Multi-Site Network
Rebuild (4 Sites)

The client operated four physical ag-operations sites that had grown independently over time. Different hardware at every location. Different wireless behavior. Different switch configurations. Different firewall rules. Some equipment was consumer-grade. Some was end-of-life. Some had simply been inherited from whoever touched the environment last. There was no common architecture tying the locations together.

The network topology itself was flat across nearly every site. Business systems, servers, guest devices, security cameras, management traffic, housing networks, and operational equipment all existed on the same shared broadcast space with little or no segmentation. Operationally, that created instability and troubleshooting complexity. From a security standpoint, it meant there was effectively no containment boundary between systems that should never have been sharing the same network in the first place.

The support burden compounded over time because every site behaved differently. A problem at Site 1 did not translate cleanly to Site 2 because the environments were architecturally unrelated. Every support call required relearning that location's specific version of chaos before the actual issue could even be diagnosed. The infrastructure had become four separate operational problems instead of one manageable system.

AOtech performed a full rip-and-replace network rebuild across all four locations with the goal of standardization first, hardware second. The architecture was designed once, then deployed uniformly across every site so operational management, troubleshooting, and policy enforcement would behave consistently regardless of location.

Sophos firewalls were deployed at every site to provide unified threat management, centralized policy enforcement, and consistent security controls across the environment. UniFi switching and wireless infrastructure replaced the fragmented network hardware stack, giving the client centralized visibility into switching, wireless health, client behavior, and site-wide network operations from a single management plane.

The core of the rebuild was a standardized 7-VLAN architecture replicated identically across all locations. Business systems, servers, guest traffic, security systems, management infrastructure, housing networks, and operational IoT/automation devices were all segmented into dedicated network boundaries with defined policy control between them. The point was not simply segmentation for its own sake. The point was operational predictability. Site 1 and Site 4 now follow the same architectural rules, which means management knowledge transfers directly between locations instead of being rebuilt from scratch every time.

The environment shifted from four independently managed networks into a single operational architecture distributed across four locations. Troubleshooting became dramatically more predictable because the underlying infrastructure now behaves consistently everywhere. The team no longer spends time deciphering site-specific networking decisions before they can solve the actual problem.

Security posture improved substantially through segmentation alone. Guest traffic, operational systems, cameras, management interfaces, and business workloads now operate within defined network boundaries instead of sharing unrestricted lateral access across flat infrastructure. Problems that previously could spread freely between systems now encounter controlled segmentation points and policy enforcement layers.

The project also fundamentally changed the long-term support model. Because AOtech remains engaged as the client's managed IT provider, the standardization matters operationally every single day after deployment — not just during the rebuild itself. New devices, troubleshooting workflows, policy updates, wireless expansion, and future site growth now happen against a known architectural baseline instead of accumulating more inconsistency over time.
