Why Legacy Security Architectures Are Inadequate in a Multi-cloud World

Cloud services are a pillar of a digital transformation, but they have also become a thorn in the side of many security architects. As data and applications that were once behind the enterprise firewall began roaming free—on smartphones, between Internet-of-Things (IoT) devices, and in the cloud—the threat landscape expanded rapidly. Security architects scrambled to adjust their technologies, policies, and procedures. But just when they thought they had a handle on securing their cloud-connected enterprises, new business imperatives indicated that one cloud wasn’t enough. Modern enterprises operate in a multi-cloud world, where the threat landscape has reached a new level of complexity. Security teams are juggling a hodgepodge of policies, threat reports, and management tools. When each cloud operates in its own silo, the security architect has even more difficulty supporting the CISO or CIO with a coherent, defensible security posture.
