How long does it take you to find out what happened on your SQL Server?

The free edition of Netwrix Auditor for SQL Server keeps you on top of what’s happening inside your database server by detecting logons and changes made to SQL Server objects and permissions, including server instances, roles, databases, tables, stored procedures and more. This free SQL tool sends daily reports detailing every change and logon made during the last 24 hours, including the before and after values for each modification.

Review SQL Server activity
Reports on successful and failed logons. Shows what SQL Server objects were added, modified or removed, with the current and past values.
Automate auditing
Collects and aggregates data about changes from multiple SQL servers and automatically sends daily reports to keep you informed.
Increase efficiency
Delivers meaningful data about changes and logons, eliminating the need to analyze mountains of native SQL Server logs.
Save your IT budget
Requires zero investment and will never expire or stop working when you need it.

Continuous monitoring of database activity is critical for data security and high availability of mission-critical applications and services. However, neither native tools nor most free SQL tools can efficiently monitor logons and configuration changes on SQL Server. The free edition of Netwrix Auditor for SQL Server eliminates the noise and enables you to stay on top of user activity on your SQL servers in a timely and convenient fashion.

Because databases are used to store valuable assets, they are normally hidden far behind firewalls. But even the most secure perimeter is not sufficient protection. The free edition of Netwrix Auditor for SQL Server reports on successful and failed logon attempts and configuration changes to harden database security. This free SQL reporting tool enables IT admins to review user activity in their database environments and detect potentially aberrant behavior to prevent data exfiltration.
