Preparing Your Business for AI Starts With Stable IT
Artificial intelligence is changing how businesses operate, but AI is only as effective as the technology behind it. Microsoft Copilot and other AI tools rely on secure Microsoft 365 environments, well-managed devices, reliable cloud infrastructure, and strong identity protection to deliver accurate, secure results.
Managed IT Services provide that foundation. We help businesses modernize their technology, strengthen cybersecurity, organize Microsoft 365, and build the infrastructure needed to adopt AI with confidence. Whether you’re exploring AI for the first time or expanding its use across your organization, we help ensure your technology is ready before you move forward.

Do you have a sneaking suspicion that your current IT guy doesn’t have a handle on things? Our free, 57 point free IT Assessment will reveal and show you how to eliminate all your IT problems and never pay for unnecessary IT expenses again.

Our Process
- Free IT Assessment: a 57-point, no-obligation review of your network, security, and backups.

- Monitor and Support: certified engineers watch your network 24/7 and respond when something needs attention.
- Review: regular check-ins so your support keeps pace as your business changes.
Strategic Technology Planning
Good Managed IT Services are about more than fixing computers when something breaks. They help you make better technology decisions before problems happen.
Our team works with business owners and leadership teams to develop practical technology roadmaps that align with business goals. That includes planning equipment replacement cycles, budgeting for future investments, strengthening cybersecurity, preparing for AI adoption, supporting business growth, and helping technology keep pace as your organization changes.
Rather than reacting to problems, we help you make informed technology decisions that reduce risk, improve productivity, and support long-term success.
Additional Technology Services
A Technology Plan That Grows With You
The IT support that fits a 12-person office is not the same support a 40-person office needs. As you add employees, open a new location, or bring on new software, your support needs change with you, and a plan that was right a year ago can quietly stop being enough.
We review your support plan on a regular basis rather than setting it once and leaving it alone, so decisions about staffing, budget, and new locations get made with current information instead of a plan built for the business you used to be.

Questions Businesses Ask Us
Founded in 1984 by Dennis (Ike) Haislar, Computerease is a Managed Services Provider serving Greater St. Louis and all of Illinois, now led by his son Ryan Haislar, CISSP.
An outsourced company that remotely manages a business’s IT infrastructure and end-user systems, usually for one flat monthly rate.
Keeping up with security threats, industry compliance, and the right hardware for your business takes real time. A Managed Services Provider handles that so you do not have to, with your infrastructure protected around the clock.
We offer co-managed services as a supplement to your existing staff, combining with your team’s skills rather than replacing them.
The best customer service still happens face-to-face. While most issues can be handled remotely, a local team can be on-site when a personal touch matters.
Yes. Every call is answered by a real person, not a voicemail queue.
Most technology problems can be handled remotely, often within minutes of your call. For issues that need a hands-on visit, local technicians respond quickly.
Clients start with a one-year initial agreement. After that, most continue month to month because the relationship holds up on its own.
Most clients come to us because they’re frustrated with slow response times, recurring technology problems, inconsistent communication, or cybersecurity concerns. Others are looking for a more strategic IT partner after their previous provider was acquired by a larger company or stopped providing the personal service they expected. We focus on responsive support, practical technology planning, and long-term relationships built on trust.
Pricing is built around the size of your business and what you need supported. Start with a free IT Assessment and we will give you a straight answer on cost.
