119 InfoSec Experts You Should Follow On Twitter Right Now

Written by

Staying on top of trends and news should be easy in the information age but still proves difficult. Seeking out the best resources for information and the most trusted voices can seem overwhelming when social media outlets like Twitter make it easy for anyone to comment on topics or share links. Below are 119 Twitter accounts that you should be following in order to be ahead of the IT curve.

Many currently existing lists either include very few women or create separate lists of women. According to the Women’s Society of Cyberjutsu, women make up 50% of the general workforce and 25% of the computing workforce but only 11% of the information security workforce. Our list includes 29 women as well as 1 women’s organization.

There are definitely many other influential InfoSec experts that are worthy of following on Twitter. But we wanted to make sure to highlight this group because we felt they had a lot of relevant expertise in InfoSec and they shared great content. If you have someone that you’d like to show some love to and recommend, please let us know in the comments and we will consider that person for one of our next lists.
