Broadband provider Eclipse Internet is offering to protect 100 businesses with its EmailShield service for free this Christmas.
Launched in November, the service is able to catch up to 99 per cent of spam, stop viruses before they reach a business network and reduce data storage costs, the firm said.
Clodagh Murphy, Director of the internet service provider (ISP), stated: "We know how important it is for businesses to keep their networks safe - with many offices being left empty over the Christmas period, networks need to be properly protected from viruses and spam to make the return after the Christmas break as smooth as possible."
She explained that EmailShield is a hosted solution, which means updates are handled by the ISP and there is no need for businesses to worry about new virus threats.
All emails are filtered before they hit businesses' own exchange servers, reducing storage requirements for unwanted mail, Ms Murphy explained.
"We wanted to show our support for businesses - during the Christmas period we are offering 100 businesses the opportunity to have EmailShield protection at no cost to them," she stated.
"All we will ask in return is a little bit of feedback on how it performs."
Earlier this year, Eclipse Internet was awarded the Best Customer Focus prize at the Best Business Awards 2010.
