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

TicketSellers is a UK-based ticket sales platform specializing in tickets for clubs, festivals, live music, sports, family events, and more. Established in 1998, the company has a strong market presence with over 20 million tickets sold and a solid reputation supported by positive customer testimonials and Google reviews. The website is professionally designed with good navigation and mobile optimization, targeting a broad audience of event attendees and music fans. Technically, the site uses modern analytics and error tracking tools such as Google Analytics, Microsoft Application Insights, and Rollbar, hosted partially on Microsoft Azure Blob Storage for static content. Security posture is strong with HTTPS enforced and secure forms, though some security headers and explicit security policies are missing. Privacy and cookie policies are present and GDPR compliant, enhancing user trust. However, the WHOIS data for the subdomain ww2.theticketsellers.co.uk is unavailable and indicates the domain is not officially registered, suggesting it may be a staging or internal environment rather than a public-facing domain. Overall, the site is trustworthy, professional, and secure with room for improvement in security headers and incident response transparency.

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.

    • 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. 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.

  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 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

TicketSellers operates in the entertainment sector, providing ticket sales and event promotion services primarily in the UK. Their business model focuses on online ticket sales with additional services such as ticket printing and electronic door entry systems. The company targets a diverse customer base including club-goers, festival attendees, families, students, and sports fans. Their market position is strong, supported by decades of experience and a large volume of ticket sales. Partnerships with platforms like Eventree, TKT.to, and Citizen Ticket indicate a robust ecosystem. The company maintains active social media presence and customer engagement through mailing lists and testimonials. Growth indicators include continuous event category expansion and digital marketing investments. The company size is medium with a well-established brand and consistent content quality.

Security posture

The website demonstrates a mature security posture with HTTPS enforced site-wide, secure form handling with anti-forgery tokens, and use of advanced monitoring tools like Rollbar and Application Insights. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the overall security hardening. No public security policy or incident response information is available, which could impact transparency and user trust in case of incidents. The lack of exposed sensitive data and no visible vulnerable libraries are positive indicators. The WHOIS data gap for the subdomain analyzed is a concern but does not affect the main domain's legitimacy. Overall, the security posture is good but could be enhanced with additional headers and published policies.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to improve security hardening.
  2. Publish a dedicated security policy and incident response page to increase transparency and user trust.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Provide clear and verified company contact information including support emails and phone numbers for better customer and security incident communication.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics (Universal and GA4), Microsoft Application Insights for telemetry, Rollbar for error tracking, jQuery, SweetAlert for UI alerts, Font Awesome for icons, and Google Fonts for typography. Static assets are hosted on Microsoft Azure Blob Storage, indicating cloud hosting infrastructure. The site is mobile optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate with no major issues detected. The site lacks a detected CMS, suggesting a custom or proprietary platform. Technical debt appears low, but improvements in accessibility and security headers are recommended 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.
