IT Support for St. Louis Businesses on Both Sides of the River

A Local Partner for a Two-State Business Region.

St. Louis businesses don’t stop at a state line, and neither do we. Computerease supports companies across the city, the Missouri suburbs, and the Metro East communities across the Mississippi, with the same level of hands-on service wherever your office sits. We’ve been doing this since 1984, long enough to know the local internet providers, the industries that drive this region, and what it actually takes to keep a business running here.

Computerease provides managed IT support, cybersecurity, cloud, and phone systems for businesses throughout the greater St. Louis region, from its downtown office at 401 Pine Street. Founded in 1984 and led today by Ryan Haislar, CISSP, the company supports healthcare, legal, financial, and manufacturing organizations across St. Louis City and County and into the Metro East communities of southern Illinois.

Why Disaster Readiness Matters

Why Disaster Readiness Matters More Here Than Most People Realize

Severe storms, tornado warnings, and flooding along the Mississippi aren’t rare events in this region, they’re a normal part of doing business here. A lot of IT providers write a generic backup plan and call it disaster recovery. We build ours around the specific risk profile of a company that could lose power, connectivity, or a physical office with almost no warning.

That means backups that run frequently enough to actually matter, systems that can be spun back up somewhere other than your building, and a recovery plan your team has actually seen before the day they need it. It’s a different starting point than a provider parachuting in from somewhere that doesn’t deal with these risks.

OUR ST. LOUIS STORY

Managed IT & Cybersecurity From a Family Business Rooted in St. Louis

Ike Haislar started Computerease in 1984 to help local businesses get more out of their technology without the runaround. Four decades later, that is still the job. Our downtown office on Pine Street keeps us close to the companies we support, from offices downtown to plants and clinics out in the county.

Today, Ryan Haislar, CISSP, leads the company as the second generation. He treats every client relationship as something the family name stands behind. For St. Louis owners, that means a team that learns how your business works and plans ahead with you as you grow. For companies with their own IT staff, it means a 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 call that's right for your business.

"We plan every client's technology like we'll still be working together ten years from now. In St. Louis, a lot of them already have been."

Managed IT Services Across the St. Louis Region

The old model, where you call your IT guy after something breaks, doesn’t hold up for a business that can’t afford downtime. Our ConstantCare Managed IT Services plan is built to catch problems while they’re still small, not after they’ve cost you a day of productivity.

  • Continuous monitoring across your network, servers, and devices, whether they’re in your downtown office or a home setup in St. Charles.
  • Patch management that closes security gaps automatically instead of waiting for a scheduled tune-up.
  • A help desk staffed by technicians who pick up the phone, not a bot or an offshore queue.
  • vCIO planning to help you budget for technology the way you’d budget for anything else that matters to the business.
  • A single point of contact for your internet provider and software vendors, so the runaround stops being your problem.

Cybersecurity for St. Louis and Metro East Organizations

Cybersecurity for St. Louis and Metro East Organizations

From financial firms and healthcare providers to manufacturers, businesses throughout St. Louis and the Metro East have sensitive information and critical systems to protect. Led by a CISSP-certified security expert, Computerease helps organizations evaluate their cybersecurity risks and determine which protections make the most sense for their business. Our cybersecurity services are available separately from Managed IT and can be customized based on each organization’s security needs, using the Center for Internet Security (CIS) Critical Security Controls as a guide.

Core Protections

  • Managed SIEM: continuous log analysis across your firewalls, servers, and cloud accounts.
  • Managed EDR: behavior-based endpoint protection that can isolate a device the moment something looks wrong.
  • Managed SOC: a 24/7/365 security team watching for activity that shouldn’t be there, including the middle of the night.
  • Managed Firewall and Firewall as a Service: your network’s front door, configured and monitored on your behalf.
  • Managed SASE and ZTNA: modern, secure remote access built for a hybrid team spread across two states.
  • Microsoft 365 Security Monitoring: watching for compromised logins and suspicious mailbox rules.
  • Multi-Factor Authentication: deployed through tools like Duo Security to block most automated attacks outright.
  • Penetration Testing: a controlled attempt to break in, so the gap gets found by us first.

For regulated and defense-adjacent organizations, our CISSP-led team supports HIPAA compliance for healthcare practices, SEC and FINRA alignment for financial firms, and CMMC readiness for manufacturers and contractors working near Scott AFB.

AI Guidance Without the Hype

Most business owners we talk to are interested in AI and wary of it in equal measure. We help make that manageable with AI Readiness Assessments, employee AI training, secure Microsoft Copilot deployment, and AI Acceptable Use Policies that give your team clear boundaries instead of a policy vacuum.

Co-Managed IT for Businesses With Their Own IT Staff

A lot of mid-sized St. Louis companies have an internal IT person who’s stretched too thin to also own cybersecurity, infrastructure, and strategic planning. Our co-managed model fills that gap without replacing anyone. Your team keeps handling day-to-day support, and we take on the heavier technical lifting.

  • Coverage when your IT person is on vacation, out sick, or buried in a project.
  • Access to enterprise-grade monitoring and ticketing tools your team can use directly.
  • Senior engineering support for a server migration, office move, or cloud transition.

Cloud and Communication Tools Built for a Hybrid Region

Cloud and Microsoft 365

We manage your Microsoft 365 environment day to day, not just at rollout, and we handle migrations off an aging on-site server to Microsoft Azure when it’s time to stop paying to keep old hardware alive.

VoIP Phone Systems

Our cloud-based phone systems move with your team, whether they’re in the Pine Street office, working from home in O’Fallon, or on the road. Same number, same features, wherever they log in.

Backup and Disaster Recovery Built for This Region

  • Frequent, automated backups, often as often as every hour, to keep the amount of data at risk small.
  • Off-site, encrypted replication so a compromised office doesn’t mean compromised data.
  • Rapid virtualization that can bring a failed server back online in minutes, not days.
  • Regular recovery testing, because a backup nobody has tested is just a guess.

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 is slow to respond, your team is dealing with the same problems on repeat, or you’re not confident your backups would hold up in a real disaster, it’s worth a second opinion. The assessment includes:

  • A full audit of your current infrastructure and security posture.
  • A scan for vulnerabilities, misconfigurations, and compliance gaps.
  • A check on whether your backups would actually recover, not just whether they run.
  • A plain-English report with next steps, no sales pressure attached.
