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

Cannes Lions International Festival of Creativity is a globally recognized event organized by Informa PLC, serving as the premier gathering for the creative marketing and advertising community. The website promotes the upcoming 2026 festival, highlighting key offerings such as awards, learning programs, partnerships, and impact initiatives. The business model revolves around event passes, sponsorships, and educational content, positioning Cannes Lions as a market leader in the media and advertising sector. Technically, the website leverages modern frameworks like Next.js and React, integrates multimedia content via Vimeo, and employs error monitoring through Raygun. The site is well-optimized for mobile devices, accessible, and SEO-friendly, reflecting a mature digital infrastructure. Security is robust with HTTPS enforcement and standard security headers, though explicit security policies and incident response details are not publicly documented. Overall, the security posture is strong with no evident vulnerabilities or suspicious activity. Privacy compliance is well addressed with comprehensive policies and cookie consent mechanisms. The absence of public WHOIS data suggests privacy protection, which is justified for a large media entity. The site maintains high professionalism and trustworthiness, supported by consistent branding and active social media presence. Strategic recommendations include publishing detailed security and incident response policies, establishing a vulnerability disclosure program, and enhancing direct security contact channels to further strengthen trust and compliance.

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

2 findings rated critical or high. Fix these first.

  1. 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

  2. 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.

Business context

Business profile

Cannes Lions operates as a flagship event under Informa PLC, targeting creative professionals and marketers worldwide. Its competitive advantage lies in its prestigious awards and comprehensive festival experience, including learning and partnership opportunities. Revenue streams include ticket sales, sponsorships, and educational programs. The company demonstrates strong growth potential through digital content offerings and global networking. Partnerships with related domains like the Lions Store and The Work platform expand its ecosystem. The brand's global recognition and association with Informa PLC reinforce its market position and operational credibility.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of security headers, and integration of error monitoring tools. No exposed sensitive data or vulnerable libraries were detected. However, the lack of a publicly available security policy and incident response information indicates room for improvement in transparency and preparedness. There are no signs of phishing or malware. Privacy policies and cookie consent mechanisms align with GDPR requirements, but explicit security contact channels are absent, which could hinder incident reporting and response efficiency.

Recommendations

  1. Publish a comprehensive security policy outlining frameworks and controls in place.
  2. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Provide clear security contact information for incident reporting and response.
  4. Regularly review and update third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance user trust by detailing data retention and privacy practices explicitly.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring server-side rendering and good performance. It uses Contentful as a CMS, Vimeo for video content, and Raygun for error monitoring. Google Tag Manager is employed for analytics and marketing tracking. The site is mobile-optimized and accessible, with proper meta tags for SEO. Performance is moderate, likely due to rich multimedia content. There is no indication of legacy or vulnerable technologies. Opportunities exist to improve hosting transparency and implement advanced security headers or CSP policies for enhanced protection.
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.
