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, leading to frustrated customers and lost sales. Bot operators exploit these situations for profit, often reselling items at inflated prices. Sneaker drops, concert tickets, and limited-edition releases are common targets. preventing-ticketing-bots/

How Prosopo Prevents Inventory Denial

Prosopo uses Procaptcha to detect and block automated behaviors during checkout or reservation flows. Common strategies include:

  • Identifying rapid, repeated add-to-cart actions
  • Monitoring unusual browsing patterns
  • Flagging multiple cart additions from the same IP or device
  • Challenging suspicious users with more rigorous verification

The signals we use are constantly updated to stay ahead of evolving bot tactics. Anyone using automated browsers such as Puppeteer or Selenium are blocked. Captcha Farms are detected and forced through challenging captchas.
