Account's Bandwidth

Created at:

Incapsula bills for bandwidth usage according to the 95th percentile of the amount of bandwidth used in that month. Each plan has its own monthly bandwidth allocation, as listed below:

Plan Bandwidth
Free 5Mbps
Pro 5Mbps
Business 5Mbps
Enterprise 20Mbps+

Every 5 minutes, our systems measure the average rate of data (in bits per second) which is transferred between your website visitors and all of your sites on the Incapsula network, in both directions (visitor<>Incapsula). 

We drop the top 5% of our measurements - i.e. when your bandwidth usage was at its highest peak - and the remainder is the 95th percentile that will be considered as your bandwidth usage.

Note that:

  • Incapsula does not charge for data transferred between Incapsula's proxy and your servers, only traffic between visitors and the Incapsula proxy.
  • Blocked traffic is not calculated as part of the 95% (blocked traffic includes blacklisted traffic, L3/4 DDoS traffic, L7 DDoS traffic, bad bots, security rules and others)
  • In case the total bandwidth of your account exceeded the bandwidth allocated to your plan, you will be asked to upgrade to a plan that better suits your bandwidth usage. 


The 95 percentile is presented in the Traffic Dashboard:
