RunZero Sites

Overview

Sites are the primary organizational unit in RunZero. Each site represents a network boundary -- typically a client location, office, data center, or cloud environment. Sites contain assets, define scan targets, and have explorers assigned for discovery. For MSPs, each client typically maps to one or more sites.

Key Concepts

Site Structure

Organization (RunZero Account)
  +-- Site: "ACME HQ"
  |     +-- Explorer: acme-hq-scanner
  |     +-- Assets: 342
  |     +-- Subnets: 192.168.0.0/16
  |
  +-- Site: "ACME Branch - Denver"
  |     +-- Explorer: acme-den-scanner
  |     +-- Assets: 58
  |     +-- Subnets: 10.10.0.0/24
  |
  +-- Site: "ACME Cloud - Azure"
        +-- Explorer: hosted-explorer
        +-- Assets: 127
        +-- Subnets: (cloud connector)

Site Scoping

Each site defines its network scope:

• Subnets -- IP ranges that belong to this site
• Exclusions -- IP ranges to skip during scans
• Auto-assignment -- Assets are assigned to sites based on where they are discovered

Explorer Assignment

Each site needs at least one explorer to perform scans:

• Managed explorers are deployed on the client's network
• Hosted explorers scan from RunZero's cloud
• Multiple explorers can be assigned to a single site

API Patterns

List Sites

runzero_sites_list

Parameters:

• count -- Results per page
• offset -- Pagination offset

Example response:

{
  "sites": [
    {
      "id": "site-uuid-456",
      "name": "ACME HQ",
      "description": "ACME Corp headquarters - main office",
      "scope": "192.168.0.0/16",
      "excludes": "192.168.255.0/24",
      "asset_count": 342,
      "service_count": 1205,
      "explorer_count": 1,
      "created_at": "2025-06-01T00:00:00Z",
      "updated_at": "2026-03-27T08:30:00Z"
    }
  ]
}

Get Site Details

runzero_sites_get

Parameters:

• site_id -- The specific site UUID

Returns full site details including scope, exclusions, asset/service counts, and assigned explorers.

Create a Site

runzero_sites_create

Parameters:

• name -- Site name (required)
• description -- Human-readable description
• scope -- Network scope (CIDR ranges)
• excludes -- Excluded ranges

Update a Site

runzero_sites_update

Parameters:

• site_id -- Site to update (required)
• name -- Updated name
• description -- Updated description
• scope -- Updated network scope
• excludes -- Updated exclusions

Common Workflows

Client Onboarding

1. Create a site for the new client: runzero_sites_create
2. Define the network scope (subnets to scan)
3. Deploy a managed explorer on the client's network
4. Run an initial discovery scan
5. Review discovered assets and services

Site Overview Report

1. Call runzero_sites_get for the target site
2. Retrieve asset count, service count, and scope
3. List recent scans for the site via runzero_tasks_list
4. Summarize asset types and OS distribution
5. Present findings with scan coverage analysis

Multi-Site Client Review

1. Call runzero_sites_list to get all sites
2. For each client, aggregate asset and service counts
3. Check explorer health per site
4. Identify sites with stale scan data
5. Generate cross-site summary

Scope Expansion

1. Get current site scope via runzero_sites_get
2. Add new subnets to the scope
3. Update the site with runzero_sites_update
4. Schedule a scan of the new subnets
5. Review newly discovered assets

Error Handling

Site Not Found

Cause: Invalid site UUID Solution: List all sites and verify the ID

Explorer Not Assigned

Cause: Site has no explorer; scans cannot run Solution: Deploy a managed explorer or assign a hosted explorer

Overlapping Scope

Cause: Two sites have overlapping subnets Solution: Review and adjust site scopes to avoid duplicate asset assignment

Best Practices

• Name sites descriptively with client name and location
• Define scope precisely to avoid scanning unrelated networks
• Use exclusions to skip sensitive or restricted ranges
• Ensure every site has at least one healthy explorer
• Review site asset counts after each scan for anomalies
• Map sites to PSA organizations for consistent client management
