What is a Denial of Inventory Attack?

A denial of inventory attack occurs when bots repeatedly add items to online carts or reservations without completing purchases. This locks up inventory and prevents real users from buying.

Why It Matters

Retailers lose revenue and reputation when inventory is artificially limited. Events and exclusive products are especially vulnerable.
