On Thursday, technology investment firm Thoma Bravo LLC announced it has completed its $2.1 billion acquisition of information security company Imperva Inc., first announced in October. Now Imperva is letting go dozens of the 500 people it employs in Israel, according to three people familiar with the matter who spoke to Calcalist on condition of anonymity.

Employees at the company have started to receive termination letters Monday, the people familiar with the matter said.

Imperva confirmed the layoffs to Calcalist, but stated the company intends to maintain its operations in Tel Aviv and central Israeli town Rehovot.
