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

中国房产网 (lvdlsi.com) is a Chinese real estate information platform providing comprehensive listings for new homes, second-hand properties, rentals, and real estate news across multiple cities in China. The website targets consumers and investors interested in the Chinese housing market, offering a centralized portal for property transactions and market insights. The business model focuses on aggregating real estate listings and providing related informational content to facilitate property buying, selling, and renting. Technically, the website uses Destoon CMS, an older but specialized content management system popular in China, with jQuery libraries for frontend interactions. The site is served over HTTPS, includes mobile redirection to a mobile subdomain, and integrates Baidu's push script for SEO purposes. However, mobile optimization and accessibility are basic, and no advanced security headers or modern frameworks are detected. From a security perspective, the site has a basic SSL configuration and domain transfer protection but lacks DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options. There is no visible privacy or cookie consent mechanism, and no incident response or vulnerability disclosure information is provided. The domain is newly registered in June 2024, consistent with the website's recent content and launch. Overall, the website is functional and content-rich but has room for improvement in security posture, privacy compliance, and contact transparency. Strategic enhancements in these areas would improve user trust and regulatory 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

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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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';…

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 · found on this site
  • 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 positions itself as a comprehensive real estate portal in China, covering a wide range of property types and geographic locations through city-specific subdomains. Its competitive advantage lies in the breadth of listings and integrated real estate news and guides. Revenue streams likely include advertising, listing promotions, and possibly lead generation for real estate agents. The target customers are home buyers, sellers, renters, and real estate professionals. The presence of multiple city subdomains indicates a growth strategy focused on regional market penetration. Partnerships with various related service providers are indicated by the diverse external links. However, the lack of explicit company contact details and certifications may limit trust among more cautious users.

Security posture

The website demonstrates a basic security maturity level with HTTPS enabled and domain transfer protection. However, the absence of DNSSEC, security headers, and privacy compliance mechanisms indicates gaps in security best practices. No vulnerability disclosure or incident response information is available, which may hinder timely handling of security incidents. The lack of contact information for security or abuse reporting further reduces incident response readiness. While no critical vulnerabilities are evident from the content, the site would benefit from implementing modern security headers, DNSSEC, and clear privacy and security policies to enhance protection and compliance.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Add a comprehensive cookie policy and consent mechanism to comply with privacy regulations and improve user trust.
  4. Publish clear contact information including emails and phone numbers for customer support and security incident reporting.
  5. Improve mobile optimization and accessibility to enhance user experience across devices.

Technical notes

Notes

The website is built on Destoon CMS with jQuery libraries for frontend functionality. It uses standard HTML5 and CSS with some legacy support for older IE versions. The site includes Baidu push scripts for SEO but lacks modern JavaScript frameworks or advanced performance optimizations. Mobile support is provided via redirection to a mobile subdomain but is basic. The hosting provider is not explicitly identified beyond the registrar information. Performance is moderate with no evident advanced caching or CDN usage. The technical stack is functional but dated, suggesting opportunities for modernization to improve speed, security, and user experience.
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.
