IT Infrastructure Engineering
Hardened corporate network design, site-to-site VPN connectivity, multi-branch gateway routing, and proactive perimeter security policies engineered for zero-trust resilience.
Resilient Physical & Virtual Network Topology
Modern enterprises operate across corporate offices, fulfillment warehouses, and remote executive workstations. Ensuring seamless, authenticated communication between distributed facilities requires disciplined network engineering.
ALISH TECH audits, structures, and maintains enterprise networking equipment (switches, routers, firewalls, Wi-Fi access points). We configure encrypted IPsec and WireGuard tunnels between branches and central ERP servers, preventing eavesdropping and unauthorized access.
Site-to-Site Encrypted Tunnels (VPN)
Connecting warehouse scanner terminals and regional offices directly to headquarters databases over encrypted channels.
Perimeter Firewall Governance
Stateful packet inspection, intrusion prevention (IPS/IDS), isolated guest networks, and strict port filtering rules.
Hardware Lifecycle & Network Audits
Systematic asset inventory, firmware vulnerability patching, UPS power protection, and bandwidth QoS prioritization.
