Real-time access to log data can help IT admins to quickly identify problems and solve them. The example that Paglo CTO Chris Waters showed me was detecting a user who is trying to brute force their way through a login, by using a dictionary attack on the password. Through Paglo's collection and presentation of log data, along with great searching capabilities, it was easy to find the culprit and block the appropriate IP address.
Paglo's new log management application is free if you are already using Paglo on your network. It is also appears to be very easy to implement and works in harmony with Paglo's search indexer.
