# Backplane Control

> Group rate limiting and IP restrictions for Virtual APIs.

<Note>
  Backplane Control is **coming soon**. We'd love to hear about your use case — [get in touch](mailto:hello@dataharbor.co?subject=Interest%20in%20Backplane%20Control).

# Backplane Control

**Protect your source. Automatically.**

Backplane Control monitors the health of your upstream data source and adapts request flow in real time — throttling, queuing, or shedding load before your source feels the pressure. Combined with group rate limiting and IP restrictions, it gives you infrastructure-level protection without writing infrastructure code.

## Adaptive load management

DataHarbor continuously monitors your upstream API's response times, error rates, and availability. When conditions degrade, Backplane Control automatically adjusts how much traffic it forwards — scaling back before your source becomes overwhelmed, and ramping back up as it recovers.

You set the boundaries. DataHarbor enforces them in real time.

## Group rate limiting

Control request volume per consumer group across your Virtual APIs. Set limits per partner, per team, or per use case — so one consumer can't starve others.

## IP restrictions

Restrict access to specific IP ranges to ensure only authorized networks can reach your data.
