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

BNB Chain is a community-driven decentralized blockchain ecosystem focused on enabling Web3 decentralized applications powered by the BNB token. The website positions itself as a leading platform for the next billion Web3 users, targeting developers and blockchain enthusiasts. The business model revolves around providing blockchain infrastructure and fostering a decentralized ecosystem for dApps. The market position is strong within the blockchain technology sector, with a large-scale presence indicated by the professional website and branding. Technically, the website employs modern web technologies including React, Next.js, and Chakra UI, with integrations for analytics and user behavior tracking such as Google Analytics and Hotjar. The site is mobile optimized and demonstrates good design quality and user experience. However, some technical improvements could be made in security headers and explicit privacy compliance features. From a security perspective, the site uses HTTPS and has Google site verification, but lacks visible security headers and explicit privacy or cookie policies. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data is unavailable due to a malformed response, likely due to privacy protection, which is common in blockchain domains but reduces transparency. Overall, the website is professional and trustworthy in appearance, but would benefit from enhanced privacy compliance and clearer contact and security policies to improve user trust and regulatory adherence.

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. 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 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. 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

  4. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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

BNB Chain operates in the blockchain technology sector, focusing on decentralized applications and Web3 infrastructure. Its competitive advantage lies in its community-driven approach and association with the BNB token ecosystem. The business model is platform-based, providing blockchain infrastructure and developer tools. Revenue streams likely include transaction fees, ecosystem partnerships, and token-related activities. The target customers are Web3 developers, blockchain projects, and users interested in decentralized finance and applications. Growth indicators include a modern web presence and active social media engagement. The partnership ecosystem is not explicitly detailed on the site. Strategic observations suggest a focus on scaling Web3 adoption and maintaining a decentralized governance model.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and Google site verification in place. However, it lacks explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended best practices. No visible vulnerabilities or exposed sensitive data were found. Privacy compliance is weak due to the absence of privacy and cookie policies, which could pose regulatory risks under GDPR and similar frameworks. Incident response and security contact information are not provided, limiting transparency. The use of third-party analytics and tracking scripts introduces moderate user tracking. Overall, the security posture is adequate but could be improved with enhanced policies and technical controls.

Recommendations

  1. Implement and prominently display comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen security posture.
  3. Provide clear contact information for security incidents, including dedicated security or abuse email addresses.
  4. Review and minimize third-party tracking scripts to reduce user tracking and enhance privacy compliance.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve transparency.

Technical notes

Notes

The website is built using modern frontend technologies including React and Next.js, styled with Chakra UI, indicating a contemporary and maintainable codebase. It leverages Google Tag Manager for analytics and Hotjar for user behavior tracking. The site is mobile responsive and optimized for good user experience. Performance is moderate, with deferred loading of scripts and preloading of critical CSS. No CMS was detected, suggesting a custom or static site generation approach. Hosting provider details are not evident from the HTML. Technical risks include the absence of explicit security headers and potential over-reliance on third-party tracking services. Opportunities exist to enhance accessibility and SEO further by adding ARIA attributes and structured data beyond Open Graph tags.
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.
