IT Support in Naperville, IL for a Tech-Literate Business Community

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.

Why the I-88 Corridor Raises the Bar

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.

  • Fast, Local Response: for critical, system-down issues, we aim to respond in 15 minutes or less.

OUR NAPERVILLE STORY

Managed IT & Cybersecurity From a Family Business Serving Naperville

Ike Haislar started Computerease in 1984 to help businesses get more out of their technology without the runaround. Four decades later, that is still the job. Our Oak Brook office keeps us close to the companies we support along the I-88 corridor, from firms in downtown Naperville to offices along Diehl Road.

Today, Ryan Haislar, CISSP, leads the company as the second generation. He treats every client relationship as something the family name stands behind. For Naperville owners, that means a team that learns how your business works and plans ahead with you as you grow. For research and engineering offices with corporate IT based elsewhere, it means a local partner who backs them up instead of taking over.

What usually happens is a business goes years with IT that only shows up when something breaks. Working with us looks different. The same people support your systems over time, so they remember how things are set up and why. Small problems get fixed before they turn into a bad week, and the repeat issues start to go away.

We also give straight answers. If an upgrade can wait a year, we'll tell you. If something needs attention now, we'll explain why in plain terms and what it will cost. You get the full picture, so you can make the right call for your business.

”
“We plan every client's technology like we'll still be working together ten years from now. Along the I-88 corridor, a lot of them already have been.”

Cybersecurity for Naperville Businesses

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. It’s the same framework serious enterprise security teams rely on.

What’s Included

  • Managed SIEM: real-time log monitoring across your network, servers, and cloud accounts.
  • Managed EDR: behavior-based endpoint protection that can isolate a device the moment ransomware activity starts.
  • Managed SOC: a 24/7/365 security team watching your environment, including nights and weekends.
  • Managed Firewall and Firewall as a Service: configuration, patching, and monitoring for your network’s perimeter.
  • Managed SASE and ZTNA: secure, modern remote access built for a hybrid, tech-comfortable workforce.
  • Microsoft 365 Security Monitoring: alerts on suspicious sign-ins and mailbox forwarding rules.
  • Multi-Factor Authentication: rolled out through tools like Duo Security to block most automated attacks outright.
  • Penetration Testing: a controlled attempt to find your weaknesses before someone else does.

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.

AI Guidance for a Technically Savvy Market

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.

Co-Managed IT for Businesses With Internal IT Staff

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.

  • Coverage when your internal IT person is out or pulled into other priorities.
  • Direct access to enterprise-grade monitoring and ticketing tools.
  • Senior engineering support for a migration, office move, or infrastructure overhaul.

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.

Cloud, Phone, and Backup Essentials

  • Cloud and Microsoft 365: ongoing management of your Microsoft 365 environment, plus migrations off aging on-premise servers to Microsoft Azure.
  • VoIP Phone Systems: cloud-based phone systems that follow your team from a Naperville office to a home office or a client site.
  • Automated, Tested Backups: frequent backups, often hourly, replicated off-site and tested regularly so recovery isn’t a guess.
  • Rapid Virtualization: a failed server can be brought back online within minutes, not hours of downtime.
