• Support microsegmentation initiatives (e.g., Illumio) to enforce zero-trust network security principles across the enterprise.
• Evaluate the adequacy of firewalls, IDS/IPS, proxy gateways, and other network security devices; produce security recommendations and respond to security advisories and CVEs in a timely manner.
• Collaborate with Network Architecture, Cloud Networking, NOC, and IT operations teams to plan, develop, execute, and support infrastructure and network security-related projects.
• Provide Tier III technical support for network security incidents; assist with escalations to vendor TAC (e.g., Palo Alto Networks) and participate in the on-call rotation.
• Support disaster recovery exercises for Panorama and standalone firewall environments.
• Audit technical network security support tickets; document patterns, trends, and root cause analysis as they emerge.
• Contribute to operational documentation, SOPs, and knowledge transfer to enable NOC and junior engineers to support day-to-day security operations.
