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

中国房源网 is a Chinese real estate platform specializing in new, second-hand, and rental property listings across multiple cities in China. The website provides a comprehensive range of real estate services including property listings, market news, and educational content aimed at buyers, sellers, and renters. The platform targets the Chinese real estate market with a focus on convenience and professional brokerage services. Technically, the site uses jQuery libraries and appears to be built on the Destoon CMS platform, with moderate performance and basic mobile optimization. Security posture is moderate with HTTPS enabled but lacking advanced security headers and DNSSEC. Privacy compliance is limited with no cookie policy or consent mechanism detected. WHOIS data raises concerns due to a future domain creation date and registrant information pointing to a registrar company rather than the business operator. Overall, the site is functional and content-rich but could improve in security and compliance areas.

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 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.

Dark web exposure

Add-on

Leaked records that mention zzmkz.com, from OffSeq Breach.

No leaked records found

Breach holds no records for zzmkz.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

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 sector, focusing on property listings and brokerage services in China. It serves a medium-sized audience with a business model based on online listings and possibly advertising or brokerage commissions. The platform maintains partnerships with various related websites as indicated by friendly links. The lack of explicit contact information and privacy policies may impact user trust. The domain registration details suggest potential inconsistencies that warrant further verification. The site’s content is regularly updated with news and property listings, indicating active business operations.

Security posture

The website employs HTTPS and has domain status protections to prevent unauthorized transfers or deletions. However, it lacks DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options, which are important for mitigating common web attacks. No incident response or security policy information is published, and no vulnerability disclosure or security.txt file is found. The absence of cookie consent mechanisms also indicates limited privacy compliance. These gaps present moderate security risks that should be addressed to enhance trust and compliance.

Recommendations

  1. Enable DNSSEC to secure DNS queries and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear privacy policy and cookie consent mechanism to comply with privacy regulations.
  4. Provide explicit contact information including company emails and phone numbers to improve business credibility.
  5. Establish and publish a security policy and incident response contact to enhance security posture and user trust.

Technical notes

Notes

The website uses a legacy and a newer version of jQuery, indicating partial modernization. The presence of Destoon CMS suggests a custom or niche platform for real estate. The site loads CSS and JavaScript resources from its own domain, with some external scripts from Baidu for push notifications. Mobile optimization is basic with a mobile redirect meta tag and a mobile site URL. SEO is supported by meta keywords and description tags in Chinese. Performance is moderate with no explicit indicators of optimization or CDN usage. Accessibility features are minimal but basic navigation and structure are present.
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.
