The centralized system ensures user identification across all the networked enterprise resources and services. Users too benefit immensely, as they need a singular credential to access anything across the network enterprise.You can organize all users into groups based on IP addresses, user names or security group memberships in Microsoft Active Directory. Every group gets its own filtering exceptions and blocking rules. Authenticate your domain users using Kerberos, NTLM or Basic LDAP.
