Jersey-based Calligo has bought Cork and Dublin-based Itomic Voice & Data for an undisclosed sum.

Calligo is the world's first end-to-end managed data services provider and has operations in Ireland, Canada, the US, the UK, the Channel Islands and Luxembourg, while its customers are worldwide.

It improves businesses' productivity and profitability by making their data more available, secure and safe.

The deal for Itomic Voice & Data marks Calligo's seventh acquisition in three years, and follows January's deal for Dublin-based DC Networks. 

The company said these two acquisitions combine to make Calligo one of the largest IT managed service providers in Ireland, and the only one to offer data privacy support at the heart of every service. 

"With the addition of Itomic Voice & Data, we are now one of the largest IT service providers in Ireland, with sizeable presence in both Cork and Dublin - Ireland's two largest economic regions - and the capability to serve businesses throughout the country," commented Julian Box, founder and CEO of Calligo. 

He said the company has focused its current expansion strategy on Ireland because of its growing number of innovative businesses developing new data-reliant tools and services. 

"We believe Irish businesses stand to gain enormously from our services and expertise, particularly in international data privacy," he added.
