Identity Governance and Web Access Management. As new employees join your organization, you face the conundrum of ensuring that they are given rights to all the systems and resources they need to do their work on the day they join the firm. Similarly, when a person changes positions within the firm, access that is no longer relevant must be revoked and access that is needed for their new position must be granted. For the situation of users leaving the firm or being terminated, it is even more imperative that permissions be addressed. Access to sensitive applications and data must be disabled/removed in a timely manner with traceability to avoid the consequences of a disgruntled user.
