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

The website '豆包' (doubao.com) is an AI-powered chat assistant platform offering a variety of productivity tools including writing, translation, programming help, and creative inspiration. The site targets a general audience interested in AI chat capabilities and content creation assistance. Technically, the site is built using modern web technologies such as React and integrates several ByteDance SDKs for performance monitoring and user identification. The infrastructure appears robust and optimized for fast loading and mobile responsiveness. Security-wise, the site enforces HTTPS and uses modern JavaScript SDKs, but lacks explicit security headers and visible privacy or cookie policies, which are areas for improvement. The absence of WHOIS data for the domain raises some concerns about domain registration transparency, although the website itself appears professional and legitimate. Overall, the site scores moderately well in content quality and technical implementation but scores lower in privacy compliance and business credibility due to missing policies and contact information.

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

10 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  3. 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

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

豆包 operates in the technology sector, focusing on AI-driven conversational tools and productivity enhancement. Its business model likely revolves around providing AI chat services possibly with freemium or subscription elements, targeting individual users and content creators. The platform leverages ByteDance's infrastructure and SDKs, indicating a strong partnership or internal affiliation. Market positioning appears as a niche AI assistant in the Chinese language market. The lack of explicit business registration or contact details limits full business intelligence assessment. No clear revenue streams or partnerships beyond technology providers are evident from the data.

Security posture

The website demonstrates a good baseline security posture with enforced HTTPS and use of reputable SDKs for monitoring and user tracking. However, it lacks visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which are recommended best practices. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and security transparency. The site would benefit from publishing clear security and privacy documentation and implementing additional HTTP security headers to enhance trust and protection.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to strengthen security posture.
  3. Provide clear contact information including support and incident response channels on the website.
  4. Regularly audit third-party scripts and SDKs for vulnerabilities and update them promptly.
  5. Increase domain registration transparency or provide justification for privacy protection to improve legitimacy perception.

Technical notes

Notes

The website uses a modern React-based frontend with extensive use of asynchronous JavaScript chunks for modular loading. It leverages ByteDance's CDN and SDKs for performance monitoring, user identification, and analytics. The site is optimized for mobile devices and uses preconnect and preload hints to improve resource loading. No CMS was detected, suggesting a custom or proprietary platform. Performance is fast with good SEO meta tags and Open Graph data. Accessibility is basic but could be improved with more ARIA attributes and semantic HTML. The technical stack is mature and well-maintained, but the lack of explicit security headers and privacy documentation are notable technical gaps.
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.
