Security By Design’s Assist tool is used by contractors and end user organizations to document physical security infrastructure from initial surveys to final sign-off. Users of this app must contact Security By Design to set up an account with access to the appropriate data set. There is no charge to download, install or use this app, but access will not be provided unless approved by a current Security By Design client. The Assist app includes site and floor plans, where users can review physical security device location and type, answer questions, take relevant photos, and sign off security installations and surveys in the field. It allows users to temporarily download one or more sites with limited or no connectivity and synchronize when connectivity becomes available.
