The Data Loss Prevention (DLP) is a strategy for preventing individuals from accessing sensitive information who do not need it. It also ensures that employees do not send sensitive or critical information outside the corporate network. This is achievable thanks to the Message Content Protection (MCP) module.
To learn more about the DLP you can read the Data Loss Prevention approach explanation.
How it works
In Libraesva ESG you can define complex rules to analyze the content of messages and verify their compliance with corporate policies.
Each MCP rule has its score so the message will have, as is the case for antispam checks, a total score calculated by adding single rules scores that have been activated by MCP analysis, defined as MCP score.
When the MCP score reaches a configured and customizable threshold, one or more configured actions are performed by the appliance (e.g. Forward a copy of the message and Delete the message).
There are two configurable thresholds (MCP Score and High MCP Score). The goal of this two thresholds is to be 100% sure a message is a MCP message (we are sure if its score reaches the High MCP Score threshold).
For each thresholds different actions are customizable.
Note: the MCP score and the spam score are completely independent scores, having separate rules.
You can enable and customize this module behavior from the Message Content Protection Libraesva ESG page.
