Network Discovery (On-Premise)

Discovering on-premise devices—those not accessible via external networks or cloud platforms—requires manual intervention. Unlike automated discovery via cloud APIs (available for Azure, AWS, etc.), on-premise resources must be scanned using a local tool that runs within your network.

Here’s how to configure and execute on-premise network discovery using Prancer:

Step 1: Initiate the Autonomous Wizard (On‑Premise)

1. In the Prancer portal, launch the Autonomous Security Wizard from the left navigation pane.

2. On the first page, select On‑premise as the target environment.

3. Provide a meaningful Collection Name to organize the inventory results, then click Next.

Step 2: Define Network Scope

1. On the next screen, specify your scanning parameters:

CIDR Block(s) for the on-premise network segments you wish to include (e.g., 192.168.1.0/24).

Any IP exclusions, such as key infrastructure or sensitive devices not to be scanned.

2. Click Submit when ready.

You can add multiple CIDR blocks to cover segmented environments.

Step 3: Obtain and Run the Discovery Command

1. After submission, you’ll receive an on-screen command specifically generated for your environment. It looks something like this:

prancer‑pac discovery ‑i playground ‑t 6550b14a94d64b53ab872b3d18c543db ‑c 68953694f39e25228a282154

2. Copy the provided command and close the wizard.

3. Log into a Linux machine within your on-premise network that has access to all devices you want to scan.

4. Paste the command into the terminal and execute it.

Note: The Prancer on-premise discovery tool currently supports only Linux distributions. If you need support for other operating systems (like Windows or macOS), please contact Prancer support to request a compatible binary.

Step 4: Wait for Discovery Completion

Depending on the size and complexity of your network, the discovery process may take some time. During this phase, the tool scans IP addresses across the specified subnets, identifies reachable nodes, and assembles an inventory.

Step 5: Review Discovered Assets in the Portal

1. After the discovery process completes, return to the Prancer portal.

2. Navigate to the Collection Management or Inventory page.

3. A new inventory list will appear, showing all the nodes discovered during the scan.

These discovered devices are now available for further actions—such as initiating pentests or including them in subsequent inventory workflows.
