Regulatory and Security Rules

To ensure compliance with global regulations and maintain the highest security standards, CM.com enforces rules that may restrict certain types of traffic. These rules are designed to protect your communications and align with local and international requirements.

Key Scenarios Where Traffic May Be Restricted

  1. TLS Version Requirements:
    • Traffic using TLS 1.2 or lower may be blocked for destinations that require TLS 1.3 for compliance or security reasons.
    • Unencrypted traffic (connections without TLS) may also be restricted to ensure secure communication.
  2. Destination-Specific Regulations:
    • Certain countries or regions enforce stricter telecom regulations that mandate the use of specific security protocols, such as TLS 1.3.
  3. Security-Driven Restrictions:
    • Traffic may be canceled if it does not meet CM.com's security standards, such as using outdated cryptographic methods or insecure connection protocols.
