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

3 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 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

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

Clarion Events holds a strong market position as a leading private event organiser with a diverse portfolio of over 125 events and media brands. Their business model focuses on creating value through large-scale, sector-specific events and digital engagement platforms. The company targets businesses and professionals across various industries globally, supported by 12 international offices. The presence of detailed gender pay gap reports and sustainability information indicates a mature corporate governance approach. Their partnership ecosystem includes regional sites such as us.clarionevents.com, enhancing their market reach. The company’s longevity and domain age reinforce their credibility and stability in the market.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and no exposed sensitive data. Use of multiple analytics and marketing tools is balanced with privacy compliance via OneTrust cookie consent. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms such as security.txt suggests room for improvement in transparency and readiness. No outdated or vulnerable libraries were detected, and no WAF or blocking mechanisms interfere with accessibility. Security headers were not explicitly detected in the HTML content, which could be enhanced. Overall, the security posture is good but could benefit from formal documentation and additional headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information, including abuse and security email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Review and enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy and security risks.

Technical notes

Notes

The website is built on the ASP.events platform, leveraging common web technologies such as jQuery and Font Awesome for UI components. It integrates multiple third-party analytics and marketing tools including Google Analytics, Hotjar, Visual Website Optimizer, and OneTrust for cookie management. The site is mobile responsive and accessible, with good SEO practices including meta tags and structured data in JSON-LD format. Performance is moderate, with asynchronous loading of scripts to optimize user experience. The domain is stable and well-managed with prohibitive domain statuses to prevent unauthorized changes. Hosting provider details are not explicitly available from the content. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
