# Secure communication among components All components in the Cloudbrink solution always communicate over secure channels. Cloudbrink uses Mutual TLS (mTLS) based secure connections to ensure that both ends of the communication are always authenticated and authorized. Cloudbrink uses TLS 1.3 protocol only at all network segments which provides best available secure communication. Below are the communication channels that use mTLS 1.3. 1\) Cloudbrink Agent to the Cloudbrink SaaS 2\) Cloudbrink Agent to the Edge infrastructure 3\) Cloudbrink Edge infrastructure to the Cloudbrink SaaS 4\) Cloudbrink Connector to the Edge infrastructure 5\) Cloudbrink Connector to the Cloudbrink SaaS --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
