For the safety and security of our clients, every security operative we employ must have a current and valid SIA license which is periodically checked against the SIA database of valid licenses. All Diligence Security employees are routinely licensed in the jurisdiction to which they are assigned, and we remove any operative from site as soon as their license is nearing expiration.
