Lewis PR has won a five-figure retained brief to boost the profile of an anti-paedophile software firm.
Swedish firm NetClean provides technology to block, tag and flag when child pornography is distributed on corporate networks.
Lewis, which won the account from Rocket PR, will run a campaign that involves raising awareness of the growing problem of child abuse images being distributed on memory sticks and stored on work computers.
Elizabeth Littlewood, director of Lewis' UK technology practice, said: 'It's extraordinary how many businesses are unaware that their corporate networks are being used for such terrible purposes. NetClean is at the forefront of the battle to better protect children and is constantly innovating in order to combat the spread of child abuse images.'
NetClean founder Pelle Gara said: 'Most people are under the illusion that paedophiles are unemployed or don't work in office environments. In fact, the opposite is true. A large percentage of offenders are from a stable background with an unblemished record, making them difficult to spot.'
NetClean's products include NetClean ProActive, an application that totally blocks access to child sexual abuse content. By comparing existing imagery, NetClean ProActive can stop a single photo or video, both from internet and USB devices, in contrast to web filters that only block prohibited addresses. NetClean's image recognition technology alerts IT and HR staff to potential obscene images via pre-existing hash codes, such as those used on widely circulated images.
NetClean works closely with several non-profit organisations, for example the World Childhood Foundation, ECPAT, Friends and Internet Watch Foundation.
