Built for a Market That Knows the Difference Between Good IT and Good Enough.
Naperville sits along the I-88 technology and research corridor, home to a highly educated workforce and a business community that’s used to sophisticated tools, not just adequate ones. Whether you’re a decades-old professional services firm downtown or a fast-growing tech company off Diehl Road, your customers and employees expect your technology to work as well as everyone else’s around here. Computerease has supported businesses at that standard since 1984.
Computerease provides managed IT support, cybersecurity, cloud, and phone systems for businesses in Naperville, Illinois. Founded in 1984 and led today by Ryan Haislar, CISSP, the company supports healthcare practices, law firms, accounting firms, and growing tech and professional services companies throughout the I-88 corridor and western DuPage County.
Naperville isn’t a bedroom community that happens to have some offices in it. It’s part of a genuine technology and research corridor, with a workforce that includes engineers, researchers, and software professionals who know what good technology looks like because they build it for a living. That shapes expectations for every business here, whether you’re a software company or a family-owned accounting firm: slow systems, clunky remote access, or a security incident don’t just cost you time, they cost you credibility with a customer base that notices.
Computerease brings the same level of technical rigor to a 20-person professional services firm that a Naperville tech company would expect from its own engineering team, without the enterprise price tag or overhead.
A tech-literate customer base has no patience for a vendor still running on the break-fix model, waiting for something to fail before anyone looks at it. Our ConstantCare Managed IT Services program is built to catch problems 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, technically credible guidance on where AI tools genuinely add value.
An affluent, tech-forward community is an attractive target for attackers, who bet that a smaller professional services firm has weaker defenses than the tech companies around it. 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, the same framework serious enterprise security teams rely on.
Our CISSP-led team has direct experience helping healthcare practices meet HIPAA requirements, financial firms meet SEC and FINRA expectations, and growing tech companies pass vendor security reviews from larger enterprise customers.
Naperville business owners tend to ask sharper questions about AI than most, and deserve real answers, not marketing gloss. We support that with AI Readiness Assessments, employee AI training, secure Microsoft Copilot deployment, and AI Acceptable Use Policies that give your team clear, technically sound guardrails.
A number of growing Naperville companies, particularly tech and professional services firms, already have an internal IT or DevOps-adjacent person handling day-to-day support. Our co-managed model reinforces that person instead of replacing them, taking on advanced cybersecurity, 24/7 monitoring, and larger infrastructure projects.
The I-88 research corridor is home to a number of research and engineering offices for companies headquartered elsewhere, sometimes elsewhere in the U.S., sometimes in Europe or beyond. Corporate IT may set the company-wide standards and manage 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.
Our office is well positioned to reach the I-88 technology corridor and western DuPage County, with both remote and onsite support available.
Service area spans the I-88 corridor and reaches into Kendall and Will counties.

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 current provider isn’t keeping pace with how your business actually runs, or your team is dealing with recurring problems, it’s worth a second look. Our free assessment includes:
Yes. Our technicians can hold a real technical conversation, and our tools are enterprise-grade, the same caliber a larger tech company would expect, scaled appropriately for a growing business.
We aim to respond to system-down, business-critical issues in 15 minutes or less. Our help desk is staffed by live technicians, not an automated phone tree.
Yes. We regularly help growing companies scale their infrastructure and pass the vendor security reviews that come with landing larger enterprise customers.
Yes. We set up secure remote access, manage devices wherever they’re located, and make sure a team member working from home has the same reliable access as someone in the office.
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 can’t send someone to your Naperville office the same afternoon, and often doesn’t have the technical depth this market expects. We can, and we do.
