Must-Have Requirements:


  • Solid understanding of networking fundamentals (TCP/IP, VLANs, routing, DNS, NAT).
  • Hands-on experience managing and auditing Firewall policies (e.g., Palo Alto, Fortinet, Cisco ASA).
  • Proficient with Proxy solutions (e.g., Squid, Zscaler, Bluecoat) including SSL inspection and access control.

  • Implement DDoS protection mechanisms using cloud or hybrid strategies.
  • Configure, monitor, and tune IDPS solutions for effective threat detection and response.
