IP Optimization for Explicit Proxy Users- Proxy Deployments

Enhancement to reduce the overall number of IP addresses in your deployment and to enable faster onboarding of Prisma Access tenants.
IP address 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 and enabling faster onboarding of Prisma Access tenants.
IP Stickiness
In Explicit Proxy, when traffic egresses from a Prisma Access, it uses an external IP address being allocated to the Explicit Proxy security processing node (EP-SPN). This means that multiple HTTP connections from the same user session can use different external IP addresses because they pass-through different EP-SPN. Once the IP address stickiness feature is enabled, the traffic from a user always egresses out using the same IP address. No additional configuration is required for this feature.
Simplify SaaS Onboarding
Adding a Prisma Access location or experiencing a scaling event at an existing Prisma Access location or the large deployments could lead to higher number of IP addresses being allocated to the explicit proxy security processing node (EP-SPN). It's a best practice to retrieve the new egress and gateway IP addresses and add them to an allow list of the SaaS application or in your network to avoid disruption. This can result in a situation where you're managing a large number of Prisma Access IP addresses. IP address optimization help reduces the number of Prisma Access IP addresses you have to manage. This feature also helps in large deployments.
