+Description:
+The Google Chrome Content Analysis Connector provides an official mechanism
+allowing Data Loss Prevention (DLP) agents to more deeply integrate their
+services with Google Chrome.
+
+DLP agents are background processes on managed computers that allow enterprises
+to monitor locally running applications for data exfiltration events. They can
+allow/block these activities based on customer defined DLP policies.
