A packet sniffer shows you the information transmitted across your network. It allows you to monitor all transmissions, whether they be to and from the Internet, or occurring internally. Furthermore, you can use a packet sniffer as a security measure, guarding against informational leaks internally, or malicious attacks externally.

A single security breach can compromise your entire network, and cause millions of dollars' worth of damages. Because of this, it is highly imperative that you employ the use of a packet sniffer to protect your network. You can even customize alerts, so that in the event of a breach, you will be notified by email, pager, or phone.
