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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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 company holds a strong market position as the UK's leading mass participation events organizer under the umbrella of Amaury Sport Organisation. Its business model focuses on organizing large-scale sporting events and bespoke corporate events, generating revenue through participant fees and corporate partnerships. The target customer segments include sports enthusiasts, charity participants, and corporate clients. The partnership ecosystem is robust, linking to official event websites and recognized brands. Growth indicators include recent domain registration aligned with business launch and active event promotion. Strategic observations highlight the importance of maintaining strong digital presence and expanding corporate event offerings to diversify revenue streams.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and domain status protections preventing unauthorized domain changes. However, the absence of DNSSEC and lack of published security or incident response policies indicate areas for improvement. The use of Google Consent Mode with denied ad and analytics storage reflects a privacy-conscious approach. No exposed sensitive data or vulnerable libraries were detected. The security culture could be enhanced by publishing a vulnerability disclosure policy and implementing additional security headers. Overall, the security posture is adequate for the business type but could be strengthened to mitigate emerging threats and compliance requirements.

Recommendations

  1. Enable DNSSEC to enhance domain name system security and prevent DNS spoofing.
  2. Publish a formal security policy and incident response contact information to improve transparency and readiness.
  3. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly review and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a WordPress CMS platform using a modern tech stack including Yoast SEO, jQuery, Slick Slider, and Google Tag Manager. The site is hosted likely via 123-Reg Limited, consistent with the registrar information. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well implemented with proper meta tags, Open Graph, and JSON-LD structured data. The site uses video content and interactive elements enhancing user engagement. Technical risks include reliance on multiple third-party scripts and lack of DNSSEC. Opportunities exist to improve accessibility and security headers to reduce technical debt and enhance resilience.
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.
