LANGuardian monitors and records every access to your SQL Server databases,
helping you to protect sensitive business data, secure your database
infrastructure, detect fraudulent activity, and more easily meet your audit and
Because LANGuardian generates its activity data from SQL Server network
traffic, it has zero performance impact and it gives you a single point of
access to the activity data for your entire database environment. This is a
significant improvement on the native logging and auditing utilities that come
with SQL Server. The native utilities create log files on a per-server basis,
making it difficult and time-consuming to monitor the log files for an
environment with many SQL Server instances. Database performance is also
affected when native logging is enabled.
SQL Server Database Monitor helps you to lower IT costs and increase operational
efficiency by automating many database auditing and security tasks. You can
configure it to automatically issue e-mail alerts or SNMP traps in real time
when security policy violations occur. This feature is commonly used to notify
an administrator when a SQL
Server instance is accessed by a specified client.
Knowing where data is located in your organisation is critically important
for risk management and compliance.
LANGUardian helps you discover where important data is stored. You can create
reports that list all databases on your network, see which users are accessing
them, and what SQL statements they are applying. If a developer makes a copy of
your customer database for testing purposes, or a new application begins
interacting with your HR database, LANGuardian will bring it to your attention.
It will also notify you as new
databases appear on the network.
How it works
LANGuardian uses network traffic capture and analysis to generate an audit trail of all SQL Server database activity. It records details of the user and application that accessed the database, the SQL statement used, and the database to which it applied. It works by monitoring the network traffic that passes through the SPAN or NetFlow port on your core network switch, using deep packet inspection (DPI) techniques to analyze the traffic and identify the SQL statements that users and applications are transmitting over network.
