Messari's Mainnet 2024 website serves as the official platform for the largest annual crypto conference in New York City, targeting professionals, institutional investors, and policymakers in the blockchain and crypto industry. The event is positioned as a key networking and knowledge-sharing opportunity, featuring a robust lineup of speakers and sponsors. The website leverages the Bizzabo event platform for ticketing and event management, integrating multiple analytics and marketing tools to optimize user engagement and event promotion. Privacy and compliance are addressed with accessible privacy and terms of service documents, alongside cookie consent mechanisms. Security posture is solid with HTTPS and no evident vulnerabilities, though security headers could be improved. WHOIS data is unavailable due to privacy protection, which is typical for event domains and does not detract from the site's legitimacy. Overall, the site is professional, well-structured, and trustworthy, supporting Messari's market position in the crypto event space.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Messari operates Mainnet as a flagship event that bridges crypto innovators with institutional capital and policymakers, enhancing its competitive advantage in the crypto conference market. The business model centers on event ticket sales, sponsorships, and brand positioning within the crypto ecosystem. The website reflects a mature digital presence with strategic partnerships (notably Bizzabo) and a comprehensive marketing stack. The target audience includes crypto professionals, investors, and decision makers, indicating a B2B and B2C hybrid approach. Growth indicators include a strong speaker lineup and integration with Messari's broader product suite. The partnership ecosystem is evident through linked domains and sponsor mentions, reinforcing the event's industry relevance.

Security posture

The website demonstrates a good security posture with enforced HTTPS, absence of exposed sensitive data, and implementation of cookie consent aligned with GDPR. The use of reputable third-party analytics and marketing tools is balanced with privacy considerations. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for enhancement. No vulnerability disclosures or incident response information is present, which could be improved to bolster trust. The WHOIS privacy protection is justified and common for event domains, posing no immediate risk. Overall, the site is secure for its purpose but could benefit from additional security best practices and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a vulnerability disclosure program and security.txt file to encourage responsible reporting and demonstrate security maturity.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize security risks.

Technical notes

Notes

The website is built on the Bizzabo event platform, integrating modern analytics and marketing technologies such as Google Tag Manager, Microsoft Clarity, Mixpanel, and Facebook Pixel. The site is mobile-optimized with responsive design and uses CDN-hosted assets for performance. The presence of multiple tracking and analytics scripts indicates a data-driven approach to user engagement. Performance is moderate, with potential improvements in load speed and accessibility. The technical stack is modern and appropriate for an event site, though some technical debt may exist in the form of missing security headers and limited accessibility features. Hosting details are not explicit but likely managed by Bizzabo or cloud providers.
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.
