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

Tencent Real-Time Communication, Inc. operates the website trtc.io, offering a comprehensive real-time communication platform that enables developers and businesses to integrate video calls, voice calls, chat, conferencing, and live streaming into their applications. As a product under Tencent Holdings Limited, the company leverages its strong market position to provide scalable and feature-rich APIs and SDKs targeting a global developer audience. The website demonstrates a mature digital infrastructure using modern web technologies such as React and Next.js, with integrations for analytics and security monitoring. While the site is professionally designed and content-rich, there are areas for improvement in privacy compliance and security hardening, such as enabling DNSSEC and implementing cookie consent mechanisms. Overall, the security posture is solid with HTTPS enforced and domain protections in place, but explicit security policies and incident response information are lacking. The domain registration details align well with the corporate identity, supporting the legitimacy of the business.

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

4 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 is positioned as a leading technology provider in the real-time communication sector, leveraging Tencent's global brand and cloud infrastructure. The business model focuses on B2B SaaS offerings with APIs and SDKs for various communication needs, including niche areas like in-game voice chat and beauty AR. The company targets developers and enterprises requiring robust communication solutions, supported by a strong ecosystem of documentation, demos, and developer resources. The affiliate program and partnerships with Tencent Cloud enhance its market reach. The website content and social media presence reinforce its credibility and engagement with the developer community.

Security posture

The website employs HTTPS and reputable domain registration practices, including registrar-level domain status locks. However, DNSSEC is not enabled, which is a recommended security enhancement. No explicit security headers were detected in the provided data, and there is no public incident response or vulnerability disclosure policy. The use of Tencent Aegis and Sensors Analytics indicates active monitoring and analytics capabilities. The absence of cookie consent and detailed privacy notices may pose compliance risks under GDPR and similar regulations. Overall, the security maturity is moderate, with room for improvement in transparency and technical controls.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement a cookie consent mechanism to comply with privacy regulations and enhance user trust.
  3. Publish explicit security policies and incident response procedures to improve transparency and preparedness.
  4. Add security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website is built on a modern React/Next.js framework, indicating a server-side rendered React application optimized for SEO and performance. It uses Google Tag Manager for analytics and Tencent's own Aegis for security monitoring. The hosting is likely on Tencent Cloud, ensuring robust infrastructure support. Performance is moderate with good mobile optimization and basic accessibility features. The site lacks a CMS, suggesting a custom or static site generation approach. Technical debt appears low, but improvements in security headers and privacy compliance are needed to enhance the overall technical maturity.
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.
