Security score

49/100

Risk levelHigh

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

The website signal-zh.org presents a Chinese localized version of the Signal secure messaging platform, emphasizing privacy, end-to-end encryption, and non-profit status. It offers downloads and information tailored for Chinese-speaking users, promoting Signal's core features such as encrypted messaging, calls, group chats, and stickers. The site is built on WordPress with modern plugins and hosted behind Cloudflare DNS services, providing a professional and accessible user experience. However, the domain is recently registered by a Hong Kong-based entity that does not match the official Signal Foundation, indicating this is likely a third-party localization rather than the official site. Security posture is good with HTTPS and no exposed vulnerabilities, but lacks published security policies and cookie consent mechanisms. Overall, the site is trustworthy for informational purposes but users should verify official sources for critical security assurances.

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. 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 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 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

The site targets Chinese-speaking users interested in secure communications, leveraging the well-known Signal brand. Its business model is non-profit, supported by donations, and it positions itself as an independent privacy-focused messaging service. The lack of direct contact information and mismatch in registrant details suggest it operates as a regional or community-driven site rather than a corporate entity. The presence of donation links and emphasis on no ads or tracking aligns with Signal's global positioning. The site maintains a clean, professional design with clear navigation and SEO optimization, supporting user engagement and growth within its niche audience.

Security posture

Security practices include enforced HTTPS, no visible sensitive data leaks, and use of secure open-source protocols. However, the absence of security headers and incident response contact details limits the overall security maturity. The site does not implement cookie consent despite using Google Analytics, which may raise privacy compliance concerns. No known vulnerabilities or malicious indicators were detected. The WHOIS data raises some trust concerns due to registrant mismatch and recent domain age, suggesting users should exercise caution and confirm authenticity when interacting with the site or downloading software.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, etc.) to enhance protection.
  2. Add a cookie consent banner to comply with privacy regulations and inform users of tracking.
  3. Publish clear terms of service, privacy, and security policies including incident response contacts.
  4. Clarify the relationship of the domain owner to the official Signal Foundation to improve trust.
  5. Enable DNSSEC to improve domain security and reduce spoofing risks.

Technical notes

Notes

The website uses a modern WordPress CMS with plugins for SEO (Rank Math) and AI content generation, supported by jQuery and Bulma CSS for UI. Hosting leverages Cloudflare DNS services, enhancing availability and security. Performance is moderate with good mobile optimization and accessibility features. The site uses Google Analytics for visitor tracking but lacks cookie consent. No forms collecting sensitive data were detected, reducing attack surface. The technical stack is well-maintained but could benefit from additional security hardening and compliance features.
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.
