Vercel's guide covers how to block malicious traffic using custom Firewall rules, set spend limits, and apply code optimizations. It recommends enabling Fluid compute to save up to 85% on function usage and notes that Image Optimization billing changed from unique source images to transformations at a lowered price.

## Evidence

Verbatim from https://vercel.com/blog/protecting-your-app-and-wallet-against-malicious-traffic:

> We strongly recommend enabling Fluid compute, which is a more cost-effective model for Vercel Functions. This can save up to 85% of your function usage for applications with many concurrent requests.
