IT Support in Rosemont, IL for Businesses That Operate at the Pace of O'Hare

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.

Businesses That Never Really Stop

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.

OUR ROSEMONT STORY

Managed IT & Cybersecurity From a Family Business Serving Rosemont

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 near O'Hare, from regional sales offices to distributors and professional firms with teams on the move.

Today, Ryan Haislar, CISSP, leads the company as the second generation. He treats every client relationship as something the family name stands behind. For Rosemont owners, that means a team that learns how your business works and plans ahead with you as you grow. For regional 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. Around O'Hare, a lot of them already have been.”

Managed IT Services in Rosemont

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.

Not Sure Where to Start? Let’s Talk IT

If you’re wondering whether your current IT setup is enough – or if there’s a smarter, more secure way to operate – let’s talk. We’ll guide you through your next step.

Cybersecurity for Rosemont Businesses

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.

What’s Included

  • Managed SIEM: real-time log monitoring across your network, servers, and cloud accounts, no matter how many locations feed into it.
  • Managed EDR: behavior-based endpoint protection that can isolate a device the moment ransomware activity starts, wherever that device happens to be.
  • 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 across every site.
  • Managed SASE and ZTNA: secure, modern remote access built for employees who are frequently traveling or working from more than one location.
  • Microsoft 365 Security Monitoring: alerts on suspicious sign-ins, impossible-travel logins, and mailbox forwarding rules, the kind of business email compromise attempts that target frequently traveling staff.
  • 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 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.

Practical AI Guidance

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.

Co-Managed IT for Businesses With Internal IT Staff

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. 

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. 

  • Coverage across locations when your internal IT person can only be in one place at a time.
  • Direct access to enterprise-grade monitoring and ticketing tools.
  • Senior engineering support for a new office opening, system migration, or infrastructure overhaul.

Cloud and Phone Systems for a Team That Moves

Cloud and Microsoft 365

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.

VoIP Phone Systems

Our cloud-based phone systems follow your team between offices, client sites, and the road. Same number, same features, wherever they log in.

Backup and Disaster Recovery

  • Frequent, automated backups, often hourly, to limit how much data could ever be at risk.
  • Encrypted, off-site replication so an issue at one location doesn’t put data across the whole company at risk.
  • Rapid virtualization that can bring a failed system back online within minutes.
  • Regular recovery testing, so we know it works before you’re relying on it.
