Zero Trust Consulting
Zero Trust Consulting Built for Hybrid and Financial Environments
Digvijay Parmar is a Zero Trust consultant who has designed, deployed, and operationalized Zero Trust and SASE architectures for Fortune 100 enterprises and global financial institutions — including Palo Alto Prisma ZTNA at J.P. Morgan and microsegmentation validation that cut diagnostic latency by 75%.
What Zero Trust consulting should deliver
Zero Trust is not a product purchase. It is least privilege, continuous verification, and identity-aware segmentation enforced consistently across a hybrid estate. A Zero Trust consultant should be able to design the architecture, deploy it, and then prove it is actually working — not hand over a diagram and leave.
My approach treats Zero Trust as a first principle, not an afterthought. Least privilege, continuous verification, and identity-aware segmentation are designed in from the start, then validated deterministically against live policy and logs so the controls can be trusted.
Zero Trust work I have delivered
At J.P. Morgan I designed and deployed Palo Alto Prisma ZTNA to enforce least-privilege access and replace traditional VPN risk for a global financial institution, and engineered AI-driven analytics within the SASE architecture that produced a 30% reduction in MTTD and a 50% increase in proactive risk mitigation.
At Cisco Systems I implemented ZTNA and microsegmentation with Cisco security solutions to prevent unauthorized lateral movement, and configured Cisco SASE — CASB, ZTNA, and FWaaS — for Fortune 100 environments. At Point72 I operationalized Zero Trust controls via deterministic validation of identity-aware ACLs and microsegmentation, reducing diagnostic latency by 75% (45 minutes to under 5).
During COVID-19 I architected emergency Zero Trust remote access for healthcare, scaling Cisco AnyConnect VPN with posture validation under HIPAA — a real-world test of Zero Trust principles under pressure.
Why validation is the part most consultants skip
Most Zero Trust engagements stop at deployment. The harder problem is proving the controls hold: that identity-aware ACLs are actually enforced, that microsegmentation boundaries stop lateral movement, and that drift is detected before it becomes an incident.
I built an AI-Driven Security Investigation Platform that correlates firewall policy, Cisco ISE / NAC authorization logs, and BGP/OSPF routing data to validate microsegmentation boundaries and enrich access alerts. That is the layer that turns Zero Trust from an architecture diagram into a control you can prove.

Bring one real Zero Trust problem — a segmentation design you are unsure about, a ZTNA rollout that has stalled, or a control you cannot prove is enforced. You leave with a diagnosis, two or three concrete recommendations, and a written summary in 24 hours. No pitch.
What collaborators say
"Digvijay is very talented in Network Security and he comes up with different ideas to solve the problems, tracing an unknown network, understanding the situation and solving them. He introduces us to new ways to solve the issues and also makes our team aware of it."
— Vibhor Katiyar, Technical Operations Manager, Amazon Web Services
"Digvijay is conceptually and practically very sound in Cisco Technology. He is great in network troubleshooting as well, with a continuous thirst for progress and a superlative personality."

Frequently asked questions
- What does a Zero Trust consultant do?
- A Zero Trust consultant designs, deploys, and validates least-privilege, identity-aware, continuously verified access across a hybrid estate. Digvijay Parmar has delivered Prisma ZTNA at J.P. Morgan, Cisco SASE and microsegmentation at Cisco Systems, and Zero Trust validation at Point72 that cut diagnostic latency 75%.
- How long does a Zero Trust engagement take?
- Architecture and PoC for a defined scope can take weeks; full production deployment and validation is iterative. The free 40-minute Agentic AI Standup gives you a concrete diagnosis and direction for your specific Zero Trust problem before you commit to anything.
- Which Zero Trust platforms does Digvijay work with?
- Palo Alto Prisma Access and ZTNA, Cisco SASE (CASB, ZTNA, FWaaS), Cisco ISE for identity-aware access, Cisco Firepower/FTD, and Fortinet. He is PCNSE-certified on Palo Alto and holds Cisco Security Core and CCNA/CCNP credentials.
- How do you prove Zero Trust is actually enforced?
- By validating identity-aware ACLs and microsegmentation boundaries against live firewall policy, NAC authorization logs, and routing data — deterministically. Digvijay's AI-Driven Security Investigation Platform does exactly this, reducing time-to-answer on complex investigations from ~45 minutes to under 5.
- Is Zero Trust consulting different from SASE consulting?
- They overlap. SASE is the converged platform (SWG, CASB, FWaaS, ZTNA) that delivers Zero Trust for remote and branch access. Zero Trust is the architectural principle. Digvijay covers both — see the SASE / ZTNA consulting page for the platform side.
