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

51Tracking is a Chinese-based enterprise specializing in cross-border logistics API services, providing tracking solutions for over 1000 domestic and international couriers. The platform targets businesses requiring batch tracking and real-time logistics updates, positioning itself as a leading logistics API provider with a strong market presence evidenced by extensive customer testimonials and a high API success rate. Technically, the website employs a modern UIkit framework with jQuery and integrates Baidu Analytics and Udesk live chat for user engagement. The site is mobile-optimized and well-structured, offering a professional user experience. Security-wise, the site enforces HTTPS and claims ISO27001 certification, but lacks visible HTTP security headers and cookie consent mechanisms, which are areas for improvement. The absence of WHOIS data reduces domain transparency and slightly impacts trust. Overall, the site is professional and trustworthy but could enhance privacy compliance and security posture.

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

6 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

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 a B2B SaaS model focused on logistics tracking APIs, serving a medium-sized enterprise market primarily in China. It leverages partnerships with major logistics providers and cross-border e-commerce platforms, enhancing its competitive advantage. The business model relies on API usage fees and affiliate programs. The presence of extensive customer testimonials and partner logos indicates a mature ecosystem and strong market acceptance. Growth indicators include high cumulative query volumes and API request counts. Strategic observations suggest opportunities in expanding privacy compliance and incident response transparency to strengthen market trust.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and ISO27001 certification claimed. However, the lack of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options is a notable gap. Forms include client-side validation but lack visible CAPTCHA or advanced bot mitigation. No incident response or vulnerability disclosure information is provided, limiting transparency. The absence of cookie consent mechanisms may pose GDPR compliance risks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security maturity is good but can be improved by implementing recommended headers, privacy controls, and incident response disclosures.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to improve GDPR compliance and user privacy transparency.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  4. Provide clear incident response contact information to improve trust and readiness for security events.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a stable and widely adopted technology stack including jQuery 2.1.4 and UIkit for UI components. Integration with Baidu Analytics and Udesk live chat indicates a focus on user engagement and analytics. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Performance is moderate with no critical issues detected. The absence of a CMS suggests a custom or static site architecture. Technical debt appears low, but modernization opportunities include updating jQuery to a newer version and adding progressive web app features. The site is hosted on an unknown provider with no CDN explicitly detected. Overall, the technical infrastructure supports the business needs effectively with room for incremental improvements.
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.
