Risk levelLow

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

BITMAIN is a leading global manufacturer specializing in ASIC bitcoin mining hardware and blockchain-related solutions. The company targets both consumer and enterprise markets, offering a range of products designed for cryptocurrency mining and AI applications. Their market position is strong, supported by a comprehensive product catalog and global presence with offices in China, Hong Kong, Singapore, and the USA. The website reflects a mature digital infrastructure using modern JavaScript frameworks and analytics tools, indicating a good level of digital maturity. From a security perspective, the website enforces HTTPS and avoids exposing sensitive data, but lacks visible security headers and formal privacy or cookie policies, which are important for compliance and trust. The absence of WHOIS data reduces transparency and slightly impacts trustworthiness, though the business presence and content quality mitigate this concern. Overall, the security posture is solid but could be improved with enhanced compliance documentation and security best practices. The website is professionally designed with good content relevance and user experience, targeting a general audience interested in cryptocurrency mining hardware. No adult or questionable content is present, ensuring content safety. Strategic recommendations include adding privacy and cookie policies, implementing security headers, and publishing incident response and vulnerability disclosure information to enhance 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

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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

BITMAIN operates in the technology sector, focusing on cryptocurrency mining hardware and blockchain solutions. Their business model revolves around manufacturing and direct sales of ASIC miners and related products. The company enjoys a leading market position globally, supported by a broad product portfolio and international offices. Revenue streams likely include hardware sales and enterprise solutions. The target customers are cryptocurrency miners and blockchain enterprises. The company leverages partnerships and maintains active social media channels to engage customers. Growth indicators include recent product launches and participation in industry events. The website content and structure reflect a professional and consistent brand image, supporting business credibility.

Security posture

The website demonstrates a moderate to high security maturity level with enforced HTTPS and no visible exposure of sensitive data. However, the lack of security headers such as Content-Security-Policy and absence of privacy and cookie policies indicate compliance gaps. There is no evidence of incident response or vulnerability disclosure mechanisms publicly available, which could hinder timely security issue management. Data protection practices are not explicitly documented, and GDPR compliance indicators are missing. The use of third-party analytics and tracking scripts suggests moderate user tracking without clear privacy controls. Overall, the security culture appears functional but would benefit from formalized policies and transparency.

Recommendations

  1. Implement and publicly display comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish an incident response plan and vulnerability disclosure policy to facilitate security issue reporting and management.
  4. Enhance accessibility features to meet compliance standards and improve user experience for all users.
  5. Regularly audit and update third-party scripts and analytics tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built using modern web technologies, primarily Nuxt.js (a Vue.js framework), with extensive use of JavaScript and CSS for dynamic content and styling. It integrates multiple analytics services including Google Tag Manager, Baidu Analytics, and Alibaba Retcode for performance and user behavior tracking. The site demonstrates good mobile optimization and SEO practices with proper meta tags and structured data (JSON-LD). Performance is moderate, with preloading of critical assets and deferred script loading. No CMS is explicitly detected, suggesting a custom or framework-based solution. Hosting provider details are not evident from the content. Technical risks include the absence of security headers and incomplete privacy compliance documentation, which could affect regulatory adherence and security posture.
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.
