New security layer to block card testing attacks, and other changes

Phased rollout of a new security layer in the checkout process

This week, we’re rolling out a new security layer that our CTO Dror Yaakov has been working on. It will prevent card testing attacks more accurately while letting legitimate purchases pass through.

We’re doing this in a phased manner to avoid surprises and to thoroughly test the system. Only a small percentage of requests will run through the new layer. Once we have enough data, we will let the system handle more requests, eventually replacing the existing one.

Other changes

• Some SEO-related updates to the blog.
• Improvements to some internal apps.
• Improved the checkout app’s email validation system.
