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

AUXSOL is a prominent Chinese solar inverter manufacturer and supplier, part of the AUX Group founded in 1986. The company specializes in on-grid and hybrid solar power inverters and energy storage solutions, targeting residential, commercial, and industrial sectors globally. The website demonstrates a professional digital presence with multimedia content, multilingual support, and detailed product and solution offerings. Technically, the site uses modern web technologies including Google Tag Manager and Baidu Analytics, and is mobile optimized with good SEO practices. Security posture is adequate with HTTPS and safe link handling, but lacks advanced security headers and explicit privacy policies. The absence of WHOIS registration data raises concerns about domain legitimacy, though the business information and certifications suggest a credible enterprise. Overall, the site is well-structured and trustworthy but would benefit from enhanced transparency on privacy and security policies.

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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 holds a strong market position as a leading solar inverter manufacturer in China, with a large workforce and significant revenue projections. Its business model focuses on manufacturing and supplying photovoltaic inverters and energy storage products, supported by technical and after-sales services. The website targets a global audience with multilingual options and emphasizes trust through certifications and membership in China's top 500 enterprises. The lack of visible direct contact emails or phone numbers may indicate a preference for contact via forms or regional offices. The company appears to have a solid partnership and product ecosystem but does not publicly disclose subsidiary or partner domains on the site.

Security posture

The website employs HTTPS and uses security-conscious link attributes to prevent tab-nabbing. However, it lacks visible security headers such as Content-Security-Policy or X-Frame-Options, which could improve protection against common web attacks. No incident response or vulnerability disclosure information is provided, which is a gap in security transparency. The site collects user data via contact forms but does not display explicit cookie consent banners or privacy policies, potentially impacting GDPR compliance. No known vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is moderate but could be improved with better policy disclosures and technical headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide explicit incident response and vulnerability disclosure contact information.
  4. Verify and publish WHOIS domain registration details to enhance domain legitimacy and trust.
  5. Enhance accessibility features to meet international standards and improve user experience.

Technical notes

Notes

The website is built using standard HTML5, CSS3, and JavaScript with jQuery. It integrates Google Tag Manager and Baidu Analytics for tracking and marketing purposes. The site is mobile responsive and supports multiple languages, indicating a mature internationalization strategy. Performance appears moderate with use of lazy loading for images and videos. No CMS or hosting provider information was detected. The site uses video backgrounds and interactive sliders to enhance user engagement. Technical debt is low, but improvements in accessibility and security headers are recommended to reduce risks and improve compliance.
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.
