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.

Quick Answer
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 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.

What St. Louis Businesses Get With Computerease
- CISSP-Led Security: every security strategy is built and signed off by a Certified Information Systems Security Professional.
- Family-Owned Since 1984: a second-generation, locally accountable business, not a franchise or a private-equity rollup.
- One-Year Start, Then Month-to-Month: clients continue past year one because the service earns it, not because a contract requires it.
- Same-Day Onsite When It’s Needed: a technician who can actually get to your building, not one flying in from another state.
- Nationally Recognized: named to the Inc. 5000 and the CRN MSP 500.
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.
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 St. Louis and Metro East Organizations
This region has a bigger target on its back than most people assume: a dense concentration of financial firms, healthcare systems, and defense-adjacent manufacturers, several of them within a short drive of Scott Air Force Base on the Illinois side. Computerease builds security into every plan rather than selling it as an upsell, using the Center for Internet Security (CIS) Critical Security Controls as the foundation.
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.
Industries We Support
Every industry has unique challenges. A law firm in downtown St. Louis has different needs than a manufacturing plant in Granite City or a medical clinic in Ballwin. We don’t believe in cookie-cutter solutions. We tailor our IT support to your specific vertical.
IT Services for Healthcare & Medical Practices
From independent practices to multi-location clinics, we keep EHR systems running, networks HIPAA-aligned, and patient data secure across the St. Louis healthcare corridor.
IT Solutions for Financial & Accounting Firms
Trust is the product in this industry. We help CPA firms, wealth managers, and community banks meet SEC and FINRA expectations with security built for regulated data.
Managed IT for Manufacturing & Logistics
This region runs on manufacturing and distribution. We support ERP systems, shop-floor connectivity, and disaster recovery plans built to limit the cost of an outage.
Engineering & Construction IT Support
We advise on technology for both AutoCAD workstations in the office and rugged laptops in the field, backed by nearly 40 years supporting firms in this industry.
IT Support for St. Louis Law Firms
We support case management software, secure document handling, and remote access for attorneys who bill by the hour and can't afford downtime.
Small & Medium Business IT Support
A reliable, responsive IT partner can end a cycle of recurring problems for a growing business.

Computerease vs. Large National MSPs
| Â | Computerease | Large National MSPs |
When you call | A St. Louis technician who already knows your network | A ticket enters a national queue |
Onsite reality | A tech can be at your office the same day | Onsite visits often require scheduling days out |
Security ownership | Built and overseen by a CISSP, not outsourced further | Security is often a subcontracted add-on |
Contract length | One year to start, month-to-month after that | Multi-year terms are the default |
Who’s accountable | A family name that’s been in this market since 1984 | A brand managed by a distant corporate office |
Storm and outage readiness | Backup and recovery built around real regional risk | Generic backup plans not tuned to your region |

Bob Barenholtz
St. Louis TagDan 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.

Questions St. Louis Businesses Ask Us
We aim to respond to system-down, business-critical issues in 15 minutes or less. Our local help desk is staffed by real technicians, not an automated phone tree.
Yes. We regularly support Metro East communities including Belleville, Edwardsville, O’Fallon, and Fairview Heights, alongside our Missouri client base.
Yes. Whether it’s a cyber insurance renewal, a HIPAA audit, or CMMC documentation for a defense-adjacent contractor, our CISSP-led team can guide the process and remediate gaps.
Yes. Whether it’s a cyber insurance questionnaire, a HIPAA audit, or CMMC certification, our CISSP-led team has the expertise to guide you through the process, remediate gaps, and provide the necessary documentation.
Your backups are replicated to secure off-site data centers, so a damaged or powerless office doesn’t mean lost data. We can virtualize a failed server in minutes if needed.
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 Creve Coeur or O’Fallon office the same afternoon. We can. We’re also a neighbor with a stake in this region’s businesses succeeding, not a branch office managed from somewhere else.
