Internal encryption ensures that all communication within a network, often referred to as east-west traffic, is cryptographically protected from sniffing and interception. In many industrial environments, data is sent in plain text once it passes the perimeter, allowing an attacker who has gained internal access to capture sensitive administrative credentials or process data. By using a managed internal certificate authority to encrypt all traffic between internal assets, you ensure that every session remains private and secure. See our blueprint for encrypting internal traffic.
