Software-defined security (SDSec) is an architectural approach that allows security and compliance requirements to keep pace with the dynamics of software-defined data centers, private clouds, public IaaS, hybrid, and multi-cloud combinations. Based on five principles, SDSec provides security orchestration and automation in any infrastructure environment, at any scale. The result for security leaders is effective, efficient, and consistent security for applications and data – no matter what direction your cloud environment takes you.”]
