Enterprise networks are changing faster than traditional security architectures were designed to accommodate. Applications are moving to the cloud, employees are accessing systems from different locations and devices, and organizations are increasingly operating across hybrid and multi-cloud environments. These shifts are reducing the effectiveness of security models built around fixed corporate perimeters.
