Katie Moussouris

Moussouris chose to use her hacking chops for good and eventually became a pioneer of cybersecurity. She now helps businesses and government agencies defend themselves against digital threats. Her portfolio includes work for the U.S. Department of Defense and Microsoft. But the real reason she made it on our list of the top women in tech? One of her life goals is "to help make the internet safer for everyone." For that, we thank you, Katie.
