NetPulse — Security Monitoring & Anomaly Detection

NetPulse is a self-hosted network security monitoring dashboard that applies BTech knowledge of networking protocols to real-world security monitoring. It continuously polls network nodes using SNMP and ICMP, streams live telemetry over WebSockets, and applies anomaly detection to flag suspicious traffic patterns — port scans, unusual bandwidth spikes, and unexpected connection attempts. Unlike enterprise tools like PRTG or SolarWinds, NetPulse is lightweight, open-source, and deployable on a single machine — ideal for home labs, campus networks, and small infrastructure environments.

The Challenge

Most network monitoring solutions focus on availability and performance — not security. For a student or small team, there's a gap for a simple, self-hosted tool that combines network health monitoring with basic intrusion detection, without the overhead of enterprise SIEM systems.

The Solution

Results & Impact

• Real-time visibility into network node health and security events
• Anomaly detection flags port scans and unusual traffic patterns
• Live latency and packet-loss tracking per network segment
• SNMP-based interface utilisation monitoring for managed devices
• Deployable on any machine with Docker — no cloud required
