A California-based cyber security company is creating over 200 new jobs in Northern Ireland. 

Imperva, which has its headquarters in Silicon Valley, is to open a technology base in Belfast and plans to employ two hundred and twenty people. 

The new posts will have an average salary of £30,000 and will be aimed at new university graduates and experienced staff.

Imperva's new Belfast hub will support the company's customers in Europe.

The North's jobs creation agency, Invest NI, has given Imperva almost £1.5 million in grants towards the establishment of the new Belfast technology hub.
