01
Client Profile & Background
A leading retail chain in Indonesia with over 200 stores across Java, Sumatra, and Kalimantan, specializing in fast-moving consumer goods (FMCG) and electronics. The company operates a central warehouse in Cikarang and regional distribution centers in Surabaya and Medan. With annual revenue exceeding IDR 5 trillion, the retailer serves millions of customers monthly through both physical stores and an e-commerce platform. The IT environment consists of legacy on-premise servers running ERP and POS applications, with a mix of unmanaged switches and consumer-grade WiFi at each store. The company recently secured Series C funding to accelerate digital transformation, including a network refresh to support real-time analytics, centralized inventory management, and omnichannel fulfillment. The goal is to unify all store networks under a single, cloud-managed architecture to improve operational efficiency and customer experience.
The existing network infrastructure was fragmented: each store had its own ISP contract, with varying bandwidth (20-50 Mbps) and no redundancy. This led to frequent POS downtime during peak hours, especially in stores with high foot traffic. The central IT team in Jakarta had no visibility into store-level network performance, making troubleshooting slow and reactive. To support the rollout of a new cloud-based ERP system (SAP S/4HANA) and a loyalty app, the retailer needed a network that could guarantee 99.9% uptime and handle 300+ concurrent devices per store, including tablets for staff, digital signage, and IoT sensors for cold chain monitoring.

Technical Challenge
The primary technical challenge was ensuring high availability and low latency across 200 geographically dispersed stores, many in areas with limited fiber optic infrastructure. Over 30% of stores relied on single-ISP DSL connections with average uptime of 95%, causing POS outages lasting 2-4 hours monthly. The existing network had no failover mechanism, and backup 4G LTE was only available in 20% of locations. Additionally, the legacy network switches (unmanaged, 100Mbps) could not handle the bandwidth required for video analytics and real-time inventory updates. The retailer needed to support 1Gbps uplinks per store, with the ability to burst to 2Gbps during promotions.
Another critical issue was network security: each store had a flat network with no segmentation between POS terminals, employee WiFi, and guest WiFi. This exposed the company to risks like ransomware attacks and data breaches. A recent audit revealed that 15% of stores had unauthorized devices connected to the network, including rogue access points. The rollout had to enforce strict access control policies, including 802.1X authentication for all corporate devices and captive portal for guest WiFi. Furthermore, the network needed to comply with Indonesia's Personal Data Protection Law (UU PDP), requiring encryption of customer data in transit and at rest. The legacy network could not meet these requirements, necessitating a complete overhaul with advanced security features like IPS/IDS and SSL inspection.

Implemented Solution
Intilogy designed and deployed a standardized network architecture for all 200 stores, leveraging Cisco Meraki for cloud-managed WiFi and switching, Ruijie RG-S2928G-E switches for cost-effective edge connectivity, and Fortinet FortiGate 60F for SD-WAN and security. Each store is equipped with dual WAN links: primary fiber (1Gbps from Telkom) and backup 4G LTE (from XL Axiata) with automatic failover via FortiGate SD-WAN. The network uses VLANs to segment POS, corporate, guest, and IoT traffic, with strict firewall policies enforced centrally from the FortiManager in Jakarta. For high-density WiFi, each store deploys 4-6 Cisco Meraki MR46 access points, supporting 802.11ax (WiFi 6) to handle up to 500 concurrent clients with seamless roaming.
The solution includes a centralized monitoring platform using Networking analytics from Cisco Meraki Dashboard, providing real-time visibility into bandwidth usage, application performance, and security events. For backup and disaster recovery, the retailer uses Veeam Backup & Replication to replicate POS data to a Synology NAS at the central data center every 15 minutes, with additional cloud backup to AWS Jakarta region. The rollout was completed in 6 months, with a phased approach: 50 stores per month, using pre-configured network templates to reduce on-site configuration time. Each store's deployment took 2 days, including cabling, installation, and testing.
04
Results & ROI
The network retail rollout delivered significant improvements in uptime, performance, and security. Store network availability increased from 95% to 99.99%, reducing POS downtime from 4 hours per month to under 5 minutes. The dual WAN links with SD-WAN ensured seamless failover, with an average switchover time of 8 seconds. Bandwidth per store increased from 50Mbps to 1Gbps, enabling real-time video analytics and faster transaction processing. The new WiFi 6 network supports 500+ concurrent devices per store, improving staff productivity and customer satisfaction (NPS score improved by 15 points).
From a security perspective, the number of security incidents dropped by 90% after implementing Fortinet's next-generation firewall and intrusion prevention. The centralized management reduced IT operational costs by 30%, as the team can now troubleshoot and configure all stores remotely. The ROI was realized within 12 months, driven by reduced downtime (saving IDR 2 billion annually in lost sales), lower bandwidth costs (through SD-WAN optimization), and improved inventory accuracy (reducing stockouts by 20%). The retailer is now planning to expand the network to 50 new stores in 2024, using the same standardized architecture. This project demonstrates how a well-executed network retail rollout can transform a traditional retailer into a digital enterprise, ready for omnichannel growth.
