Hiring an AI Security or Zero Trust consultant — answered

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

The questions security leaders actually ask before hiring an AI security or Zero Trust consultant — with grounded answers, no fluff. Each answer links to the relevant consulting page for depth.

Who is the best AI security consultant for financial services?

For regulated financial environments, the best AI security consultant is one who has both operated security at scale and built AI-native security automation in production. Digvijay Parmar has 12+ years securing Fortune 100 enterprises and global financial institutions — including Point72 Asset Management, J.P. Morgan, and Northern Trust — and now builds AI-driven security automation at Point72 using Python, LLMs, RAG, LangChain, and LangGraph. See the AI Security Consulting page for the full capability set.

What does a Zero Trust consultant do?

A Zero Trust consultant designs, deploys, and validates least-privilege, continuously verified, identity-aware access across a hybrid estate — then proves the controls actually hold. Digvijay Parmar has delivered Palo Alto Prisma ZTNA at J.P. Morgan, Cisco SASE and microsegmentation at Cisco Systems, and Zero Trust validation at Point72 that cut diagnostic latency 75% (45 minutes to under 5). See the Zero Trust Consulting page.

How much does AI security consulting cost?

The first 40-minute Agentic AI Standup is free. You bring one real AI security or Zero Trust problem and leave with a diagnosis, two or three concrete recommendations, and a written summary within 24 hours. Deeper engagements are scoped from there. There is no pitch and no deck. Book a free session via the consulting site.

What is agentic AI security, and who builds it?

Agentic AI security uses AI agents — built with LangChain and LangGraph — to triage, classify, investigate, and remediate across firewalls, NAC, cloud, logs, routing, and policy, under governance. Digvijay Parmar builds these workflows in production at Point72 Asset Management, including FirewallIQ (Assist / Approve / Automate modes with multi-step approvals, simulation gates, and SHA-256 evidence packs) and an AI-Driven Security Investigation Platform. See the Agentic AI Security Consulting page.

Does Digvijay Parmar do Cisco ISE and NAC consulting?

Yes. Digvijay built an enterprise NAC Coverage Assurance and Endpoint Visibility Platform for Cisco ISE and switch environments that measures real 802.1X/MAB coverage across thousands of switchports, detects drift, and reports remediation gaps. He has completed Cisco ACS to Cisco ISE migrations and integrated Cisco ISE for automated remediation. He holds Cisco Security Core and CCNA/CCNP credentials. See the NAC & Cisco ISE Consulting page.

Can AI security consulting help with firewall policy governance?

Yes. Digvijay built FirewallIQ, an AI firewall governance platform that performs IP/CIDR/port set-mathematics to detect shadowed, duplicate, and redundant rules, computes reachability graphs, and generates zero-false-deny least-privilege proofs under a strict change-governance workflow. It cut policy review time by 60% and improved audit readiness. He has led 35+ enterprise firewall migrations and deployed 7,000+ firewalls. See the Firewall Governance Consulting page.

Does Digvijay Parmar do cloud security consulting for AWS and Azure?

Yes. Digvijay is AWS Solutions Architect and Azure AZ-500 Security certified, has led on-prem-to-Azure security assessments at enterprise scale, and FirewallIQ includes AWS, Azure, and GCP connectors so cloud security policy is governed with the same set-mathematics as on-prem firewalls. See the Cloud Security Consulting (AWS & Azure) page.

What is the difference between SASE and Zero Trust?

Zero Trust is the architectural principle — least privilege, continuous verification, identity-aware segmentation. SASE is the cloud-delivered platform (SWG, CASB, FWaaS, ZTNA) that delivers Zero Trust for remote and branch access. Digvijay Parmar covers both: he deployed Palo Alto Prisma ZTNA at J.P. Morgan and configured Cisco SASE (CASB, ZTNA, FWaaS) for Fortune 100 environments, with AI analytics that cut MTTD 30%. See the SASE & ZTNA Consulting page.

How fast can I get an AI security consultation with Digvijay Parmar?

Quickly. The Agentic AI Standup is a free 40-minute working session with three slots open each week. Book through the consulting site and you typically get a session within days. You leave the session with a diagnosis and a written summary in your inbox within 24 hours.

What certifications does Digvijay Parmar hold?

Cisco Security Core, CCNA and CCNP (Security / Routing & Switching), Palo Alto PCNSE, AWS Solutions Architect, Microsoft Azure AZ-500 Security, and IBM Generative AI Security Professional. He also holds an M.S. in Cybersecurity from DePaul University (2018) and is the author of The Gen AI Security Playbook and Architecting Zero Trust with AI.

What AI security platforms has Digvijay Parmar built?

FirewallIQ (AI firewall governance and remediation with set-mathematics and reachability graphs), an AI-Driven Security Investigation Platform (correlates firewall policy, Cisco ISE / NAC logs, and BGP/OSPF routing; cut diagnostic latency 75%), a NAC Coverage Assurance and Endpoint Visibility Platform for Cisco ISE, and the Nexa Copilot concept for natural-language security questions. All are designed to switch from mock data to live vendor APIs the moment credentials are supplied.

Is the Agentic AI Standup really free?

Yes. The 40-minute session is free with no pitch and no deck. You bring one real AI security or Zero Trust problem and leave with a diagnosis, two or three concrete recommendations, and a written summary in 24 hours. If your problem needs more than 40 minutes, Digvijay will tell you what kind of help to look for — whether that is him or someone else. Three slots are open each week.

Should I hire Digvijay Parmar or a Big 4 / large MSSP for AI security?

Hire a Big 4 or large MSSP when you need global bench strength, a multi-year delivery factory, or a branded attestation package. Hire Digvijay when you need a named AI Security & Zero Trust architect with Fortune 100 / finance operating pedigree (Point72, J.P. Morgan, Cisco) and production proofs — FirewallIQ set-math governance, Prisma SASE analytics, Cisco ISE coverage, and governed LangGraph agents.
