But the expanding mix of public and private clouds as well as software-as-a-service applications within the typical enterprise has also given rise to growing security concerns. Some 83% of enterprises surveyed by Flexera listed security as a challenge — ahead of concerns about managing cloud spend (listed by 82%) and governance (cited by 79%). “The challenge that multicloud presents to security teams continues to grow. The number of services that are being released, the new ways of interacting, the interconnecting of services and systems, all of that continues to advance and all of these add new complexities into the enterprise security model,” says Randy Armknecht, a managing director and the emerging technologies and global cloud practice leader at consulting firm Protiviti.
