Firewall & Perimeter Security consultants — engaged on fixed-scope contracts.
Design, deploy, audit and harden enterprise firewalls — Fortinet, Palo Alto, Cisco, Check Point, pfSense.
Typical firewall & perimeter security engagement
Engagements range from a single-site firewall replacement (HA pair, rule migration, cutover) to enterprise programmes adding internal segmentation, SD-WAN integration, and zero-trust micro-perimeters. Audits and rule-base rationalisation are common standalone fixed-scope pieces.

Firewall & Perimeter Security — frequently asked questions
Direct answers to the questions teams ask before engaging a firewall & perimeter security consultant on TalvexIT.
What does a firewall consultant do?
A firewall consultant designs and deploys perimeter and internal-segmentation firewalls (Fortinet, Palo Alto, Cisco ASA/FTD, Check Point, pfSense), reviews and rationalises rule bases, audits existing devices against industry best-practice, and runs migration projects between vendors or to next-generation platforms with full failover testing.
How long does a firewall refresh project take?
A single-site firewall refresh typically runs 2–4 weeks: 1 week of design and rule analysis, 1 week of staging and configuration, and 1–2 weeks of cutover, monitoring and post-cutover validation. Multi-site rollouts with SD-WAN integration usually run 4–10 weeks.
Can a TalvexIT firewall consultant work on Fortinet AND Palo Alto?
Most senior firewall consultants on the platform cover at least two of the major vendors (Fortinet, Palo Alto, Cisco, Check Point). When you publish a brief you can specify required vendor experience, and providers will only quote if they have hands-on production experience with that platform.
