An event driven computing system generates selected benefit packages that include benefits that are drawn from multiple marketplace platforms and diverse product categories while also protecting consumer information. The event driven computing system may include one or more list generation engines that are each built to generate curated lists of benefits associated with one or more corresponding benefit package programs. The event driven system may then pass the curated lists and an identifier associated with a recipient of the benefit package to a secure customization engine that personalizes the curated sets of benefits to individual consumers based on consumer data. The event driven system can then use the personalized sets of benefits to select benefits for inclusion in the benefit package that are individually tailored to the recipient.
