Built for Companies That Rarely Sit Still.
Rosemont sits at one of the busiest crossroads in the country, and the businesses based here reflect that: professional service firms with clients nationwide, distributors and logistics operations, regional sales offices, and companies with employees who are just as likely to be at an airport gate as at a desk. Computerease has supported businesses like these since 1984, with IT built around travel, remote work, and more than one location, not a single fixed office.
Computerease provides managed IT support, cybersecurity, cloud, and phone systems for businesses in Rosemont, Illinois. Founded in 1984 and led today by Ryan Haislar, CISSP, the company supports professional service firms, healthcare organizations, manufacturers, and distribution and logistics companies throughout the O’Hare-adjacent business corridor.
Being minutes from O’Hare shapes the kind of businesses that set up here, and it’s not what people usually assume. Rosemont is home to a meaningful concentration of regional sales offices, distribution and logistics operations, and professional service firms who chose this location specifically because their people and their shipments move through here constantly. Add in companies running multiple offices and employees who split time between the road and a laptop, and you get a business community built around motion, not a fixed 9-to-5 footprint.
That’s the environment Computerease actually builds for: secure access that works the same whether someone is in the office, on a layover, or working from a second location, and systems that don’t assume everyone is sitting at the same desk every day.
A business with employees moving between offices, client sites, and airports can’t afford a support model built around someone being at their desk. Our ConstantCare Managed IT Services program is built to catch problems before they interrupt work that doesn’t happen on a fixed schedule.
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.

grounded guidance on where AI tools genuinely help a growing, multi-location business.
Businesses with traveling employees, multiple locations, and clients nationwide face a security picture that’s different from a single-office company: more logins from more places, more vendor relationships, and more opportunities for an attacker to slip in through a compromised account rather than a compromised building. Computerease builds security into every plan instead of selling it as an upsell, using the Center for Internet Security (CIS) Critical Security Controls as the foundation.
Our CISSP-led team has direct experience helping businesses respond to vendor security questionnaires from larger partners, protect identity and access across multiple offices, and secure a remote or traveling workforce without slowing anyone down.

Businesses near O’Hare are increasingly adopting Microsoft Copilot and other AI tools to improve productivity, customer service, document management, and internal operations. We help organizations evaluate AI safely, train employees, create AI Acceptable Use Policies, and deploy AI without introducing unnecessary cybersecurity risk.
That includes AI Readiness Assessments, employee AI training, secure Microsoft Copilot deployment, and AI Acceptable Use Policies tailored to how your team actually works.
Regional offices and multi-location companies based in Rosemont often already have an internal IT person managing one site while trying to keep an eye on others. Our co-managed model reinforces that person instead of replacing them, taking on advanced cybersecurity, 24/7 monitoring, and the coordination that multiple locations require.
Many businesses in the Rosemont and greater Chicago area are regional offices for companies headquartered elsewhere in the United States or internationally, particularly across Europe. While corporate IT may establish company-wide standards and manage major infrastructure, local offices still need a trusted technology partner to handle day-to-day support, onsite troubleshooting, employee onboarding, equipment deployments, and coordination with headquarters. Computerease works alongside internal IT teams around the world, providing responsive local support while helping maintain the consistency and security standards established by the parent organization.Â
Whether your headquarters is in London, Frankfurt, Toronto, or another U.S. city, our role is to provide dependable local support while working as an extension of your existing IT team.Â
We manage Microsoft 365 environments on an ongoing basis, not just at setup, and handle migrations off an aging on-premise server to Microsoft Azure when it’s time to retire that hardware, giving every location and every traveling employee the same reliable access.
Our cloud-based phone systems follow your team between offices, client sites, and the road. Same number, same features, wherever they log in.
Our office is well positioned to reach the O’Hare-adjacent business corridor, with both remote and onsite support available.
Service area spans northeast Cook County, connecting with our Elk Grove Village and Oak Brook coverage nearby.

I have been with Computerease for many years. They have a great team of I.T. techs, whether it is on the phone or coming to my office. They are fast and efficient.
We are a small business and have been a Computerease client for years. I highly recommend their services for large and small firms. Always extremely efficient with their response times and very knowledgeable on all things computers/systems!
I have to say, these guys and girls are the BEST! They are there for every question and issue, always with the perfect resolution. We reach out to them often just exploring options with our systems. Computerease always makes our lives easier! We love them!!
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.

If your business runs across more than one location, relies on employees who travel, or your team is dealing with recurring problems, it’s worth a second look. Our free assessment includes:
Yes. We regularly support multi-location businesses and regional offices, with consistent monitoring, security, and support across every site, not just the one nearest to us.
Yes. We build secure remote access around employees who aren’t always at the same desk, including protections against the kind of account compromise attempts that specifically target traveling staff.
We aim to respond to system-down, business-critical issues in 15 minutes or less.
Yes. Our CISSP-led team regularly helps businesses respond to vendor security questionnaires and close the gaps they reveal.
Clients start with a one-year initial agreement. After that, most continue month to month because the relationship holds up on its own.
A national call center often applies a single-office assumption to every account. We build for businesses that operate across locations and time zones, because that’s who’s actually based here.
