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

Tattersalls is a historic and leading bloodstock auctioneer based in Newmarket, UK, with a legacy dating back to 1766. The company operates multiple auction venues and online platforms, serving a specialized market of horse owners, buyers, and industry professionals. Their website reflects a mature digital presence with comprehensive content, clear navigation, and strong branding consistent with their market position. Technically, the website is built on WordPress with modern plugins and integrations such as Yoast SEO, Google Tag Manager, and reCAPTCHA, indicating a well-maintained infrastructure. The site is mobile-optimized, accessible, and SEO-friendly, supporting a positive user experience. Security measures include HTTPS enforcement and form protection, though some security headers could be improved. From a security and compliance perspective, the site implements cookie consent and privacy policies aligned with GDPR requirements. However, explicit security policies and incident response contacts are absent, and WHOIS data is unavailable, which slightly impacts transparency. No critical vulnerabilities or suspicious content were detected. Overall, Tattersalls presents a professional and trustworthy online presence with minor areas for security enhancement. The missing WHOIS data warrants monitoring but does not currently undermine the site's legitimacy.

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. 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

  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. 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

Tattersalls holds a dominant position in the bloodstock auction industry, leveraging its historic brand and multiple sales venues including Cheltenham, Ireland, and online platforms. Their business model centers on auctioning thoroughbred horses, supported by detailed sales data, live bidding services, and sponsorship programs. The company targets a niche but global audience of equine professionals and enthusiasts. Partnerships with related organizations and a strong social media presence enhance their ecosystem. The website's comprehensive content and consistent branding support customer engagement and trust, indicating a mature and stable business operation.

Security posture

The website demonstrates a solid security posture with HTTPS, reCAPTCHA integration, and cookie consent mechanisms. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts represent gaps in transparency and defense-in-depth. The missing WHOIS data reduces domain registration transparency but is likely due to privacy or registry issues rather than malicious intent. No vulnerabilities or exposed sensitive data were found. Overall, the security maturity is good but could be improved by adopting additional headers, publishing security policies, and implementing vulnerability disclosure processes.

Recommendations

  1. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a formal security policy and incident response contact information to improve transparency and preparedness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate risks from outdated software.
  5. Monitor domain WHOIS information and consider clarifying registration details to improve trust and transparency.

Technical notes

Notes

The website is built on a modern WordPress platform with a well-structured theme and use of popular plugins such as Yoast SEO for search optimization and Constant Contact for email marketing. JavaScript libraries include jQuery and integrations with Google Tag Manager and WonderPush for analytics and push notifications. The site is responsive and optimized for mobile devices, with good accessibility features. Performance is moderate, with room for improvement in loading speed. The technical stack is appropriate for the business needs, but ongoing maintenance and security updates are essential to sustain operational stability.
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.
