Case Study: Bank of Marin achieves faster application performance and carrier independence with Palo Alto Networks Prisma SD‑WAN

Bank of Marin Improves Application Performance with Prisma SD-WAN

Bank of Marin, a community bank in Marin County, California, was constrained by a legacy WAN built on MPLS links (1.5–10 Mbps) and complex low-level network management. These limits degraded core application performance, slowed branch provisioning, and forced dependence on carriers and specialized networking skills.

By deploying Palo Alto Networks Prisma SD‑WAN, the bank securely added high‑speed business internet at branches, adopted a policy‑driven, transport‑agnostic WAN, and used preconfigured Instant‑On devices for faster rollouts. The result: significantly better core banking application performance, greater bandwidth at lower cost, reduced carrier dependence, branch deployment times cut from ~90 days to about two weeks, and overall lower IT costs with improved employee productivity.
