AI-Assisted Cisco ISE and NAC Operations at Scale
Cisco ISE and NAC fail operationally when coverage is unknown and drift is invisible. Digvijay Parmar built NAC coverage assurance and endpoint visibility for Cisco ISE, completed ACS-to-ISE migrations, and correlates ISE logs into AI investigation workflows used to validate Zero Trust — with 12+ years of Cisco-heavy security engineering.
Operating ISE at estate scale
Large Cisco estates drown in exceptions: monitor-mode ports, failed authentications, and configuration drift after weekend changes. Digvijay’s NAC Coverage Assurance and Endpoint Visibility Platform measures real 802.1X/MAB coverage across thousands of switchports, applies eligibility logic for missing controls, detects drift between scheduled scans, and reports via dashboard and email.
That operational backbone is what makes AI useful. Without coverage truth, AI remediation suggestions guess. With coverage truth, AI can prioritize the ports and identity paths that actually matter.
AI on top of ISE telemetry
Digvijay integrates Cisco ISE for automated remediation patterns and feeds ISE authorization logs into AI-driven investigation that also reads firewall policy and routing — reducing diagnostic latency by 75% on complex investigations in his Point72 work.
He has also led Cisco ACS to Cisco ISE migrations and holds Cisco Security Core plus CCNA/CCNP credentials. Buyers should prefer operators who have migrated and run ISE, not only trained on it.

Frequently asked questions
- Can AI replace Cisco ISE design?
- No. AI assists coverage measurement, drift detection, and investigation. Digvijay still designs and migrates ISE/NAC as an operator, then layers AI on verified telemetry.
- What scale of NAC estates has Digvijay worked?
- His NAC Coverage Assurance platform targets organization-wide measurement across thousands of switchports with eligibility logic and drift detection between scans.
- Do you support ACS-to-ISE projects?
- Yes. Digvijay has completed Cisco ACS to Cisco ISE migrations as part of NAC consulting engagements.
