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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 23 days

      What to do: Renew domain registration before expiration

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

Eventbrite operates in the event ticketing and management sector, serving a broad audience including individual consumers and professional event organizers. Its business model revolves around facilitating event creation and ticket sales, supplemented by marketing tools like Eventbrite Ads. The company maintains a strong partnership ecosystem and a global presence, with localized sites such as the UK domain analyzed here. Revenue streams likely include ticket fees, advertising, and premium event services. The platform's extensive content, social media engagement, and comprehensive support resources indicate a mature and well-established operation with significant market penetration.

Security posture

The website exhibits a mature security posture with HTTPS enforced and integration of consent management frameworks like Transcend. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and others suggests room for enhancement. No direct incident response contacts or vulnerability disclosure policies are publicly available, which could impact transparency and trust. The site avoids exposing sensitive data and uses modern libraries, reducing vulnerability risks. Overall, the security posture is good but could benefit from formalized disclosure and incident response information.

Recommendations

  1. Implement and publish a security.txt file and vulnerability disclosure policy to enhance transparency and encourage responsible reporting.
  2. Add comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen defense-in-depth.
  3. Provide explicit incident response contact information on the security page or footer to improve trust and readiness.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.
  5. Enhance user privacy controls and clearly communicate data retention policies to align with evolving regulations.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on AWS infrastructure with CDN support via Cloudfront. It employs advanced client-side and server-side rendering techniques for performance and SEO benefits. The site is mobile-optimized with responsive design and accessibility considerations. Integration with Google Tag Manager and Transcend Consent Manager indicates a mature approach to analytics and privacy compliance. Performance is fast with preloading and preconnecting resources. Technical risks are minimal, though the lack of some security headers and public vulnerability disclosure could be addressed to reduce potential attack surface.
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.
