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

华人街生活网 is a Chinese-language classified information platform targeting the Chinese community in the United States. It offers a wide range of services including job listings, housing rentals and sales, second-hand goods trading, store buying and selling, pet services, carpooling, and community news. The website positions itself as a leading platform for Chinese immigrants and residents in the US to find and post local classified ads. Technically, the site uses a custom CMS with common web technologies such as jQuery, Google Fonts, and Google Adsense for monetization. It is mobile-optimized and includes a QR code for easy mobile access. Security-wise, the site uses HTTPS and has a cookie consent mechanism, but lacks explicit security headers and publicly available security policies. The WHOIS data for the domain is missing or unavailable, which raises some concerns about domain registration legitimacy. Overall, the site is functional, content-rich, and serves a niche community effectively, but could improve its security posture and transparency.

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

9 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 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

    • 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

The website operates in the real estate and retail sectors, focusing on classified ads for the Chinese-speaking population in the US. Its business model is based on free posting of classified ads with monetization through Google Adsense advertising. The platform has a moderate size and consistent branding, with active content updates and community engagement. It maintains partnerships with other Chinese community websites. The lack of detailed company registration information and missing WHOIS data are notable gaps. The site targets a niche market segment, providing localized services and information, which supports its market position as a leading Chinese classifieds platform in the US.

Security posture

华人街生活网 demonstrates a basic to moderate security posture. HTTPS is enforced, and a cookie consent mechanism is implemented, indicating awareness of privacy compliance. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security robustness. No explicit security or incident response policies are publicly available, and no security.txt file or vulnerability disclosure program is found. The use of older JavaScript libraries like jQuery 1.11 may pose potential vulnerabilities if not regularly updated. The missing WHOIS data for the domain also introduces uncertainty regarding domain legitimacy. Overall, the site is functional but would benefit from enhanced security controls and transparency.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Regularly update all JavaScript libraries and dependencies to the latest secure versions to reduce risk of exploitation.
  3. Publish explicit security policies and incident response contact information to improve transparency and trust.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Verify and update WHOIS domain registration information to ensure domain legitimacy and improve business credibility.

Technical notes

Notes

The website uses a custom content management system with jQuery 1.11, Google Fonts, Google Adsense, and QRCode.js. It supports both PC and mobile devices with good mobile optimization. Performance is moderate with no major issues detected. SEO is basic with meta keywords and description present but no advanced structured data like JSON-LD or Open Graph tags detected. Accessibility features are minimal but basic navigation and structure are clear. Hosting provider details are not identified. The site uses Google Tag Manager and Google Analytics for tracking and marketing purposes. Overall, the technical infrastructure is functional but could be modernized and enhanced for better performance, security, and SEO.
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.
