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

BNB Chain operates as a decentralized blockchain ecosystem focused on enabling Web3 decentralized applications (dApps) powered by the BNB token. The platform targets developers and users interested in blockchain technology, aiming to provide scalable infrastructure and tools for the next billion Web3 users. The website reflects a strong market position within the blockchain technology sector, emphasizing community-driven development and decentralization. Technically, the website is built using modern frameworks such as Next.js and Chakra UI, ensuring a responsive and performant user experience across devices. Integration of analytics tools like Google Tag Manager and Hotjar indicates a mature approach to user behavior analysis and optimization. However, the absence of explicit privacy and cookie policies suggests room for improvement in compliance and transparency. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data, but lacks visible security headers and formal security policies or incident response contacts. This indicates a moderate security posture with opportunities to enhance defenses and compliance. The domain WHOIS data is unavailable or privacy protected, which is common in blockchain projects but limits direct verification of registrant details. Overall, the website is professional, trustworthy, and technically sound, but should improve privacy disclosures and security headers to strengthen compliance and user trust.

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 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. 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"

  4. 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

BNB Chain is positioned as a leading blockchain ecosystem facilitating Web3 dApps, leveraging the BNB token as its native asset. Its business model revolves around providing blockchain infrastructure and developer tools to foster decentralized application growth. The target market includes blockchain developers, crypto enthusiasts, and enterprises exploring decentralized technologies. The platform benefits from a strong brand presence and community engagement, with active social media channels such as Twitter. Revenue streams likely include transaction fees, developer incentives, and ecosystem partnerships. The absence of detailed company registration or parent company information suggests it operates as an independent or community-driven entity. The use of privacy protection in domain registration aligns with industry norms for blockchain projects. Strategic partnerships and integrations with other blockchain services could further enhance its market reach and competitive advantage.

Security posture

The website demonstrates a baseline security posture with mandatory HTTPS encryption and no visible exposure of sensitive information in the HTML content. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces protection against common web attacks. No explicit security policies, incident response contacts, or vulnerability disclosure programs are published, indicating gaps in formal security governance and transparency. The presence of tracking scripts requires clear privacy disclosures to comply with GDPR and other regulations, which are currently missing. The domain's privacy-protected WHOIS registration is typical but limits external trust verification. Overall, the security maturity is moderate, with recommendations to implement security headers, publish security policies, and enhance privacy compliance to reduce risk and improve user confidence.

Recommendations

  1. Implement comprehensive privacy and cookie policies clearly accessible on the website to improve GDPR compliance and user trust.
  2. Add standard security headers (Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) to enhance protection against web vulnerabilities.
  3. Publish a security policy and incident response contact information to demonstrate commitment to security and facilitate vulnerability reporting.
  4. Review and disclose data retention policies related to analytics and tracking tools to align with privacy regulations.
  5. Consider domain WHOIS transparency or verified registrant information to strengthen legitimacy and trust signals.

Technical notes

Notes

The website leverages a modern technology stack including React-based Next.js framework and Chakra UI for styling, enabling a responsive and performant user experience. Integration with Google Tag Manager and Hotjar supports advanced analytics and user behavior tracking. The site is well-structured with proper meta tags and Open Graph data for SEO and social sharing. Performance appears optimized with deferred script loading and CSS preloading. Accessibility features are present but could be further enhanced with ARIA attributes and semantic HTML improvements. No CMS is explicitly detected, suggesting a custom or static site generation approach. Hosting provider details are not evident from the HTML content. Overall, the technical infrastructure is robust with minor opportunities for further optimization and security hardening.
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.
