*Price difference between SAFE for Evidence Management and SAFE for Ediscovery reflects discounted pricing for the public sector. CAL= Concurrent Access Licence. The number of CAL purchased equals the number of “users” that can be concurrently logged into the software at the same moment in time. You do not need a CAL for every “user” in your department. Simply stated, when a person logs into the system, a license is utilized. As soon as that person logs out of the software, the license becomes available for another user. Therefore, the number of CALs purchased will equal the maximum number of concurrent users that can be working in the software at once.
