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.
No obligation — talk to an engineer, not a salesperson.
