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

广州傲群新材料有限公司 operates a professional industrial brush manufacturing website offering custom brush products including polishing brushes, industrial brush rollers, cleaning brushes, and brush strips. The company targets industrial manufacturers and large enterprises, positioning itself as a trusted supplier to major corporations including several Fortune 500 companies. The website is content-rich, primarily in Chinese, and showcases certifications such as ISO13485, ISO9001, FDA, RoHS, and SVHC compliance, along with multiple patents, indicating a strong business credibility and industry presence. Technically, the website uses common JavaScript libraries like jQuery and WOW.js, and integrates Baidu and Google Analytics for user tracking. Mobile optimization is basic with a redirect to a mobile subdomain. Security posture is moderate with HTTPS implied but lacks explicit security headers and privacy policies. WHOIS data is unavailable, raising concerns about domain registration legitimacy, though the website content suggests an active business. Overall, the site is professional but would benefit from enhanced privacy compliance and security best practices.

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. 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';…

  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

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.

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 operates in the manufacturing sector with a focus on industrial brushes serving sectors such as transportation, energy, and technology. Its business model is B2B, providing custom manufacturing solutions and supply to large enterprises and industry leaders. The website indicates strong market positioning through partnerships with major companies and multiple certifications. The presence of patents and quality certifications supports a competitive advantage. The company appears large in size with a well-established production capacity. The website content and partner listings suggest a robust partnership ecosystem. However, the lack of WHOIS transparency and privacy policies may impact trust for some stakeholders.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and no visible sensitive data exposure. However, it lacks critical security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which are important for mitigating common web attacks. No vulnerability disclosure or incident response information is provided, and no security policy is visible. The use of third-party analytics and tracking scripts without clear privacy disclosures indicates compliance gaps, particularly with GDPR. The absence of a security.txt file or vulnerability reporting channel reduces incident response readiness. Overall, the security posture is functional but requires improvements to align with best practices and regulatory requirements.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web vulnerabilities.
  2. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms to improve GDPR and global privacy compliance.
  3. Establish a security.txt file and a clear vulnerability disclosure process to improve incident response and transparency.
  4. Enhance mobile optimization and accessibility features to improve user experience across devices and for users with disabilities.
  5. Verify and update domain WHOIS registration information to ensure transparency and trustworthiness.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 1.9.1 and WOW.js for animations, along with Baidu and Google Analytics for tracking. The HTML structure is well-formed with meta tags for SEO and social verification. Mobile redirection is implemented but mobile optimization is basic. No modern frameworks or CMS are detected, indicating a custom or legacy platform. Performance is moderate with no explicit indicators of optimization or CDN usage. Accessibility features are minimal. The site lacks advanced security headers and privacy compliance mechanisms. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security controls.
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.
