Cybersecurity Consulting for Chicago Businesses
Zero Trust, network microsegmentation, and identity security — built for how Chicago companies actually operate.
Chicago's business mix — healthcare systems, financial and professional services firms, manufacturers, logistics operators moving through the region's rail and highway corridors — means there's no single cybersecurity playbook that fits everyone. A healthcare group worried about patient data needs a very different security posture than a logistics company worried about operational uptime. ExColo has worked across both, from our base in the western suburbs, since 2010.
Where we focus
Zero Trust Architecture
Identity-first security design that assumes breach and verifies every request — not perimeter security that stops at the firewall.
Network Microsegmentation
Limiting lateral movement so a single compromised device can't become a company-wide breach.
Cisco ISE Deployment
Identity Services Engine design and deployment for organizations standardizing on Cisco's security stack.
Security Evaluations & Audits
Hands-on assessment of your actual infrastructure — not just a vulnerability scanner report.
A regional firm, not a call center
We're not a national MSP dispatching whichever technician is available that week. Engagements are handled by engineers who've been doing Cisco ISE and Zero Trust work in this market for years — the same people writing our security blog are the ones showing up to your assessment. For Chicago-area organizations that need a security partner who understands both the technology and the regulatory pressure (NIS2-aligned frameworks, healthcare compliance, financial services scrutiny), that continuity is the point.

Frequently Asked Questions
We're headquartered in Naperville, IL and have worked with Chicago-area organizations since 2010. Engagements are handled by the same engineers you'd talk to on a first call — not a rotating pool of subcontractors.
Yes. We've supported healthcare organizations on HIPAA-aligned network access control and financial/professional services firms on compliance-driven security evaluations. Our Cisco ISE deployments in particular are built with audit documentation in mind.
It depends entirely on scope — a network security evaluation is a different investment than an ongoing Zero Trust rollout. We start with a free, no-obligation assessment call to understand your environment before quoting anything.
Our Naperville page covers day-to-day managed IT support and help desk services. This page focuses specifically on cybersecurity consulting — Zero Trust, microsegmentation, ISE, and security evaluations — for the broader Chicago metro, whether or not you use us for general IT support too.
No obligation — talk to an engineer, not a salesperson.
