What are best Mcafee solutions for a company with many nodes, connected to a centralized server which has many virtual machines. I heard the the e-policy orchestrator is a good choice, but isnt that supposed to be downloaded on the server and different products must be purchased for each node?
McAfee products are usually sold as a suite of individual products (you can also purchase them individually if you want). You choose which suite best matches your requirements and then purchase the number of clients seats that you require.
Most of the business/enterprise suites come with a license for ePO.
