Regulatory and Security Rules
Key Scenarios Where Traffic May Be Restricted
- 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.
- Destination-Specific Regulations:
- Certain countries or regions enforce stricter telecom regulations that mandate the use of specific security protocols, such as TLS 1.3.
- 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- Traffic may be canceled if it does not meet CM.com's security standards, such as using outdated cryptographic methods or insecure connection protocols.
