Cybersecurity Mesh: Distributed Security Architecture for Modern Enterprises
As organizations become more distributed, cybersecurity mesh architectures provide flexible, scalable security that follows digital assets wherever they go.
Traditional perimeter-based security models are inadequate for today’s distributed, cloud-first organizations. Cybersecurity mesh architectures provide a more flexible, composable approach to security that can protect digital assets regardless of their location, enabling secure operations across hybrid and multi-cloud environments.
