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

LayerZero Scan is a specialized blockchain interoperability message explorer focused on providing users and developers with detailed insights into messages and transactions sent through the LayerZero protocol. The website positions itself as a niche tool within the blockchain ecosystem, targeting blockchain developers, crypto users, and ecosystem participants who require omnichain message tracking and analytics. The business model revolves around offering data exploration and analytics services related to LayerZero's interoperability protocol. The site is well-branded and consistent with LayerZero's identity, though it lacks explicit company contact details and some compliance features. Technically, the website is built on a modern stack including Next.js and React, hosted on Vercel, and uses Google Tag Manager, PostHog, and Vercel Analytics for tracking. The site is performant, mobile-optimized, and SEO-friendly. However, it lacks some advanced accessibility features and explicit security headers. Privacy compliance is basic, with a privacy policy and terms of use present but no cookie consent mechanism. From a security perspective, the site enforces HTTPS and does not expose sensitive data or vulnerable libraries visibly. However, it lacks explicit security policies, incident response information, and vulnerability disclosure mechanisms. The WHOIS data is consistent and trustworthy, matching the website's business focus. No WAF or blocking mechanisms were detected, and the site content is safe with no adult or questionable material. Overall, the website demonstrates a solid technical foundation and business focus but could improve in privacy compliance, security transparency, and contact information availability to enhance trust and compliance posture.

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

5 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"

    • 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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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

LayerZero Scan operates in the blockchain technology sector, providing a specialized service for omnichain message exploration related to the LayerZero interoperability protocol. Its market positioning is niche, serving blockchain developers and crypto users who need detailed transaction and message analytics across multiple chains. The business model likely involves offering free or subscription-based access to analytics tools and data exploration services. The company leverages partnerships with LayerZero Network and integrates with their ecosystem, as evidenced by linked domains and social media presence. Growth indicators include active analytics features and ecosystem tools, though the site is relatively small in scale. The absence of direct contact information and limited compliance features suggest a startup or early-stage operation focused on technical delivery rather than broad commercial outreach.

Security posture

The website's security posture is moderate to good. HTTPS is enforced, ensuring encrypted communications. No visible sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security hardening. There is no publicly available security policy or incident response information, which limits transparency and preparedness perception. The lack of a vulnerability disclosure policy or security.txt file means that security researchers have no formal channel to report issues. Privacy compliance is basic, with a privacy policy present but no cookie consent mechanism, which may pose GDPR compliance risks. Overall, while the site is not exposed to obvious vulnerabilities, improvements in security best practices and compliance transparency are recommended.

Recommendations

  1. Implement and publish a comprehensive security policy including incident response procedures.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Introduce a cookie consent banner/mechanism to improve GDPR compliance and user privacy transparency.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  5. Provide clear and accessible contact information for business and security inquiries to improve trust and communication.

Technical notes

Notes

The website is built using a modern React and Next.js framework, hosted on Vercel, which provides scalable and performant infrastructure. It uses Google Fonts for typography and integrates analytics tools including Google Tag Manager, PostHog, and Vercel Analytics for user behavior tracking. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. However, accessibility features are basic and could be enhanced. No CMS is detected, indicating a custom or static site generation approach. The absence of advanced security headers and privacy compliance mechanisms indicates areas for technical improvement. Overall, the technical infrastructure is solid and modern but could benefit from additional security and privacy enhancements.
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.
