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 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';…

  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

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

Tencent Cloud operates in the competitive cloud computing market, leveraging Tencent's extensive ecosystem and technology expertise. Its business model is service-oriented, providing scalable cloud infrastructure and platform services to a wide range of industries including gaming, finance, education, manufacturing, and government. The company benefits from strong brand recognition, a large developer community, and strategic partnerships. Revenue streams likely include pay-as-you-go cloud resources, subscription services, and enterprise solutions. The presence of numerous product categories and industry solutions indicates a diversified portfolio aimed at capturing broad market segments. Tencent Cloud's competitive advantage lies in its integration with Tencent's social and gaming platforms, advanced AI capabilities, and comprehensive security offerings.

Security posture

The website employs HTTPS with strong SSL configuration and integrates Tencent's Aegis security SDK for monitoring and incident detection. Asset retry mechanisms enhance reliability and availability of resources. However, the absence of explicit security headers such as Content-Security-Policy and lack of publicly available security policies or incident response contacts limit transparency. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Privacy compliance is basic, with no clear cookie consent mechanisms or GDPR-specific disclosures. Incident response and vulnerability disclosure processes are not evident. Overall, the security posture is solid but could be enhanced by publishing detailed security and privacy documentation and implementing additional HTTP security headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear consent mechanisms to improve privacy compliance.
  2. Add explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Provide a publicly accessible security policy and incident response contact information to enhance transparency and trust.
  4. Implement and publish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance visibility of contact information for business and security inquiries to improve user trust and support.

Technical notes

Notes

The website is built using modern web technologies including JavaScript frameworks (likely React), CSS3, and HTML5. It uses Tencent's proprietary CDN and caching infrastructure for fast content delivery. The integration of Aegis SDK indicates active security monitoring and performance tracking. The site is mobile-optimized with responsive design and good accessibility features. SEO is supported by proper meta tags and Open Graph data. Performance is fast with asset retry mechanisms to ensure resource availability. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting is on Tencent Cloud infrastructure, ensuring scalability and reliability. Opportunities exist to improve technical security headers and enhance privacy compliance mechanisms.
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.
