Among SaaS-using companies, 57% have introduced SaaS management systems and 91% of them reported positive outcomes—including reduced workload, better cost control and enhanced security and governance. Security awareness is also growing among executives, with 61% expressing concern. Sharing real-life incident cases and hosting regular training sessions are among the top methods for raising awareness, making SaaS security a critical management issue.
