WCF Installation

The WCF Agent integrates with the OneFirewall Platform to:

• Ingest security events from SIEMs (via syslog)
• Serve threat feeds to firewalls (FortiGate, pfSense, etc.)
• Automate blocking of malicious activity

This guide shows you how to deploy the WCF Agent on your own infrastructure.

​

1. Prerequisites

​

1.1 Virtual Machine Specifications

• RAM: 8 GB (minimum 4 GB)
• vCPU: 4 cores (minimum 2 cores)
• Disk: 50 GB (minimum 20 GB)

​

1.2 Network Requirements

​

2. Install Docker & Docker Compose

# On Debian/Ubuntu
sudo apt update
sudo apt install -y docker.io
sudo systemctl enable --now docker

# Install Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | jq -r '.tag_name')/docker-compose-$(uname -s)-$(uname -m)" \
  -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

​

3. Prepare Your Deployment Directory

mkdir -p ~/wcf-agent
cd ~/wcf-agent

1. Download the WCF Agent Docker image into this folder.
2. Obtain your config.json from OneFirewall’s Install Agent page.
3. Place config.json in ~/wcf-agent/.

​

4. Create docker-compose.yml

version: '3'
services:
  onefirewall-wcf-agent:
    image: app.onefirewall.com/wcf-agent:v4
    restart: always
    ports:
      - 8085:8080
    volumes:
      - "/tmp/log/:/var/log/:ro"
      - "./onefirewall/config:/opt/onefirewall/WCF-Agent-latest/config/:rw"
      - "./onefirewall/db:/opt/onefirewall/WCF-Agent-latest/db/:rw"
    command: >
      bash -x init.sh

​

5. Launch the Agent

docker compose up -d
docker-compose logs -f wcf-agent

1. docker compose up -d runs containers in the background.
2. docker compose logs -f streams the agent’s output for troubleshooting.

​
