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

Beosin is a blockchain security and compliance company founded in 2018, specializing in smart contract audits, VASP compliance, AML solutions, and cryptocurrency crime investigations. Positioned as a world-leading provider with a strong focus on Asian markets, Beosin offers services tailored to developers, law enforcement, and crypto businesses such as exchanges and wallets. The website reflects a professional and consistent brand image with clear service offerings and trust indicators including SOC 2 and ISO 27001 certifications. Technically, the site is built on modern frameworks like Nuxt.js and Vue.js, hosted with Cloudflare DNS and Amazon Registrar, and integrates analytics tools such as Google Tag Manager and Cloudflare Insights. Security posture is solid with HTTPS and domain status locks, though improvements are recommended in DNSSEC and security headers. Privacy compliance is weak due to missing privacy and cookie policies, and contact information is not explicitly provided. Overall, the site is trustworthy and well-positioned but would benefit from enhanced transparency and security documentation.

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

7 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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

Beosin operates in the blockchain security sector, targeting a niche market of crypto developers, law enforcement, and crypto businesses requiring compliance and security audits. Their competitive advantage lies in their formal verification technology and extensive on-chain data analysis, with over 45,000 vulnerabilities discovered and 4.7 billion wallet address labels. The business model focuses on service provision including audits, tracing, and compliance solutions. The company demonstrates growth and market presence through certifications and a broad customer base. Partnerships and social media presence support their ecosystem engagement. The absence of explicit contact details and privacy policies suggests areas for operational maturity improvement.

Security posture

Beosin exhibits a mature security posture with HTTPS enforced and domain registration protections in place. The presence of SOC 2 and ISO 27001 certifications indicates adherence to recognized security frameworks. However, the lack of DNSSEC and security headers reduces the overall security robustness. No vulnerability disclosures or incident response contacts are published, which could hinder rapid response to security events. The website does not expose sensitive data or use vulnerable libraries based on the analysis. Privacy compliance gaps exist, particularly regarding GDPR and cookie consent. Overall, the security posture is strong but can be enhanced by publishing explicit policies and improving DNS security.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with GDPR compliance and consent mechanisms.
  3. Add explicit contact information including security incident and general inquiry emails or phone numbers.
  4. Implement security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  5. Develop and publish a vulnerability disclosure and incident response policy to improve transparency and trust.

Technical notes

Notes

The website is built using modern JavaScript frameworks Nuxt.js and Vue.js, ensuring a responsive and performant user experience. Hosting and DNS are managed via reputable providers Amazon Registrar and Cloudflare, contributing to reliability and security. The site uses Google Tag Manager and Cloudflare Insights for analytics and monitoring. The design is professional with good mobile optimization and SEO practices. However, the absence of DNSSEC and security headers indicates technical debt in security hardening. No CMS detected, suggesting a custom or framework-based implementation. Overall, the technical infrastructure is solid with room for security 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.
