AI Security Guide
Using AI to Validate Zero Trust Controls and Cut Diagnostic Latency
Zero Trust is only as strong as your ability to prove controls hold under real traffic and identity. Digvijay Parmar has delivered Palo Alto Prisma ZTNA at J.P. Morgan, Cisco SASE and microsegmentation at Cisco Systems, and AI-driven Zero Trust validation at Point72 that cut diagnostic latency 75%.
Why Zero Trust programs stall without validation
Many Zero Trust programs stop at architecture diagrams: identity-aware access, least privilege, and continuous verification written as principles. The hard part is proving that a path is denied, that segmentation holds after a change, and that an investigation does not take 45 minutes of manual correlation across firewalls, NAC, and routing.
AI helps when it is grounded in the same evidence a human investigator would use — policy, authorization logs, and topology — not when it invents a “Zero Trust score” from marketing data. Digvijay’s AI-Driven Security Investigation Platform correlates firewall policy, Cisco ISE / NAC authorization logs, and BGP/OSPF routing data to automate investigation workflows and validate Zero Trust segmentation.
What AI validation looks like in practice
At Point72, Digvijay builds AI-driven security automation that turns operational data into engineering insight. On complex investigations, that work reduced diagnostic latency by 75% — from roughly 45 minutes to under 5 — which is the difference between a control that is theoretically continuous and one your team can actually verify under pressure.
At J.P. Morgan, Digvijay engineered AI-driven analytics within a Palo Alto Prisma Access / SASE architecture, achieving a 30% reduction in mean time to detect and a 50% increase in proactive risk mitigation for a global financial institution. That is Zero Trust plus telemetry, not Zero Trust as a slogan.
If your estate is hybrid, insist on consultants who have shipped Prisma ZTNA, Cisco SASE, and microsegmentation in production — Digvijay’s path includes those exact platforms — and who can explain how AI recommendations stay inside change governance.
How to start without a multi-year program rewrite
Bring one validation problem to a free 40-minute Agentic AI Standup: a segmentation gap, a ZTNA exception path, or an investigation that still takes too long. You leave with a diagnosis and a written summary in 24 hours.
For engagement scope and Zero Trust consulting services, see the Zero Trust Consulting vertical. This guide focuses on the AI validation lens buyers should demand.
What collaborators say
"While working with Digvijay on the same network engineering team but different projects, he was very responsive and with detailed accurate information every time. No matter if it was requesting where to locate documentation, identify a specific config on a device or explain how an appliance is working the way it is, you could always depend on Digvijay to get things done in a timely detailed manner."
— Matthew Calhoun, Manager of US Security Operations, Northern Trust
Frequently asked questions
- Can AI replace Zero Trust architecture work?
- No. AI accelerates validation and investigation against architecture you already own. Digvijay designs and validates Zero Trust with Prisma ZTNA, Cisco SASE, and microsegmentation, then applies AI where telemetry correlation is the bottleneck.
- What proof should I ask for on AI + Zero Trust?
- Ask for measured latency or MTTD improvements tied to real platforms. Digvijay’s work includes 75% diagnostic latency reduction and 30% lower MTTD with AI-driven SASE analytics.
- Does Zero Trust AI validation work in financial services?
- Yes, when recommendations are grounded in policy, logs, and topology with an audit trail. Digvijay has delivered this style of work at Point72 and J.P. Morgan under regulated constraints.
