"Windows Event logs and device Syslogs are a real time synopsis of what is happening on a computer or network. EventLog Analyzer is an economical, functional and easy-to-utilize tool that allows me to know what is going on in the network by pushing alerts and reports, both in real time and scheduled. It is a premium software Intrusion Detection System application."
