* Web: Actual size is based on web requests processed per day, which can be extrapolated from the peak requests per second in your network. If you are not able to determine these numbers, Forcepoint has found that the ratio of users to their peak number of web requests per second (as opposed to average number per second) is 10 to 1. This is an acceptable ratio to use for the purposes of estimating the number of users that this traffic represents in the average network. Note that this calculation is based on a standard curve distribution of traffic throughout the day, where the peak is mid-day and there is almost no traffic throughout the night. ** Email: Actual sizing is based on total email messages sent and received per day, including spam. Forcepoint has found that an estimate of 1 message per user per minute (including spam) is an acceptable estimate for the purposes of estimating the email volume generated for any given number of users.
