Native Cloud Firewalls Falling Short in a Multicloud World
Show notes
As enterprises expand across multiple cloud environments, on-premise data centers, and dynamic AI workloads, traditional perimeter defenses and siloed cloud-native tools are no longer enough to secure the modern network. In this episode, Ashish sits down with Murali Rathinasamy, Senior Director of Product at Cisco, to break down the next evolution of network security: the Hybrid Mesh Firewall. Murali explains why relying solely on cloud-native firewalls can create visibility gaps, and how unified policy orchestration allows security teams to manage enforcement points seamlessly. He shares a real-world case study of how Multicloud Defense is used to eliminate manual route table configurations and achieve zero-downtime, blue-green upgrades. The conversation also tackles micro-segmentation. Murali breaks down why segmentation initiatives usually stall in "analysis paralysis" and provides a practical, agentless roadmap to reduce your attack surface "one bite at a time".
