• Design and deploy enterprise firewall rule sets across data centers, cloud platforms, and edge environments, including zone-based segmentation and micro segmentation policies to minimize attack surface.
• Conduct rule reviews, cleanup initiatives, and policy rationalization efforts to eliminate redundancy and reduce complexity.
• Develop and maintain workflows for rule provisioning, validation, and decommissioning using automation tools (e.g., Ansible, Terraform, Python) and integrate them with ITSM systems (e.g., ServiceNow) and CI/CD pipelines.
• Implement policy-as-code frameworks to standardize rule creation, change control, and compliance monitoring across on-prem and cloud environments.
• Design and manage firewall policies for AWS, Azure, and GCP, implement transit gateway/hub-and-spoke architectures, and align network security with cloud governance models.
• Provide tactical response for critical global incidents, codify lessons learned into reusable playbooks, and translate outcomes into enduring standards.
• Conduct network consulting engagements, produce reference architectures, define structured solutions (HLD, LLD, BoM, QA), emphasize Infrastructure-as-Code and observability, and map as-is to to-be states with prioritized remediation plans.
• Support the creation, refinement, and validation of firewall policies used for both production and lab deployments.
• Assist in reviewing and aligning firewall rulesets to updated segmentation strategies defined during design phases.
• Contribute to policy updates and validations required for migration of DMZ workloads to new fabrics.
• Support testing activities—including baseline traffic verification and resiliency checks—from a policy governance perspective.
• Assist in maintaining policy documentation, contributing to knowledge transfer, and supporting post-migration cleanup of legacy rules.
