As for Microsoft, it must do more to secure its various communication and messaging channels, said David Raissipour, chief technology and product officer of Mimecast, an email and messaging security vendor.
"I have a lot of colleagues [at Microsoft] that are in the cyber space, and they're putting a lot of time and effort into it," said Raissipour, who worked at Microsoft in a variety of roles over 14 years. "Is it good enough? Not for the kind of scale they have and the breadth they have."
