A single supply partner sending far more traffic than agreed can slow down or overload an exchange. The ADX gives you several layers of protection.
Built into the ADX
- Limits per partner: each partner is created with its own limit, for example 5,000 QPS.
- QPS limits per endpoint, added in v2.3 (June 2026).
- Traffic shaping: stop sending requests that nobody bids on, which keeps volume to buyers clean.
- Allow and block lists per partner.
Traffic Shield plugin
For stronger protection, the Traffic Shield plugin ($1,990 one-time, for SSP and ADX) gives each partner its own QPS cap and blocks floods automatically before they reach the rest of the platform. Details: Traffic Shield.
Capacity on rented plans
A rented or white label ADX includes up to 25,000 QPS for $500 a month, with 100,000 QPS for $1,900 or 150,000 QPS for $2,900. A licence or the source code runs on your own servers with no QPS limits.
Practical checklist
- Agree a daily volume and peak QPS with each new partner.
- Set that limit on the partner before going live.
- Turn on shaping once you know which traffic each buyer wants.
- Watch the bidstream monitor for timeouts after any change.
