site. WHOIS data for the exact domain is unavailable due to domain naming rules, indicating it is likely a subdomain or alias, but the website's branding and content strongly associate it with the reputable Cancer Research UK organization. Overall, the site is professional, trustworthy, and well-optimized for its audience.

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

3 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

  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 Winter Run website positions itself as a key fundraising platform within the charity and non-profit sector, specifically supporting Cancer Research UK. Its business model revolves around event-driven fundraising, engaging runners and donors through online profiles, leaderboards, and donation tracking. The platform benefits from partnerships with Cancer Research UK and related event sites, enhancing its credibility and reach. The use of a specialized fundraising CMS (Funraisin) and integration with support portals like Zendesk indicates a mature operational setup. The target audience includes charity supporters, runners, and donors primarily in the UK. The site demonstrates consistent branding and a clear focus on fundraising goals, with a medium-sized organizational footprint.

Security posture

The website demonstrates a solid security posture with HTTPS enforced site-wide and no exposed sensitive data in the HTML content. It employs standard security best practices such as cookie consent and uses reputable third-party analytics and marketing tools. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or suspicious scripts were detected in the analysis. The WHOIS data anomaly does not directly impact security but suggests the domain is a subdomain or alias, which is common in event fundraising platforms. Overall, the security maturity is good but could be enhanced with formal policies and additional HTTP security headers.

Recommendations

  1. Implement HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a security.txt file at the root domain to facilitate vulnerability disclosures.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.

Technical notes

Notes

The website is built on a modern and robust technical stack featuring jQuery, Bootstrap 3, OwlCarousel, Slick Carousel, and other JavaScript libraries for UI and UX enhancements. It uses the Funraisin fundraising platform CMS, which is specialized for charity event management. Hosting is via Amazon Cloudfront CDN, ensuring good global performance and availability. The site is mobile optimized with responsive design and includes SEO best practices such as meta tags and Open Graph data. Performance is moderate, with potential improvements in loading speed by optimizing scripts and assets. The technical implementation is solid with room for modernization in accessibility and security headers.
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.
