OX Broker

OX Broker is a lightweight service deployed in your environment that enables OX Security to securely access and scan your internal resources without requiring any inbound firewall rules or network exposure.

Rather than opening ports to OX Security, OX Broker Client initiates a single outbound HTTPS connection from your environment to the OX Broker Server. OX Security then routes all requests through that established connection, ensuring that your internal resources remain fully isolated from the public internet while still being accessible to the OX platform.

Architecture

1. The broker client initiates an outbound-only HTTPS connection to the OX Broker Server; no inbound firewall rules are required.

2. OX Security routes requests back through the reverse tunnel to the broker client.

3. The broker client forwards the authenticated request to the target internal connector.

Prerequisites

Before you begin, contact an OX Security Customer Success representative for feature enablement.

OX Broker can be installed using Docker Compose on a Linux host or using a Helm chart on a Kubernetes cluster.

Ensure your environment meets the following requirements based on your chosen method

Linux host or Kubernetes node :

Requirement Type	Details
Operating System	Ubuntu 22.04 or later, RHEL 9 or later
Hardware	Minimum: 4 GB RAM, 2 CPU cores, 10 GB of available disk space
Network Requirements	Connectivity to your internal connectors from the host/node. Outgoing traffic on port 443 to the address provided by OX. Outgoing traffic to Docker Hub for pulling container images. Share the public IP address of the host/node with OX. Proxy: If your traffic is routed through a proxy, ensure port 443 HTTPS is allowed for outbound communication to the OX environment. Share the proxy IP address with OX Security.

Docker Compose requirements

Requirement Type	Details
Software	Docker Engine and Docker Compose V2
Access	Root access or sudo available

To verify your machine is configured correctly, download and run the readiness script:

curl -fsSL https://installer.broker.ox.security/universal/oxbroker_readiness.sh -o oxbroker_readiness.sh
chmod +x oxbroker_readiness.sh
sudo ./oxbroker_readiness.sh

Helm requirements

Requirement Type	Details
Kubernetes	Access to a Kubernetes cluster
Software	Helm version 3 or later, kubectl configured for the target cluster

Installing OX Broker

Choose the method that matches your deployment environment and follow the relevant installation procedure:

• Docker Compose on a Linux host or virtual machine

• Helm chart on a Kubernetes cluster

Install OX Broker Using Docker Compose

To install OX Broker using Docker Compose:

1. Download the installation script.

   curl -fsSL https://installer.broker.ox.security/universal/oxbroker_installer_universal.sh -o oxbroker_install.sh
   chmod +x oxbroker_install.sh

2. Run the script as root, providing the OX Broker server address supplied by OX Security.

sudo ./oxbroker_install.sh --host <BROKER_HOST>

1. If your environment routes traffic through a corporate proxy, add the --proxy flag. The script generates an SSH key pair and credentials, and displays them on screen.

sudo ./oxbroker_install.sh --host <BROKER_HOST> --proxy <PROXY_HOST>:<PROXY_PORT>

1. Send the public key to OX Security support and save the credentials in a safe location.

2. Once OX Security confirms the key has been registered, press p to proceed. The script starts the OX Broker services automatically.

Install OX Broker Using Helm

This installation method deploys OX Broker into a Kubernetes cluster using a Helm chart.

To install OX Broker using Helm:

1. Add the OX Security Helm repository and update it.

helm repo add ox https://charts.cloud.ox.security
helm repo update

1. Verify the chart is available.

helm search repo ox/oxbroker

1. Generate authentication keys locally.

ssh-keygen -q -t rsa -b 4096 -f oxbroker-key -N "" -C "oxbroker@k8s" && cat oxbroker-key.pub

1. Send the public key (oxbroker-key.pub) to OX Security and wait for confirmation and the assigned OX Broker server address.

2. Create a Kubernetes namespace and secret containing the authentication keys.

kubectl create namespace oxbroker
kubectl create secret generic oxbroker-keys -n oxbroker \
  --from-file=private-key=oxbroker-key \
  --from-file=public-key=oxbroker-key.pub

1. Install the Helm chart using the broker server address provided by OX Security.

helm install oxbroker ox/oxbroker -n oxbroker \
  --set oxbroker.remoteHost=<BROKER_SERVER_ADDRESS>

To configure proxy settings, add the following:

  --set proxy.enabled=true \
  --set proxy.host=<PROXY_HOST> \
  --set proxy.port=<PROXY_PORT>

Note: <PROXY_HOST> must be the FQDN only, for example, proxy.company.com. Do not include the protocol or port.

Verifying OX Broker

To confirm that OX Broker is running:

• For Docker Compose installations:

docker compose ps

• For Helm installations:

kubectl get pods -n oxbroker

Configuring OX Broker

After installation completes, use with either method:

1. Log in to the OX Security portal.

2. Go to the relevant connector.

3. Select Broker as the connection method.

Provide the following details:

Field	Details
Internal resource URL	Provide the connector URL
Token	Add your connector token
User	The user that was generated by the OX script
Password	The password that was generated by the OX script
Bypass SSL Verification (not recommended)	Enable this option if your environment lacks a proper certificate or uses a self-signed certificate

Upgrading OX Broker Using Helm

To upgrade OX Broker using Helm:

1. Update the OX Security Helm repository.

helm repo update ox
