Security controls can be customized with in-line monitoring and blocking on some databases and monitoring only on other databases. The Database Firewall can be deployed in-line, out-of-band, or in proxy mode to work with the available network configurations. For monitoring remote servers, the Audit Vault Agent on the database server can forward the network traffic to the Database Firewall. Delivered as a soft appliance, a single Audit Vault Server can consolidate audit logs and firewall events from thousands of databases. Both Audit Vault Server and the Database Firewall can be configured in a HA mode for fault tolerance.
