IP Optimization is a set of architectural enhancements that reduce the overall number of IP addresses in your deployment, simplifying your allow-listing workflows while improving resiliency and enabling faster onboarding of Prisma Access tenants.

Simpler Public IP Address allow-listing–Adding a Prisma Access location or experiencing a scaling event at an existing Prisma Access location could lead to new IP addresses being allocated to the mobile user security processing node (MU-SPN). It's a best practice to retrieve the new egress, gateway, and network load balancer IP addresses that Prisma Access assigns and add them to an allow list in your network to avoid SaaS application or corporate firewall disruption. This can result in a situation where you're managing a large number of IP addresses. IP Optimization reduces the number of IP addresses you have to manage.
