Risk levelHigh

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

众优网 is a Chinese professional network marketing company specializing in SEO optimization, website construction, and comprehensive online marketing solutions targeting small and medium enterprises. The company emphasizes its proprietary SAAS intelligent website building system and extensive high-authority site resources to boost client search engine rankings and brand visibility. The website demonstrates a good level of content quality, clear navigation, and mobile optimization, supported by a moderate technical stack including jQuery, Slick Carousel, and WOW.js. However, the security posture is moderate with no DNSSEC, missing security headers, and lack of explicit HTTPS verification. Privacy compliance is poor due to absence of privacy and cookie policies. The WHOIS data shows inconsistencies with domain creation date in the future, conflicting with the business's claimed 9 years of experience, which raises trust concerns. Overall, the site is functional and professional but requires improvements in security and compliance to enhance trustworthiness.

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. 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 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';…

  4. 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

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 company positions itself as a specialized full-network marketing solution provider with a focus on integrated services including website building, SEO, SEM, and mobile marketing. It leverages proprietary technology and a large network of high-authority sites to deliver cost-effective and rapid results. The business model targets SMEs seeking sustainable online marketing ecosystems. The presence of numerous city-specific subdomains indicates a broad regional footprint in China. Trust signals include a national high-tech enterprise certification and a high customer satisfaction rate. However, the domain registration data inconsistency suggests potential issues with legitimacy or data accuracy that should be further investigated.

Security posture

The website currently lacks several key security best practices such as DNSSEC, security headers, and visible HTTPS enforcement. No incident response or security policy information is provided, and no dedicated security contact channels are found. The domain status flags provide some protection against unauthorized transfers or deletions. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No vulnerable libraries were explicitly detected, but the use of an outdated jQuery version may pose risks. Overall, the security maturity is moderate but requires enhancements to reduce risk and improve compliance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and trust.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Ensure HTTPS is properly configured and enforced site-wide with strong TLS settings.
  4. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  5. Add incident response and security contact information to improve transparency and readiness.

Technical notes

Notes

The website uses a combination of older and modern front-end technologies including jQuery 1.10.2, Slick Carousel, and WOW.js for animations. The site appears to be built on or related to the zblog CMS platform, as inferred from content references. Performance is moderate with autoplay sliders and marquee scripts. Mobile optimization is good with responsive CSS and viewport meta tags. SEO is supported by meta keywords and descriptions, and Baidu push scripts are included for indexing. Accessibility is basic with no ARIA landmarks or advanced features detected. Hosting provider details are not explicit but the registrar is eName Technology Co., Ltd. The domain lacks DNSSEC and security headers, indicating technical debt in security configuration.
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.
