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

Sigenergy Technology Co., Ltd. is a prominent company specializing in home battery storage and energy solutions for residential and commercial applications. The company positions itself as a leader in the energy storage sector, offering a broad portfolio of products including home battery systems, commercial inverters, energy gateways, and cloud-based energy management platforms. Their website demonstrates a strong market presence with multi-language support and active engagement through social media and news updates. Technically, the website employs modern JavaScript libraries and frameworks such as jQuery, GSAP, and Swiper, ensuring a smooth and interactive user experience. The site is mobile-optimized and features comprehensive navigation and content relevant to its target audience of homeowners, businesses, installers, and partners. Security-wise, the site enforces HTTPS and includes cookie consent mechanisms, though it lacks explicit security headers and published 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

2 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Sigenergy operates in the energy sector, focusing on renewable energy storage solutions for both residential and commercial markets. Their business model includes direct product sales, installer and partner programs, and cloud-based energy management services. The company has established itself as a market leader, notably recognized as the top battery brand in Australia by market share. Their ecosystem includes partnerships with distributors and installers, supported by certification and training programs. The website content and linked domains indicate a well-developed partnership network and a commitment to innovation, including AI-driven energy solutions. Growth indicators include recent news about manufacturing expansion and strategic partnerships. The company targets environmentally conscious consumers and businesses seeking sustainable energy independence.

Security posture

The website demonstrates a good security posture with mandatory HTTPS encryption and a cookie consent mechanism compliant with GDPR. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could be addressed to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not publish a dedicated security policy or incident response contact information, which limits transparency and preparedness perception. The use of third-party scripts like Google Tag Manager and YouTube API is standard but requires ongoing monitoring for vulnerabilities. Overall, the security maturity is moderate with room for improvement in policy disclosure and header implementation.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response procedures on the website to improve transparency and trust.
  3. Regularly audit and update third-party libraries and scripts to prevent vulnerabilities.
  4. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.
  5. Consider adding a vulnerability disclosure program and a security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses a modern and interactive front-end technology stack including jQuery, GSAP for animations, Swiper for sliders, and Locomotive Scroll for smooth scrolling effects. Google Tag Manager and Google Analytics are integrated for tracking and analytics. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with some heavy animations and large images that could be optimized further. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site includes multi-language support with hreflang tags and language selection scripts, enhancing global reach. Overall, the technical infrastructure supports a professional and engaging user experience but could benefit from performance optimizations and enhanced accessibility.
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.
