3. Advance secure network architecture: Partner with cybersecurity teams to improve segmentation, IDS/IPS alignment, zero‑trust controls and audit‑ready network practices.
4. Drive transformation workstreams: Lead network components of modernisation initiatives such as SD‑WAN, hybrid‑cloud connectivity, segmentation or platform upgrades.
5. Improve operational maturity: Introduce better monitoring, capacity planning, automation or SDN approaches where they can reduce risk, cost or manual effort.
