01
Client Profile & Background
A multinational manufacturing company with factories in Bekasi and Cikarang operates a sprawling network of over 500 switches, 200 access points, and 50 firewalls across multiple sites. The IT team manages a mix of legacy and modern equipment from vendors like Cisco, Fortinet, and Ruijie. The company's network supports critical production systems, inventory management, and real-time quality control. With 24/7 operations, any network downtime directly impacts production output and order fulfillment. The existing monitoring setup relied on basic SNMP polling with limited visibility, causing delayed detection of issues such as port flapping, high CPU utilization, and link saturation. The lack of centralized monitoring forced the IT team to manually check each device, leading to prolonged outages and increased operational costs.
The company's growth strategy involved expanding to new facilities in Karawang and adopting cloud-based ERP systems. This required a scalable network monitoring solution that could provide end-to-end visibility, automate incident management, and support multi-vendor environments. The IT leadership recognized that a traditional NOC approach with 24/7 monitoring would be essential to maintain service levels and support digital transformation initiatives.
02
Technical Challenge
The manufacturing network faced several critical challenges. First, the mean time to detect (MTTD) network failures was over 30 minutes, as alerts were generated only after threshold-based polling intervals. For example, a switch port failure in the production line caused a 45-minute delay before the IT team was notified, resulting in 12 hours of cumulative downtime per month. Second, the lack of correlation between network events and application performance made root cause analysis difficult. For instance, a sudden spike in latency was often misattributed to the WAN link, while the actual cause was a misconfigured QoS policy on a core switch. Third, the network experienced frequent broadcast storms due to looped connections, which took hours to isolate because of insufficient topology mapping. Finally, the security team required integration with firewall logs to detect anomalies, but the existing monitoring system could not parse syslog data from Fortinet devices. These issues collectively increased operational costs by 20% and reduced overall network reliability to 99.5%.
The company also faced compliance requirements from industry regulations that mandated 99.99% uptime for production systems. The existing monitoring gaps made it impossible to meet these SLAs, risking penalties and loss of business. The IT team needed a solution that could provide real-time visibility, automated alerting with severity levels, and historical reporting for capacity planning.

Implemented Solution
Intilogy designed and deployed a comprehensive Network Monitoring NOC using Networking monitoring platform paired with Cisco Catalyst Center and Fortinet FortiAnalyzer. The solution included deploying SNMP v3 with encryption across all managed devices, enabling secure polling of performance metrics. NetFlow was enabled on core routers to analyze traffic patterns, while syslog from firewalls and switches was centralized in a SIEM-like dashboard. The monitoring platform was configured with custom thresholds for latency (under 10ms), packet loss (under 0.5%), and bandwidth utilization (under 80%). Automated incident workflows were integrated with the company's ServiceNow ITSM, creating tickets for critical alerts and escalating to on-call engineers via SMS and email. A network topology map was auto-discovered using LLDP and CDP, providing a real-time view of device interconnections. Additionally, the solution included Enterprise WiFi monitoring for the 200 access points, tracking client density and channel utilization. The NOC was staffed 24/7 by Intilogy's engineers, who performed proactive health checks and monthly reporting.
To address security concerns, the solution integrated with Fortinet FortiGate logs to detect DDoS attacks and anomalous traffic patterns. The monitoring platform also supported Ruijie switches, which were deployed in the new Karawang facility. A dedicated dashboard was created for the IT team, showing real-time KPIs such as network availability, top talkers, and interface errors. The implementation was completed in 8 weeks, with minimal disruption to ongoing operations.
04
Results & ROI
Post-implementation, the manufacturing company achieved a 90% reduction in MTTD from 30 minutes to under 3 minutes, and MTTR decreased from 4 hours to 45 minutes. Network availability improved from 99.5% to 99.99%, eliminating unplanned downtime. The automated incident management reduced manual effort by 60%, saving an estimated 120 man-hours per month. The ability to correlate network events with application performance enabled the IT team to proactively resolve issues before they affected production. For example, a recurring QoS misconfiguration was identified and fixed, reducing latency spikes by 80%. The historical reporting facilitated capacity planning, allowing the company to right-size bandwidth for the new Karawang facility, saving 15% on WAN costs. Additionally, the integration with Fortinet logs improved security posture, with a 40% faster response to potential threats. Overall, the company reported a 200% ROI within 12 months, driven by reduced downtime costs and operational efficiencies. The NOC solution also supported the company's digital transformation by providing a scalable foundation for IoT and cloud adoption.
The success of this implementation led the company to extend monitoring to their Enterprise CCTV system and HCI infrastructure, further consolidating visibility. The IT team now uses the NOC dashboard for monthly business reviews, demonstrating the value of network reliability to stakeholders.
