11. Automate your processes
You need to figure out who ought to have access to what data in your newly merged company, and to do that, automated processes are key. "You must be able to create the roles, policies, and procedures necessary and have those rules put into effect without needing to go through one-by-one to change and manage permissions," says SailPoint's Cunningham.
Coming up with a unified set of security policies can be aided by automated tools as well. Michael Callahan, vice president at FireMon, points out that, as mergers invariably involve combining multiple vendors and legacy policies, "native management tools won't give the complete view necessary, so you should establish and enforce new best practices via a third-party management platform. A third-party tool with automated analysis will give you the picture you need to ensure secure access is maintained."
