Alert Logic® updates appliance software and makes product changes as needed throughout the year. When patches are available, we push them to appliances as soon as possible within our maintenance windows. Updates are designed for deployment without the need for on-site intervention by the customer. Customers will be notified via email prior to a release with information on the type and duration of maintenance window and again upon completion of the update.

The following maintenance windows may be used in support of Alert Logic products and services:
