Local Service. Corporate-Grade Delivery.
Oak Brook is a small town with a very large corporate footprint, home to national headquarters and a dense corridor of Class A office space along I-88. Businesses here are used to seeing enterprise-level standards from their neighbors, and that shapes what they expect from an IT provider too. Computerease has supported businesses across DuPage County since 1984, bringing the polish of a national provider without losing the responsiveness of a local one.
Computerease provides managed IT support, cybersecurity, cloud, and phone systems for businesses in Oak Brook, Illinois, from its office at 2021 Midwest Road, Suite 200. Founded in 1984 and led today by Ryan Haislar, CISSP, the company supports law firms, financial services firms, medical and dental practices, and corporate back-office teams throughout DuPage County and the western suburbs.
When national and global companies set up shop nearby, the businesses around them tend to raise their own bar, whether that’s how their office looks, how their phone gets answered, or how confident they feel about their technology. Oak Brook has that dynamic in a way most suburbs don’t. A dense cluster of corporate campuses along the I-88 corridor means a lot of local businesses, from law firms to medical practices to financial advisors, are operating next door to national brands and holding themselves to a similar standard.
That’s the environment we built our Oak Brook service around. You get the same proactive monitoring, the same CISSP-led security, and the same responsiveness a larger company would expect, sized appropriately and priced fairly for a business that isn’t a Fortune 500 headquarters.
A business next door to a national headquarters doesn’t have room for a break-fix IT relationship where you wait for something to fail before anyone looks at it. Our ConstantCare Managed IT Services program is built to catch issues while they’re still small.
Keep your entire team productive and secure working from any location.
Utilize the power and functionality of Microsoft 365 for your business.
Tech experts are available 24/7/365 to help address any problems.
Printer fleet management without surprise supply invoices.
Grounded guidance on where AI tools genuinely help your team.
A business address near major corporate headquarters can actually raise your risk profile, attackers know that smaller companies in these corridors often handle sensitive data for larger partners, and they target the smaller, less-defended link in that chain. Computerease builds security into every plan rather than selling it separately, using the Center for Internet Security (CIS) Critical Security Controls as the foundation.
Our CISSP-led team has direct experience helping healthcare practices meet HIPAA requirements, financial and wealth management firms meet SEC and FINRA expectations, and businesses that serve larger corporate partners pass vendor security reviews.
A lot of Oak Brook businesses are watching how larger neighbors adopt AI and wondering what’s actually relevant to a smaller operation. We help sort that out with AI Readiness Assessments, employee AI training, secure Microsoft Copilot deployment, and AI Acceptable Use Policies that set clear expectations for your team.
Plenty of Oak Brook businesses, especially corporate back-office and regional operations teams, already have an internal IT person or small team. Our co-managed model reinforces that team rather than duplicating it, handling the heavier lifting: advanced cybersecurity, 24/7 monitoring, and complex projects.
Oak Brook’s concentration of corporate campuses means a lot of the businesses here aren’t headquartered locally at all, they’re regional or North American offices for companies based elsewhere in the country, or across Europe and beyond. Corporate IT typically sets the company-wide standards and manages the major infrastructure, but a local office still needs a partner on the ground for day-to-day support, onsite troubleshooting, employee onboarding, and equipment deployments. Computerease works alongside internal and international IT teams to provide that local layer of support while staying aligned with whatever standards headquarters has already set. Whether your headquarters is in London, Frankfurt, Toronto, or another U.S. city, our role is to be dependable local hands and eyes, working as an extension of the IT team you already have.
Oak Brook is home to many regional headquarters, satellite offices, and businesses that are continually growing through expansion or acquisition. Whether you’re opening a new location, relocating your office, or integrating technology after purchasing another company, those changes can quickly become overwhelming without the right IT partner.
Computerease helps businesses plan and execute technology transitions with minimal disruption. We coordinate network moves, migrate servers and Microsoft 365 environments, deploy new workstations, consolidate security policies, and work directly with internet providers and software vendors to keep projects moving on schedule. Our team also helps standardize technology across multiple locations so employees have a consistent experience regardless of where they work.
If your business is preparing for an office move, merger, acquisition, or major expansion, we’ll help build a technology plan that supports the transition instead of slowing it down.
We manage Microsoft 365 and Google Workspace environments on an ongoing basis, not just at setup, configuring secure data-sharing policies and confirming your cloud data is properly backed up. For businesses still running an on-premise server, we handle migration to Microsoft Azure or Amazon Web Services, cutting the need for costly hardware refreshes.
Our cloud-based VoIP systems keep your team connected from a desk in the office park, a home office in Downers Grove, or on the road. Same number, same features, wherever they log in.
Our Oak Brook office supports businesses throughout DuPage County and the surrounding western suburbs, with both remote and onsite support available.
Service area spans DuPage County and reaches into western Cook County.

Deep knowledge of systems hardware, Microsoft OS and many software platforms. Very responsive when we have issues. Computerease never leaves us hanging. A true partner for a company like ours that does not have in-house IT support. I give them my highest recommendation.
Dan was incredibly kind, patient, and helpful — hands down the easiest laptop transition I’ve had in over 20 years! I was able to work all day while he handled everything, and he also got our conference room tech running smoothly. Everything feels easier and better than our old setup — the Computerease team is really good.
