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

A.S.O. UK is a UK-based event organizer specializing in sporting events such as marathons, runs, triathlons, and cycling events. The website presents a professional and consistent brand image with clear navigation and relevant content targeting sports participants and enthusiasts in the UK. The business model focuses on event organization and management, with additional opportunities for volunteers and event crew recruitment. The company appears to be newly established in 2024, with a small organizational size and no parent or subsidiary companies identified. Technically, the website is built on WordPress with a modern tech stack including jQuery, Yoast SEO, Google Tag Manager, and several plugins for forms and media display. The site is mobile-optimized and performs moderately well, with good SEO practices and basic accessibility features. Hosting is inferred to be through 123-Reg Limited, consistent with the registrar information. From a security perspective, the site enforces HTTPS and has domain status protections to prevent unauthorized changes. However, DNSSEC is not enabled, and no explicit security headers were detected in the HTML content. There are no visible vulnerabilities or exposed sensitive data. Privacy compliance is addressed with clear privacy and cookie policies, and Google Analytics is used with consent mechanisms denying ad and analytics storage by default. Overall, the website is safe, professional, and trustworthy with no adult or explicit content. The domain registration details align well with the website's business claims, supporting legitimacy. Recommendations include enabling DNSSEC, adding security headers, and publishing explicit security and incident response policies to enhance trust and security posture.

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

5 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 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';…

  2. 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

  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
    • 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

A.S.O. UK operates in the event management sector focusing on sporting events in the UK. The company leverages digital channels to promote events and recruit volunteers, indicating a community-oriented business model. The presence of multiple event pages and opportunities sections suggests diversified revenue streams including event fees, sponsorships, and partnerships. The company maintains a consistent brand and uses social media for engagement, primarily Facebook and Twitter. The new domain registration in 2024 aligns with a startup or recently rebranded entity. The lack of parent or subsidiary companies suggests independent operation. The business targets active individuals interested in running, cycling, and triathlon events, positioning itself as a niche organizer in the UK sports event market.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and domain status protections in place. The absence of DNSSEC and security headers represents areas for improvement. No direct incident response or security policy information is published, which may limit transparency and readiness perception. The use of Google Tag Manager and analytics is managed with consent denial for ad and analytics storage, reflecting privacy-conscious practices. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate for a small event organizer but could benefit from enhanced DNS security, security headers, and published security policies to improve resilience and trust.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to mitigate common web attacks.
  3. Publish a dedicated security policy and incident response plan on the website to increase transparency and preparedness.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly review and update third-party plugins and scripts to minimize vulnerabilities and maintain performance.

Technical notes

Notes

The website is built on a WordPress CMS platform using a modern and widely supported technology stack including jQuery and Yoast SEO for optimization. It integrates Google Tag Manager for analytics and tracking, with consent mechanisms to limit data collection. The site uses several plugins for enhanced functionality such as Formidable Forms and Instagram Feed. Hosting appears to be managed by 123-Reg Limited, a reputable UK registrar and hosting provider. Performance is moderate with good mobile optimization and basic accessibility. The site structure and metadata are well implemented, supporting SEO and social media integration. Technical risks include lack of DNSSEC and missing security headers, which should be addressed to reduce attack surface and improve security posture.
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.
