The crawler

The crawler is the name of the discovery and fingerprinting agent. It is selected by default when you install the Data Security Management Server or supplemental Data Security servers.

You can deploy additional crawlers in your network if you desire. When you set up a fingerprint task, you indicate which crawler should perform the scan. Websense recommends that you use the crawler that is located closest to the data you are scanning.

You can view the status of your crawlers in the TRITON - Data Security user interface. Go to Settings > Deployment > System Modules, select the crawler and click Edit.
