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. 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 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';…

  2. 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

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

TrustAsia operates as an essential entity in the technology sector, focusing on digital certificates and network security solutions. Its business model revolves around providing SSL certificates and related security products, supported by cloud-based management platforms and security monitoring services. The company targets enterprise clients, particularly in sectors requiring high trust and compliance such as finance, healthcare, and IoT. The presence of multiple certifications and a broad product portfolio indicates a competitive advantage and strong market presence. The company maintains partnerships and showcases client cases, reinforcing its ecosystem. Revenue streams likely include certificate sales, subscription services for management platforms, and consulting/support services. Growth indicators include recent news on government electronic certification qualifications and participation in industry events. Strategic observations suggest a focus on innovation in PKI and national cryptography (国密) solutions.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple trust seals displayed, including WebTrust certifications. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, HSTS, and X-Frame-Options is a gap that could be addressed to enhance protection against common web attacks. Privacy and cookie policies are not explicitly presented, which may affect compliance with GDPR and other privacy regulations. Incident response and vulnerability disclosure mechanisms are not visible, limiting transparency in security management. Overall, the security culture appears strong given the nature of the business, but formalizing policies and enhancing header configurations would improve the security posture further.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear consent mechanisms to improve compliance and user trust.
  2. Add and enforce security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to strengthen web security.
  3. Establish and publicize incident response and vulnerability disclosure policies to enhance transparency and readiness.
  4. Investigate and resolve the missing WHOIS data issue to confirm domain registration legitimacy and improve trustworthiness.
  5. Continue to maintain and showcase trust indicators and certifications to reinforce market position and customer confidence.

Technical notes

Notes

The website uses a modern and robust technology stack including jQuery, CSS Vars Ponyfill for CSS variable support, Flexslider and Swiper for responsive sliders, and Slick Carousel for carousels. Analytics and tracking are implemented via Google Tag Manager, Hotjar, and Baidu Analytics, indicating a mature digital marketing and user behavior analysis setup. The site uses Bulma CSS framework inferred from class naming conventions, supporting responsive and mobile-friendly design. Performance is moderate with asynchronous loading of scripts and deferred analytics. Accessibility is basic but could be improved with more ARIA attributes and semantic HTML. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not available from the content. Overall, the technical implementation supports a professional and user-friendly experience with room for optimization in accessibility and security headers.
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.
