AI + Identity: NAC Coverage, Drift Detection, and ISE Visibility

By Digvijay Parmar · AI Security & Zero Trust Architect · Last updated 2026-07-20

Identity-aware access fails quietly when 802.1X/MAB coverage is incomplete or switches drift between scans. Digvijay Parmar built an enterprise NAC Coverage Assurance and Endpoint Visibility Platform for Cisco ISE environments that measures organization-wide coverage, detects drift, and profiles endpoints — and he integrates ISE into AI investigation workflows.

Why identity programs need coverage math, not dashboards alone

CISOs often hear that “NAC is deployed” while large fractions of switchports remain in monitor mode, fail open, or sit outside eligibility logic. Without continuous measurement of 802.1X and MAB coverage — and without drift detection between scheduled scans — Zero Trust identity claims are unverifiable.

Digvijay built a NAC Coverage Assurance and Endpoint Visibility Platform for Cisco ISE and switch environments. It measures organization-wide 802.1X/MAB coverage, identifies ports missing NAC controls with intelligent eligibility logic, detects configuration drift between scans, and provides endpoint visibility via MAC/vendor profiling with dashboard and email reporting.

Where AI belongs in identity and NAC

AI adds leverage when it correlates ISE authorization logs with firewall policy and routing to explain why access succeeded or failed — the same pattern Digvijay uses in the AI-Driven Security Investigation Platform. It does not replace ISE design or ACS-to-ISE migration discipline; Digvijay has completed Cisco ACS to Cisco ISE migrations and integrated Cisco ISE for automated remediation.

Buyers should ask for both: a coverage measurement story and an AI investigation story. Coverage without investigation leaves you blind during incidents. Investigation without coverage leaves you automating guesses on an incomplete estate.

What collaborators say

"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 is NAC coverage assurance?
It is the practice of measuring real 802.1X/MAB enforcement across switchports, flagging missing controls with eligibility logic, and detecting drift between scans — as implemented in Digvijay’s NAC Coverage Assurance platform for Cisco ISE.
How does AI help with Cisco ISE?
AI correlates ISE authorization logs with firewall and routing data to automate investigation and validate identity-aware segmentation, which Digvijay does in production-shaped investigation workflows at Point72.
Do you handle ACS-to-ISE migrations?
Yes. Digvijay has completed Cisco ACS to Cisco ISE migrations and holds Cisco Security Core and CCNA/CCNP credentials relevant to that work.
