What We Do
Our world is increasing in complexity. Organizations are changing at an ever-increasing rate. Businesses face an uphill battle to adapt to change and to stay ahead of the competition. At the same time, our cities are increasingly becoming more populated; and with this growth, issues such as demand on resources and public safety become a key focus for government and civic leaders. Today, more than any other time, you need a technology partner that has both the vision and the capability to take your network communications to where you need them to be. Allied Telesis has been supplying network communications solutions for over 30 years. Today we are engaged in some of the most advanced and innovative next-generation network research, focusing efforts on development and production of more intelligent, autonomously controlled and managed systems that will be required to meet the demands of a world of Internet Things and smarter everything. The capabilities and performance of next-generation networks will be defined by the software that configures, secures, manages and automates the infrastructure. Our R&D investments are putting us on the main stage in the exploding era of IoT. As cloud computing uses servers, applications and other resources linked via a network, the infrastructure of that network and the ability to autonomously discover, manage, troubleshoot and resolve network issues will become fundamental to network operations. We also take advantage of our position as a network specialist to provide software solutions needed for network administration. These range from administration and monitoring of network equipment to authentication of connected devices and network status analysis. Our world-class global professional services organization offers unsurpassed support together with network design recommendations, project consultation, staging services and post-installation support.
