The verification of groups and sites within the Horizon security system. In "Territory", groups and sites undergo a verification process both upon their creation and following any updates to their information. This verification is conducted utilizing the tools provided by the autonomous information security system known as "Horizon." From any individual group or site info card, users have the ability to follow a link that displays their verification status, including the date when the last verification was carried out. Moreover, by utilizing the verification history found in the public network operations monitor, it is possible to confirm the authenticity and integrity of the data at any given time, allowing for the tracking of changes as they occur.
