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

Shenzhen Suyite Technology Co., Ltd. operates the SellingExpress ERP platform, a professional Amazon ERP software solution targeting cross-border e-commerce sellers. Founded in 2009, the company leverages a core technical team from industry leaders such as Huawei, Amazon, Alibaba, and Kingdee. Their ERP software offers comprehensive features including PPC advertising management, FBA replenishment, sales reporting, listing monitoring, and customer service systems, positioning them as a mature player in the e-commerce technology sector. The company holds recognized certifications from Amazon, enhancing its market credibility. Technically, the website employs standard web technologies such as jQuery, CSS, and JavaScript, hosted on Alibaba Cloud infrastructure. The site is moderately performant with good mobile optimization and basic SEO and accessibility features. However, there is room for improvement in modern frameworks and enhanced technical SEO. From a security perspective, the site uses HTTPS but lacks DNSSEC and visible security headers, and does not publish privacy or cookie policies, indicating gaps in compliance and security best practices. No incident response or vulnerability disclosure information is provided. The WHOIS data is consistent and supports the legitimacy of the domain and business history. Overall, the website is professional and functional but would benefit from enhanced security measures, privacy compliance, and technical modernization to improve trust and reduce risk.

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

7 findings rated critical or high. Fix these first.

  1. 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: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP 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

  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"

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 targets Amazon sellers and cross-border e-commerce businesses with a B2B SaaS ERP solution. Their competitive advantage lies in deep industry experience, Amazon certifications, and a broad feature set tailored to refined Amazon store management. Revenue streams likely include subscription plans and service packages. The partnership ecosystem includes Amazon and related service providers, enhancing market reach. Growth indicators include 12 years of operation and multiple customer case studies. Strategic observations suggest focusing on compliance and security improvements to maintain competitive positioning.

Security posture

The current security maturity is moderate. HTTPS is implemented, but DNSSEC is not enabled, and no security headers are detected, which exposes the site to certain risks. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other regulations. No incident response or vulnerability disclosure mechanisms are evident, limiting readiness for security events. Data protection practices appear minimal, and no advanced security frameworks are referenced. The business impact of these gaps includes potential regulatory penalties and reduced customer trust.

Recommendations

  1. Enable DNSSEC and implement comprehensive security headers to harden domain and web security.
  2. Publish clear privacy and cookie policies with GDPR compliance to improve legal standing and user trust.
  3. Establish an incident response plan and provide contact channels for security issues to enhance preparedness.
  4. Conduct a security audit to identify and remediate potential vulnerabilities and improve overall posture.
  5. Modernize technical stack and improve SEO and accessibility to enhance user experience and market reach.

Technical notes

Notes

The website uses a traditional tech stack with jQuery and static CSS/JS files, hosted on Alibaba Cloud. Performance is moderate with some responsive design elements for mobile. The site lacks modern frameworks or CMS indications, which may limit scalability and maintainability. SEO is basic with minimal meta tags and no structured data. Accessibility is basic with no ARIA roles or landmarks detected. Technical risks include lack of DNSSEC and security headers, which could impact business continuity and data integrity.
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.
