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 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 business operates in the non-profit sector, organizing one of the world's largest fun runs and charity fundraising events. Its competitive advantage lies in its long history, large participant base, and strong partnerships, including naming rights with Voltaren and integration with fundraising platforms like Grassrootz. Revenue streams likely include entry fees, sponsorships, and fundraising commissions. The target audience includes runners, charity supporters, and the Sydney community. Growth indicators include increasing fundraising targets and participant engagement. The partnership ecosystem includes Ironman, Grassrootz, and Rebelsport, enhancing event reach and participant support.

Security posture

The website maintains a good security posture with HTTPS enforced and use of reputable third-party services for analytics and advertising. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. No incident response or security contact information is provided, which could hinder timely reporting and handling of security incidents. The cookie consent mechanism aligns with privacy regulations, but continuous monitoring of third-party scripts is recommended to mitigate supply chain risks. Overall, the security maturity is moderate to good, with room for improvement in header implementation and incident response readiness.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and responsiveness.
  3. Regularly audit and update third-party scripts and libraries to minimize vulnerabilities from external dependencies.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider adding a terms of service page to clarify user rights and responsibilities, improving legal compliance and user trust.

Technical notes

Notes

The website is built on a modern tech stack including Bootstrap for responsive design, Font Awesome for icons, and Google services for analytics and optimization. It uses Cloudflare Zaraz for tag management and CDN delivery, improving performance and security. The CMS appears to be SilverStripe based on URL patterns and form naming conventions. Performance is moderate with video backgrounds and multiple scripts, but mobile optimization is good. The site uses structured data and Open Graph tags for SEO. Technical debt is low, but improvements in security headers and accessibility could be made to reduce risks and enhance compliance.
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.
