Is 90 days enough to replace VPN entirely?

Often no for large banks. 90 days is enough to pilot, scale core cohorts, wire SOC telemetry, and start VPN retirement — Digvijay plans for parallel access where needed.

Prisma Access or Zscaler for a bank?

Depends on estate and skills. Digvijay’s deepest delivery proof is Palo Alto Prisma ZTNA/SASE at J.P. Morgan; he also implements Cisco SASE components and advises based on existing NGFW/identity investments.

When should AI analytics start?

As soon as telemetry is trustworthy — typically during/after pilot — so MTTD gains compound during scale. Digvijay’s pattern delivered 30% MTTD reduction with AI-driven SASE analytics.

What certifications matter for SASE consultants?

Platform credentials (e.g. PCNSE) plus operating experience in regulated environments. Digvijay is PCNSE-certified and has delivered under financial-sector constraints.

A 90-Day SASE and Prisma Access Rollout for Financial Institutions

By Digvijay Parmar · AI Security & Zero Trust Architect · Last updated 2026-08-01

A credible 90-day SASE program for financial institutions phases identity, pilot apps, parallel VPN/ZTNA, SOC telemetry, and AI analytics — not a weekend cutover. Digvijay Parmar designed and deployed Palo Alto Prisma ZTNA at J.P. Morgan, ran SASE PoCs under regulatory constraints, and engineered AI analytics that cut MTTD 30% and increased proactive risk mitigation 50%.

Buyer question: What does a realistic 90-day Prisma Access / SASE rollout look like for a bank or financial firm?

What should days 0–30 establish?

Inventory users/apps/exceptions, integrate identity (e.g. Entra ID / MFA), stand up Prisma Access / ZTNA design workshops, define success criteria and logging to SOC, and pick a pilot cohort. Digvijay’s financial-sector deployments start with regulatory and exception reality, not slideware.

Financial institutions fail SASE programs when exception apps and UDP paths are discovered after go-live. Digvijay’s Prisma ZTNA work at J.P. Morgan and Cisco SASE experience in Fortune 100 environments emphasize early exception mapping and posture (HIP) requirements.

What should days 31–60 deliver?

Pilot production cohorts on ZTNA, keep VPN parallel, tune split-tunnel/always-on/HIP policies, onboard first data-center or private-app paths, and measure user experience plus security signal quality before scale.

This is where most programs either earn trust or lose it. Digvijay favors department-by-department expansion with clear rollback and dual-stack access.

Begin AI analytics design against trustworthy telemetry — the same discipline that produced 30% MTTD reduction in his SASE analytics work.

Workstream	Exit criteria
Pilot users	Stable access + low ticket rate
Private apps	Connector HA + app allow-list validated
SOC	Prisma/SASE logs searchable in SIEM
Exceptions	Documented VPN residual list

What should days 61–90 finish?

Scale remaining cohorts, harden decryption/URL/security profiles as required, tune AI analytics for MTTD/proactive mitigation, begin VPN retirement for cleared apps, and hand over runbooks with evidence for audit.

Success is not “VPN off.” Success is least-privilege access with continuous verification, measurable detection, and an operations team that can change policy without outages.

Digvijay’s multi-vendor background (Prisma + Cisco SASE) helps when estates are mixed — common in global financial firms.
