Prisma is simply protecting everything modern: your cloud, your remote workers, and your network connections. Have you heard of these acronyms? CSPM, CWP, CIEM, CNS, IAM, DLP, etc. Prisma is all that!
Prisma Access: Is a cloud-based firewall that connects and secure your on-prem, branch sites, and users globally. (this an oversimplified definition)
Prisma SD-WAN: Allows you to connect your on-prem and branch sites easily. It is not a firewall, it's a cloud-based router that connects everybody to everybody else. You no longer have to setup IPSec VPNs, and MPLS connections manually.
Prisma SASE: Prisma Access + Prisma SD-WAN
Prisma Cloud: Protects your public cloud – AWS, Azure, etc. Cloud Security Posture Management (CSPM) + Cloud Infrastructure Entitlement Management (CIEM) + cloud-based workload scanning.
Prisma Browser: Formerly "Talon", is a secure browser. Users can only use that browser to access your enterprise applications (Salesforce, Slack, Dropbox, Office365, and many many others). So users cannot use Firefox, Chrome, or anything else to access your enterpise SaaS applications.
