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

好家电维修网 is a Chinese national appliance repair service platform with over 10 years of experience, offering a wide range of repair services including air conditioners, refrigerators, washing machines, water heaters, gas stoves, and more. The website is well-structured and content-rich, targeting general consumers seeking reliable appliance repair services across multiple cities in China. The platform emphasizes quick response times, professional technicians, and after-sales warranty services. Technically, the site uses common JavaScript libraries such as jQuery and Swiper, with moderate performance and good mobile optimization. However, there is no evidence of advanced CMS or frameworks, and hosting details are not explicit. Security posture is moderate with some best practices like domain status protections but lacks DNSSEC and security headers. Privacy and cookie policies are absent, indicating compliance gaps. The WHOIS data shows a suspicious domain creation date in the future, which undermines trustworthiness and requires further verification. Overall, the site is functional and professional but would benefit from enhanced security and compliance measures.

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

11 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. 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

  3. 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';…

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 business operates as a service platform in the appliance repair sector, targeting a broad consumer base in China. It leverages a network of technicians and service points across many cities, positioning itself as a reliable and experienced provider with 10 years in the market. The business model focuses on connecting customers with repair services and providing informational content to support customer decisions. The presence of multiple partner domains in the friendly links section suggests an ecosystem of related services or affiliates. The company does not publicly disclose detailed corporate registration or certifications, which limits transparency. Growth potential exists given the broad service coverage and demand for appliance repair services in China.

Security posture

The website demonstrates a basic to moderate security posture. It uses HTTPS links but lacks visible security headers such as Content Security Policy or HSTS. DNSSEC is not enabled, which could expose DNS spoofing risks. The domain is protected against deletion and transfer, which is positive. No incident response or vulnerability disclosure information is provided, and no privacy or cookie policies are present, indicating compliance gaps with GDPR or similar regulations. The suspicious WHOIS domain creation date is a notable risk factor. Overall, the site should improve security configurations, implement privacy policies, and provide clear incident response contacts to enhance trust and compliance.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Implement standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve legal compliance and user trust.
  4. Add incident response and vulnerability disclosure information to demonstrate security maturity.
  5. Investigate and correct the domain WHOIS registration date anomaly to improve legitimacy and trust.

Technical notes

Notes

The website uses a traditional front-end stack with jQuery 2.2.4, Swiper, and Superslide for UI interactions and sliders. CSS and HTML5 are used for styling and structure. The site is mobile optimized and has good SEO meta tags but lacks advanced frameworks or CMS indicators. Performance is moderate with no explicit speed optimizations detected. No accessibility features beyond basic viewport meta tags are evident. The hosting provider is not explicitly identified beyond the registrar information. The site includes external scripts from Baidu for link submission but no analytics or tracking services are detected. Technical debt includes outdated jQuery version and lack of modern security headers.
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.
