Zero Trust Segmentation

Zero Trust has emerged as a foundational cybersecurity concept that can be applied to improve network, device, and user security. Prior to Zero Trust, organizations focused on securing their perimeters and assumed internal assets and internal communications were trusted and protected. But when an attacker breached an organization's perimeter defenses, they could move freely across networks and cause extensive damage.

With Zero Trust, security is never assumed—"never trust, always verify." No devices or connections are to be implicitly trusted. Instead of one-time access decisions, security is addressed dynamically, always adapting to observed changes in the environment. But how can organizations extend Zero Trust controls to unmanaged, IoT, IoMT, and OT devices?
