Westermo designs and manufactures data communications products for mission-critical systems in physically demanding environments. The products are used both in social infrastructure, such as transport, water and energy supplies, as well as in process industries, such as mining and petrochemical.

The realisation that the needs of the industry are different from those of corporate IT creates growth in the requirement for industrial grade data communication. The industrial operating environments are tough and the impact of failure in the field can lead to business threatening situations demanding that products have a lifetime in excess of 10 years. These factors have resulted in a demanding and fast growing market place.
