Specialized Solutions

Software solutions for ISPs, networks, and enterprises

Production-ready systems we build for technical operations — from ISP billing and OLT management to network automation and security. Designed for businesses, not individual users.

ISP Billing & Management

A centralized billing system for ISPs and broadband operators — manage subscribers, invoices, and payments from one dashboard, with suspension and reactivation that run automatically based on billing status.

  • Scheduled auto-billing & invoicing
  • Centralized subscriber management

OLT ZTE C300/C320 Management

  • Guided ONU/ONT provisioning
  • Optical power & attenuation monitoring
  • Centralized GPON/FTTH management

Payment Gateway Integration

Connect your system to local payment channels like Midtrans, Xendit, QRIS, and Virtual Account. Payment status flows in automatically via webhook and reconciles straight to customer invoices.

  • PPPoE & hotspot vouchers
  • AAA & bandwidth management
  • RouterOS config automation

Network Monitoring & Looking Glass

A NOC dashboard to watch network health in real time — uptime and device monitoring via SNMP, plus a public BGP looking glass so your team and customers can verify routing from your network's side.

  • Real-time NOC dashboard
  • Uptime & SNMP monitoring
  • Public BGP looking glass

WhatsApp Gateway / Business API

Reach customers on the channel they check most. Send OTPs, transaction notifications, and scheduled broadcasts over WhatsApp, with a chatbot to handle routine questions automatically.

  • OTP & transaction notifications
  • Scheduled broadcasts
  • Automated chatbot

Cyber Security

Secure your business applications and infrastructure through security audits and penetration testing, followed by system hardening and ongoing security monitoring to catch anomalies early.
