Tiers are automatically adjusted depending on the hourly usage. As a result, customers
may be
billed in several different tiers in the same day. For example, Customer A has deployed
File
Storage Security to one of their Amazon S3 buckets. The incoming files traffic usually
stays
below 20 files per hour (free tier). But between 1pm to 3pm is their peak hours and
traffic can
go up to 150 files per hour (lower tier). In this case, they will be charged US$0.84
($0.42 x
2hour) per day.
File storage security billing calculations are based on the total scanned file count
per hour
per storage. If you can estimate the incoming file count per day, you can use the
chart below to
get an approximation of the maximum cost per day for a single storage.
For a more accurate estimate, you can find the total incoming file count per hour
using Amazon CloudTrail
(PutObject).

NoteFile Storage Security scans all incoming files. If you add the option to scan existing files,
additional costs will be applied.
