From MainWP you can manage Security Ninja firewall whitelist and blacklist entries on Pro child sites without opening each site’s wp-admin.
Requirements
- Security Ninja for MainWP Pro on the Dashboard
- Security Ninja Pro on the child site(s)
- Child sites at Security Ninja 5.285 or newer for remote IP actions
- Security Ninja for MainWP 2.1.0+ (bulk Manage IPs from 2.2.0)
Per-site IP management
- Open the child site’s Security Ninja page in MainWP (from the Sites table or the extension).
- Open the IP management tab.
- Review synced whitelist, blacklist, and temporary blocks.
- Enter an IP or CIDR, choose whitelist or blacklist, add an optional note, then click Add to list.
- Remove entries or lift local / 404 Guard bans when those actions are available for the synced data.
- Sync the site if the table looks stale after remote changes.
Remote IP management needs a successful sync so MainWP has the child’s IP lists.

Bulk Manage IPs
- Go to Sites → Manage Sites and select the Pro child sites you want to update.
- Choose Manage IPs (Security Ninja).
- Enter an IP or CIDR, optional note, and whitelist or blacklist.
- Confirm. Each selected site that meets the version and Pro requirements gets the entry.
- Run MainWP Sync on the same selection so the dashboard IP tables refresh.

Sites below 5.285 or without Pro are skipped with a message.
