About Raunak Raj

I’m a Network Security Engineer with over 4 years of experience in setting up, managing, and securing networks in both enterprise and cloud environments.I work with Cisco switches (Catalyst 2960, 3850, 9300 and Nexus ), DNAC, Cisco Wireless (1832, 9120, 9166I), and Anchor WLC. I also handle Palo Alto firewalls (220, 440, 1400, 3410) using PAN-OS API, FortiGate firewalls(40F, 60F, 120F), and Juniper Mist Edge and SRX. On the cloud side, I manage AWS networking, creating VPCs, subnets, route tables, VPNs, and connecting cloud with on-prem setups.I take care of data center setups, including cabling, power planning, and device installation. I manage configuration hardening, perform vulnerability assessments (VA/PT), ensure compliance, and prepare for audits. For monitoring, I use tools like SolarWinds, Zabbix, SNMP, and Syslog to keep everything stable and secure.I focus on improving KPIs like faster issue resolution, clean deployments, and high uptime. I use Python and Ansible to automate tasks such as config pushes and reporting. I also coordinate with ISPs, hardware vendors, and client teams for link setups, escalations, and SLA-bound tasks.I handle network projects end-to-end—from physical setup and firewall provisioning to site-to-site VPNs, client coordination, and final delivery.What sets me apart is my ability to manage everything from cables to the cloud. I combine hands-on experience with security and automation to build networks that are stable, scalable, and reliable.
