The weeks around the holidays are when many businesses make their year. They are also when fraud rises fastest, and for the same reason: everyone is buying, orders spike, and the unusual starts to look normal. A rushed checkout, an express-shipped gift to a different address, a card from abroad, all of it is ordinary in December, which is exactly why fraud hides in it.
Why the surge happens
Three pressures stack up. Order volume climbs, so your review team is stretched thin. Legitimate orders genuinely get more unusual, gifts, travel, new devices, so your normal rules throw more false alarms. And fraudsters know both of those things, so they time their heaviest activity for when you are least able to look closely.
Prepare before the peak, not during
The worst time to change your fraud screening is mid-surge, when you cannot tell whether a spike is a sale or an attack. Set up ahead of time:
- Baseline now. Log IP and BIN verdicts on orders through a normal week so you know what your ordinary mix looks like before volume distorts it.
- Automate the easy calls. Let clean orders, home connection, matching card and shipping country, flow through untouched so your humans can focus on the genuinely odd ones.
- Pre-write the rules for high-risk combinations: VPN plus prepaid card plus mismatched country, or many cards from one network in minutes.
Keep real customers moving
Over-tightening in peak season has its own cost: every genuine order you block is a sale lost at the one time of year it hurts most. The aim is a screen that quietly clears the obvious-good traffic and flags only the real outliers. Fraudex handles IP and BIN checks from a single key, fast enough to run on every order even at peak volume, so you can prepare the screen once and let it carry the season.
