Paralysis by Analysis is a humoristic phrase used to indicate the situation wherein no decision at all can be made due to devoting disproportionate effort to the analysis phase of a decision.

Advanced Security Management lets you set up activity policies that can track specific activities. With out-of-the-box templates, IT can easily create policies that flag when someone is downloading an unusually large amount of data, has multiple failed sign-in attempts or signs in from a risky IP address.
