Best bot detection software for ecommerce checkout in 2026

At checkout, bots mean scalping, inventory hoarding, and card testing, and the best detection recognises the automated device behind mass add-to-cart and payment attempts instead of just rate-limiting IPs, which scalpers rotate anyway. cside reads 250+ per-session signals to spot headless and automated browsers and the repeated devices driving these runs, across rotated IPs and accounts. It loads asynchronously from one lightweight first-party script, so it adds no perceptible latency to checkout, and the same engine also watches checkout scripts for skimming and PCI DSS 4.0.1.
