Enterprise IT Support Options

Contact us to discuss your needs, goals, expectations for your upcoming project.

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.

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 enterprise 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
  • Mobile Device Management Solutions
  • Plus many more…

Contact a local account manager today to discuss the various plans and options available in our managed Services portfolio.

Managed IT Security

Meet the Changing Compliance Needs in Your Industry

Due to changing compliance requirements across industries, the demand for consistent 24/7 management and monitoring of network events, logs, and potential breaches is increasing.

The ability to stop a breach or security threat before it happens or before it becomes a larger problem can give you an advantage in the wide world of network security.

Our managed security services can provide you with the reporting, documentation, and preventive measures you need to meet ever changing compliance demands.

One of the best places to begin is with a Security Assessment that 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.

Contact a representative from our security team today to discuss the Security Assessment in further detail.
