Co-managed IT Support

In-house IT is common among larger enterprise level businesses. With in-house IT staff, you can deal with emergencies when they arise and technicians are under your own direction.

But due to time constraints and the rapid pace at which technology changes, at times it makes sense to partner with an outsourced IT provider.

Ontech is available to fill in the gap and work in tandem with your internal IT staff. We can be involved as little or as much as you’d like.

We build the project and scope around your internal IT team and we are available to assist with special projects in any capacity you see fit.

Whether you need to supplement in-house IT support, get assistance with a specialized IT solution or better utilize managed IT and security services in your business, a quick 10 minute call is all it takes to see if Ontech is a good fit.

Enterprise Managed Services

Managed services allow businesses to have consistent and predictable monthly IT costs, while at the same time, exceptional service through our Remote Monitoring & Management (RMM) tools.

Some of our clients rely completely on our NOC and managed service model. Others combine the benefits of our managed services along with their local onsite technicians to incorporate a hybrid service approach to manage their IT needs.

Managed services and the tools provided have allowed Ontech to support clients not only in SE Wisconsin, but also across the globe.  As your business leans more toward mobility and data is stored in various locations, our managed service offerings allow us to effectively provide the level of support that your business demands.

Our service offerings include:

  • 24×7 coverage and support on all devices of your network
  • Global Help Desk: 24×7, Business Hours, and off hours options available

The information gathered and reported in a Security Assessment can provide you with the tools and up to date information to protect your network from a security breach – whether it be internal or external.   After a Security Assessment, you can comfortably prioritize the remedy of security threats, determine a budget, create a plan, and take action.
