Configuring Allowed Domains & Whitelisting

Before you start

• ✓You need the IT Admin role to access these settings.
• ✓Configure allowed domains before inviting users. Accounts registered with unauthorized email addresses will need to be removed and re-invited.
• ✓Have your network firewall or proxy documentation available if you're configuring whitelisting — you'll need APBnet's domain list and IP ranges from the settings panel.

Part 1 — Allowed email domains

Allowed domains restrict which email addresses can register an APBnet account at your agency. Only users with an email address matching an allowed domain can create an account.

1. 1

   Open IT Admin Settings and select Allowed Domains.

2. 2

   Add your agency's primary email domain.

   Enter the domain without the @ symbol — for example, citypolice.gov. Save and confirm. All accounts with that domain can now register.

3. 3

   Add additional domains for contractors or partners if needed.

   If your agency uses approved IT contractors or other authorized staff who have different email domains, add those domains separately. Each domain is listed and can be removed independently.

4. 4

   (Optional) Configure Single Sign-On (SSO).

   If your agency uses SSO — Active Directory, Okta, or a similar provider — APBnet supports SSO integration. Configure it in the SSO tab within IT Admin settings. Users signed in through SSO don't need a separate APBnet password. Contact APBnet support for the SAML or OIDC configuration values you'll need.

Part 2 — Network whitelisting

If your agency filters outbound traffic through a firewall or proxy, you may need to whitelist APBnet's domains and IP ranges so the platform works without interruption — especially for push notifications and real-time updates.

1. 5

   Open the Network Whitelisting tab in IT Admin settings.

   This tab lists APBnet's domains and IP ranges that should be allowed through your firewall or proxy. The list is current — check back after major APBnet updates.

2. 6

   Add the listed domains and IP ranges to your agency's firewall or proxy allowlist.

   This is done in your existing network infrastructure tools — not inside APBnet. Use the listed values as your reference. If users report that push notifications aren't arriving or real-time updates are slow, network blocking is a common cause.
