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

国家建造师网 is a Chinese online educational platform specializing in providing comprehensive information and resources related to construction professional certification exams such as the secondary construction engineer exam, cost engineer, urban planner, and other related certifications. The website offers exam registration details, schedules, past exam questions, and score inquiries, targeting construction professionals and exam candidates in China. The platform positions itself as a reputable and specialized service provider in the construction education sector with a medium-sized operational scale and a recent founding date in 2024. Technically, the website employs standard web technologies including jQuery and Bootstrap, ensuring a responsive and user-friendly interface optimized for mobile devices. The site structure is clear with well-organized navigation and relevant meta tags for SEO. However, there is no evidence of advanced CMS usage or modern frameworks beyond Bootstrap. Performance is moderate with room for improvement in accessibility and security configurations. From a security perspective, the domain is registered transparently with no privacy protection, which aligns with the business nature. The domain status clientTransferProhibited is a positive indicator against unauthorized transfers. However, the absence of DNSSEC, security HTTP headers, and privacy/cookie policies indicates gaps in security best practices and regulatory compliance. No WAF or blocking mechanisms are detected, and the site content is fully accessible. Overall, the website is a functional and content-rich educational resource with moderate technical maturity and business credibility. Key risks include lack of privacy compliance documentation and limited security hardening. Strategic improvements in these areas would enhance trust and regulatory adherence.

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention gkweb3.com, from OffSeq Breach.

No leaked records found

Breach holds no records for gkweb3.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 platform serves a niche market of construction certification candidates in China, providing timely and relevant exam-related content. Its business model revolves around content provision and possibly advertising or affiliate partnerships with related educational services. The site maintains partnerships with various related domains, indicating a networked ecosystem. Growth potential exists given the specialized focus and consistent content updates. However, the new domain age suggests the business is in early stages of market penetration. The absence of direct contact emails or social media presence may limit customer engagement channels.

Security posture

The security posture is basic with some positive domain registration controls but lacks critical security headers and DNSSEC. No incident response or security policy information is available, and no vulnerability disclosure or security.txt files are found. The site uses HTTPS (implied by URL) but SSL configuration details are unknown. The lack of privacy and cookie policies is a compliance concern. Overall, the security maturity is low to moderate, with recommendations to implement standard security headers, enable DNSSEC, and publish privacy and cookie policies to improve compliance and trust.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to address compliance gaps.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add standard security HTTP headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Establish an incident response contact channel and consider publishing a security.txt file for vulnerability disclosure.
  5. Enhance accessibility features and conduct performance optimization to improve user experience and SEO.

Technical notes

Notes

The website uses a traditional web stack with jQuery and Bootstrap for frontend UI and interactivity. The HTML is well-structured with responsive design elements and meta tags for SEO. External scripts include Baidu push for indexing. No modern JavaScript frameworks or CMS platforms are detected. Hosting and registrar information is limited but domain registration is recent and consistent. Performance is moderate with basic mobile optimization. There is no evidence of advanced technical debt but security and privacy implementations are minimal, representing technical risks for compliance and trust.
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.
