About Us


Asystec was established in 2011 by Les Byrne & Brendan McPhillips. From small beginnings; with just three employees based in Limerick, today the company has offices across Ireland and North America, and an international customers base far beyond.

Having both worked within the industry for a number of years, Les and Brendan gained vital experience and accumulated many accreditations along the way. These industry experiences lead to the recognition of an opportunity for a partner that would provide a high level of service.

Asystec are customer driven, differentiating ourselves from competitors through our unrivalled vendor knowledge and management skills. We offer expert, unbiased advice together with cost efficient solutions. Our goal is to guide our customers through every stage of their data management queries, right through the implementation process with an exceptional after care service. With our highly specialised team always at hand we are the ideal partners to help you deliver IT services to your organisation.
