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

Tencent Real-Time Communication, Inc. (Tencent RTC) is a technology enterprise specializing in providing real-time communication APIs and SDKs for video calls, voice calls, chat, conferencing, live streaming, and AI-powered conversational services. As a subsidiary or product line under Tencent Holdings Limited, it leverages Tencent's global technology infrastructure and market presence to offer robust, scalable communication solutions targeting developers and businesses worldwide. The platform supports multiple languages and offers comprehensive developer resources, demos, and pricing plans to facilitate adoption. Technically, the website is built on modern web technologies including Next.js and React, with integrations for analytics and security monitoring such as Google Tag Manager and Tencent Aegis. The site is well-optimized for performance, mobile responsiveness, and SEO, reflecting a mature digital infrastructure. Hosting is likely provided by Tencent Cloud, ensuring reliable uptime and scalability. From a security perspective, the site enforces HTTPS, uses registrar domain locking statuses, and includes security monitoring scripts. However, it lacks DNSSEC and publicly available security policies or incident response contacts, which are areas for improvement. Privacy compliance is partially addressed with a comprehensive privacy policy and GDPR indicators, but cookie consent mechanisms are missing. Overall, Tencent RTC presents a high level of business credibility and technical sophistication with a strong market position. The risk profile is low, with recommendations to enhance security transparency and privacy compliance to further strengthen trust and regulatory adherence.

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

3 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 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 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

Tencent RTC operates in the competitive real-time communication technology sector, leveraging Tencent's brand and infrastructure to deliver APIs and SDKs for interactive audio, video, chat, and AI conversational services. Its business model is B2B SaaS, targeting developers and enterprises needing embedded communication features. The company offers a broad product suite including call, conference, chat, live streaming, in-game voice chat, and beauty AR SDKs, positioning itself as a comprehensive RTC provider. The affiliate program and active social media presence indicate a growth-oriented marketing strategy. The domain registration and corporate information align with Tencent Holdings Limited, reinforcing legitimacy and market trust. The platform's multilingual support and extensive developer resources suggest a global target audience and a focus on developer experience.

Security posture

The website demonstrates a good security posture with HTTPS enforced and domain registrar locks preventing unauthorized transfers or deletions. The inclusion of Tencent Aegis security monitoring scripts indicates active threat detection. However, the absence of DNSSEC reduces DNS security robustness. No explicit security policies or incident response contacts are published, which limits transparency and preparedness communication. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is partial, with a privacy policy present but lacking cookie consent mechanisms. Overall, the security maturity is solid but could be enhanced by publishing security policies, enabling DNSSEC, and implementing cookie consent to meet best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a dedicated security policy page detailing security practices and incident response procedures.
  3. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  5. Publish terms of service to clarify legal usage and liability for users.

Notes

The website is built using Next.js, a React framework optimized for server-side rendering and static site generation, contributing to fast load times and SEO friendliness. It uses Tencent's TDesign UI components for consistent styling and user experience. Analytics are integrated via Google Tag Manager, and security monitoring is provided by Tencent Aegis. The site is mobile-optimized and accessible, with proper meta tags and structured data (JSON-LD) for SEO and social media integration.

The technical stack is modern and well-implemented, supporting scalability and maintainability. Opportunities exist to improve security configurations and privacy compliance features.
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.
