Getting Started with NISSI

Welcome to NISSI Command Center — your AI-powered cybersecurity platform. This guide walks you through the four setup steps shown on your Dashboard.

Step 1: Install the Agent

The NISSI Endpoint Agent monitors your devices for threats in real-time.

1. In Command Center, click Download Agent on the Dashboard (or go to AgentDownload in the sidebar)
2. You'll see the Python Agent — currently the production-ready option
3. Install the required Python dependencies:

pip install psutil requests yara-python scapy

4. Download nissi-agent.py from the Command Center
5. Set your credentials and run:

export NISSI_DEVICE_ID="your-device-id"
export NISSI_API_KEY="your-api-key"
python3 nissi-agent.py

The agent runs continuously and reports to NISSI every 60 seconds.

Step 2: Register Your Devices
