Former Twitter chief information security officer Lea Kissner is joining cloud-security company Lacework, The Wall Street Journal reports. Kissner was among the members of Twitters' privacy and security teams to resign after Elon Musk purchased the company last fall. Lacework is restructuring after laying off 20% of its workforce in May 2022. "My first step is go in and see the lay of land and see what we need and where we can improve and where we're doing really well," Kissner said.
