IT Managed Services

Cloud Services / Cloud Backup / Cloud Base Exchange
Many businesses have turned to cloud services for data security and integrity. Companies can store critical business data in a cloud storage environment and have access to that information anytime, anywhere, even after a catastrophic loss of equipment due to fire, flood, theft, power failure or a multitude of other threats. Cloud computing solutions such as email, cloud backup, or a cloud based server strategy is an excellent part of any business continuity or disaster recovery strategy.

Server & Workstation Monitoring
Remote Management such as server and workstation monitoring provides a pro-active approach to IT support. Rather than simply monitoring servers, our system offers the capability of antivirus and allows IT Managers the ability to monitor RAID arrays, remote offices, ISP connections, bandwidth usage, websites and more. In short, we help you monitor the key parts of your whole network that cause the most grief – and alert you proactively.

Experience is what counts when it comes to IT consulting. The experienced staff at CMS can assist your organization with a wide variety of IT related projects. With our expertise you can be rest assured that your project will be completed on time and on budget.

Remote support allows for an immediate response that is both efficient and effective. Our remote tools also allow us to transfer files, view resources, analyze error logs that provide the information for a fast and successful support session that will minimize downtime and keep workers productive.
