NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

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

9 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 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';…

  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

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 platform operates as an essential hub for cross-border e-commerce sellers, providing news, tools, and service provider listings that facilitate seller operations and growth. Its business model revolves around content provision, tool integration, and service marketplace facilitation. The domain age and WHOIS data confirm a long-standing presence, enhancing trust. The site maintains partnerships with various service providers and uses a CDN for static content delivery. Its target audience is primarily Chinese cross-border e-commerce sellers, with a medium-sized operational scale. The platform's extensive content and service offerings position it competitively within the e-commerce support ecosystem.

Security posture

The website enforces HTTPS and uses axios interceptors for error handling, indicating a baseline security awareness. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, and does not publicly disclose security policies or incident response procedures. No vulnerability disclosures or security.txt files are present. The absence of cookie consent mechanisms also indicates partial privacy compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could benefit from enhanced header configurations and transparency in security policies.

Recommendations

  1. Enable DNSSEC to improve domain name security and prevent DNS spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Publish explicit security and incident response policies to enhance transparency and trust.
  4. Add a cookie consent banner and detailed cookie policy to comply with privacy regulations.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses a modern and robust technology stack centered around Vue.js for reactive UI, Axios for API communication, and Bootstrap for responsive design. Static assets are served via a CDN, improving load times. The site is mobile optimized and has good SEO metadata including Open Graph tags. However, accessibility features appear basic and could be improved. Performance is moderate, with potential for optimization in asset loading and caching. The site does not rely on a known CMS, indicating a custom-built solution which may require dedicated maintenance. Overall, the technical infrastructure supports the business needs effectively but could be enhanced with additional accessibility and performance tuning.
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.
