What purpose do policy checkpoints serve in the ProxySG?

In the context of the ProxySG, policy checkpoints play a crucial role in the processing of data transactions by evaluating the installed policy based on transaction information. This evaluation allows the ProxySG to determine whether to allow, block, or modify traffic according to the set policies.

During a transaction, when a request or response reaches a policy checkpoint, the system assesses the relevant data against predefined rules and criteria. This helps ensure that the behavior of the ProxySG aligns with organizational security and content management policies, enabling dynamic decision-making based on real-time data characteristics and user context.

This mechanism provides flexibility and adaptability in handling web traffic, as it ensures that each transaction is screened appropriately according to the latest policy definitions, which might vary based on factors like user roles, content types, or threat levels.

By performing these evaluations at policy checkpoints, ProxySG not only enhances security but also optimizes traffic management, ensuring compliance without sacrificing performance.
