Outsourced Managed IT Support

IT support is an essential service for home users, businesses and organisations of all sizes. Computer Assistance IT support professionals provide technical assistance and support to users of computer systems, software, and other technology-related products. In addition we are experts at diagnosing and troubleshooting problems, providing guidance and training to users, and implementing and maintaining computer systems and networks.

Our IT support services start with our help desk which gives you access to IT experts who can answer questions and provide assistance with technical issues. This can include providing guidance on how to use specific software or hardware, troubleshooting errors and other technical problems, and assisting users with password resets and other account-related issues.

Another service we offer is to manage and maintain computer systems and networks. This can include installing and configuring hardware and software, monitoring system performance and security, and making sure that systems are up-to-date and running smoothly. Our IT support professionals will also be responsible for implementing backup and disaster recovery systems to protect data and ensure that systems can be quickly restored in the event of a failure or disaster.

In addition to providing technical support and assistance, Computer Assistance IT support professionals may also be involved in planning and implementing new technology projects. This can include evaluating and selecting new hardware and software, developing and implementing deployment and training plans, and coordinating with other teams and departments to ensure that projects are completed on time and within budget.
