Events Per Second, or EPS, as it is commonly referred to in the world of network security, is a measurement that is used to convey how fast a network generates data from its security devices (firewalls, Intrusion Detection Systems, servers, routers, etc.), and/or how fast an SEM product can correlate data from those devices. A savvy buyer will match the EPS his network is generating to those that can be accommodated by the SEM tool that he is purchasing.

For the purpose of this article, we define the EPS that can be accommodated by an SEM tool more precisely as the number of security-related events a product can receive, normalize, analyze/correlate, and display or act on in the form of results within an acceptable time frame.
