Bloky works with rules. You choose which countries, IP addresses or buyers to block, and it blocks them on your store or at checkout. Each step up in price unlocks more kinds of rules.
The weak spot of any rule is bots that look normal. Bots that use ordinary home internet connections in your own country pass location rules. Skyfense checks how each visitor actually behaves on your store, so it can catch software pretending to be a shopper even when it comes from a normal place.
The other big difference is ads. If you pay Google, Facebook or TikTok for clicks, Skyfense shows you which of those clicks were bots, and what they cost you.
