Network Specialist Hybrid

Role Overview

As a Network and Firewall Specialist, you will deliver a major enterprise programme focused on reducing cyber risk through firewall remediation, Zero Trust segmentation, and least‑privilege access across the organisation. You will lead the identification and remediation of firewall and segmentation risks from audits and security assessments, including overly permissive rules, lateral movement exposure, DMZ weaknesses, and inadequate outbound controls. The role is responsible for designing and implementing a secure segmentation model across user, server, management, Tier‑0, and DMZ zones, enforcing controlled inter‑zone communication and eliminating unnecessary east‑west traffic.

You will own firewall policy governance, ensuring rules are business‑justified, least‑privilege, fully logged, and regularly reviewed, including removal of “any/any” access and reduction of Active Directory exposure. Working with Infrastructure, Cyber Security, and third parties, you will coordinate remediation delivery and ensure alignment with audit requirements and enterprise security standards. You will also manage and optimise Cisco Secure Firewall (FTD/FMC) environments, including IPS enablement, logging, and operational firewall governance.

This is a hands‑on technical leadership role requiring strong firewall engineering expertise and the ability to deliver structured remediation across complex enterprise environments.

• Proven experience delivering large‑scale segmentation and firewall remediation programmes, including leading end‑to‑end delivery within complex enterprise environments. Candidates must demonstrate familiarity with relevant technologies, programme scope, and measurable outcomes achieved.

• Hands‑on expertise with Cisco Secure Firewall technologies (FTD/FMC), IPS, and network segmentation, with the ability to operate confidently in complex, multi‑vendor or multi‑site environments. Candidates should be able to reference real‑world scenarios where they provided advanced support or delivered technical improvements.
