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

The website '火山写作' is an AI-powered writing assistant platform launched by ByteDance, targeting Chinese-speaking users. It offers integrated services such as content creation, text polishing, error correction, rewriting, and translation in both Chinese and English. The platform leverages modern web technologies including React and Axios, hosted likely on ByteDance's infrastructure, ensuring a moderate to good performance and mobile optimization. The site is professionally designed with consistent branding and relevant content focused on AI writing assistance. From a security perspective, the website enforces HTTPS and uses modern JavaScript libraries, but lacks DNSSEC and important security headers. There is no visible security or incident response policy, and no contact information is provided, which limits transparency. Privacy compliance is partial, with privacy and terms pages present but no cookie consent mechanism. Analytics and tracking are implemented via ByteDance's internal tools, with moderate user tracking levels. Overall, the domain registration is consistent with the business claims, registered through a reputable Chinese registrar with no privacy protection, and the domain age aligns with the service launch. No suspicious patterns or blocking mechanisms were detected. The website is safe for general audiences with no adult or questionable content. The AI score reflects good content and technical implementation but is reduced by privacy and security gaps. Strategic recommendations include enabling DNSSEC, implementing security headers, adding explicit cookie consent and privacy compliance mechanisms, publishing security and incident response policies, and providing clear contact 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

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"

    • 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 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

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

The platform operates under ByteDance, a major technology company, positioning itself strongly in the AI writing assistance market. Its business model is SaaS-based, targeting individual and professional users needing AI-enhanced writing tools. The service leverages ByteDance's AI capabilities and infrastructure, providing competitive advantages in technology and market reach. Revenue streams likely include subscription or usage-based fees. The absence of visible partnerships or subsidiaries suggests a focused product offering. Growth potential is supported by the increasing demand for AI writing tools in Chinese and English markets.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of modern libraries. However, the lack of DNSSEC, security headers, and public security policies indicates gaps in defense-in-depth and transparency. No incident response contacts or vulnerability disclosure mechanisms are present, which could delay response to security events. Privacy compliance is partial, lacking cookie consent mechanisms and GDPR indicators. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate but requires improvements to meet higher compliance and trust standards.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner/mechanism to comply with privacy regulations and improve user transparency.
  4. Publish explicit security policies and incident response contact information to improve trust and readiness.
  5. Provide clear contact information including support emails or phone numbers to enhance business credibility.

Technical notes

Notes

The website uses a modern React-based frontend with libraries like Axios and Lodash, ensuring modular and maintainable code. It loads fonts from Google Fonts and uses ByteDance's CDN infrastructure for static assets, indicating a robust hosting environment. Performance is moderate with deferred script loading and CSS chunking. Mobile optimization is good, but accessibility features are basic and could be improved. SEO is supported by proper meta tags and Open Graph data. No CMS was detected, suggesting a custom-built platform. Technical risks include missing DNSSEC and lack of security headers, which should be addressed to reduce attack surface.
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.
