Key Responsibilities

Segmentation & Zero Trust Responsibilities (Juniper SRX Focus)

• Architect and implement network segmentation strategies using Juniper SRX firewalls across data center, campus, and cloud environments to limit lateral movement and enforce least-privilege access.
• Design and operationalize Zero Trust Architecture (ZTA) principles, integrating identity, application, and network-based policy enforcement using firewall controls.
• Collaborate with application owners to discover, validate, and map application dependencies to enable policy-driven segmentation via firewall rules and security zones.
• Define and enforce granular security policies using zone-based segmentation, VRFs, and SRX policy constructs across hybrid environments.
• Integrate segmentation with firewalls, SIEM, IAM, EDR/XDR, and cloud-native controls for unified policy enforcement.
• Lead adoption and standardization of Juniper SRX as the primary segmentation enforcement platform across enterprise environments.
• Develop segmentation governance models, policy lifecycle management, and compliance alignment (CIS/NIST/Zero Trust frameworks).
