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

亿数通 (Selmetrics) is a Chinese SaaS platform specializing in intelligent Amazon advertising management and comprehensive Amazon store operation management. The platform offers multi-store and multi-user advertising management, intelligent ad optimization, keyword analysis, profit accounting, supply chain management, and operational KPI monitoring. It targets Amazon sellers and cross-border e-commerce operators, positioning itself as a leading one-stop solution with over 100,000 sellers served. The website is well-structured, mobile-optimized, and uses modern web technologies such as Nuxt.js and Vue.js, with integration of Baidu analytics tools reflecting its Chinese market focus. Security posture is adequate with HTTPS enabled, but lacks some security headers and cookie consent mechanisms. The absence of WHOIS registration data is a concern for domain legitimacy, although the business content and certifications indicate a professional and trustworthy operation. Overall, the site demonstrates good business credibility and technical implementation but should improve transparency and security 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

7 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. 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

  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 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';…

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 e-commerce sector, providing SaaS tools for Amazon sellers to optimize advertising spend, manage profits, and streamline supply chain and operational metrics. Its competitive advantage lies in its integration with Amazon APIs, AI-driven keyword analysis, and multi-dimensional data analytics. The business model is subscription-based SaaS targeting medium-sized cross-border sellers. Partnerships with Amazon as a SPN service provider and advertising partner enhance credibility. The ecosystem includes ERP, payment, tax, and anti-detection browser partners, indicating a comprehensive service offering. Growth indicators include a large user base and significant managed ad spend. The company is based in China and focuses on the Chinese-speaking market.

Security posture

The website enforces HTTPS and avoids exposing sensitive data in its HTML content. However, it lacks important security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web attacks. No explicit security or incident response policies are published, and no contact channels for security issues are provided. Cookie consent mechanisms are absent, which may impact privacy compliance. The use of third-party analytics (Baidu) introduces moderate user tracking. Overall, the security maturity is moderate but could be improved by implementing best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web vulnerabilities.
  2. Add a cookie consent banner and detailed cookie policy to improve privacy compliance and user transparency.
  3. Publish a dedicated security policy and incident response contact information to build trust and readiness for security events.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Investigate and resolve the lack of WHOIS registration data to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website is built using modern JavaScript frameworks Nuxt.js and Vue.js, enabling server-side rendering and good SEO performance. It uses Bootstrap for responsive design, ensuring good mobile optimization. The site integrates Baidu analytics and marketing tools, indicating a focus on the Chinese market. Performance is moderate with preloading of scripts and styles. Accessibility features are basic but present. No CMS is detected, suggesting a custom or framework-based solution. Hosting provider details are not evident from the data. Technical risks include missing security headers and incomplete privacy compliance mechanisms, which could affect user trust and regulatory adherence.
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.
