IT Support & Managed Services in Naperville, IL
Headquartered on Park Street since 2010 — not a remote call center in another state.
ExColo is based at 1755 Park Street, Suite 200, right here in Naperville. When a Naperville business calls us, they're calling a neighbor, not a national help desk reading from a script. That matters for two practical reasons: we can be on-site the same day for anything that needs hands on a switch or a server rack, and we already understand the mix of businesses that make up this market — from professional offices along the Route 59 corridor to healthcare practices and manufacturers throughout DuPage County.
What Naperville businesses come to us for
Managed IT Support
Ongoing monitoring, help desk, and maintenance for offices that don't have (or don't want) a full-time internal IT team.
Cybersecurity & Network Security
Zero Trust architecture, Cisco ISE deployment, and security evaluations for businesses that handle sensitive client or patient data.
Network Design & Integration
New office build-outs, expansions, and network redesigns for growing Naperville companies.
Cloud & Hosting
Migration to private, public, or hybrid cloud, plus managed hosting for companies ready to move off aging on-premise servers.
Why local matters for IT support
Most IT problems can be solved remotely, and we do that constantly. But the ones that can't — a failed switch, a downed access point, a physical server that won't boot — are exactly the ones that turn into a full day of lost productivity when your IT provider has to fly someone in or mail a technician from the next county over. Being five minutes from most of downtown Naperville means that when it's a same-day, on-site problem, it's a same-day, on-site fix.

Frequently Asked Questions
It depends on headcount, environment complexity, and whether you need full managed services or a specific engagement like a security evaluation or network redesign. We scope pricing after understanding your environment on a free, no-obligation call — not from a generic per-seat rate card that doesn't reflect what you actually need.
Our office is in Naperville, and we serve businesses across DuPage County including Aurora, Lisle, Wheaton, and Downers Grove, plus the broader Chicago metro for remote-eligible work. Same-day on-site response is easiest within about a 20-minute radius of our Park Street office.
Both, and we don't treat them as separate disciplines. Every managed IT engagement includes security fundamentals — patching, monitoring, access control — and for organizations that need it, we go deeper with Zero Trust architecture, Cisco ISE deployment, and formal network security evaluations.
For businesses in Naperville and the immediate surrounding area, same-day on-site response is standard for issues that genuinely need hands on hardware. Most day-to-day issues are resolved remotely faster than a truck roll would even get someone there.
No obligation — talk to an engineer, not a salesperson.
