Navigating the Cybersecurity Twitterverse | 23 Influential Accounts to Follow in 2023

by SentinelOne

Since our last post showcasing prominent cybersecurity accounts worth your follow, Twitter has occupied much of the limelight with stories about the tumultuous “takeover” including lawsuits, layoffs, and circulating concerns about free speech. Following Elon Musk’s acquisition in October 2022, many Twitter users flew the coop and migrated to the more decentralized social media platform Mastodon.

Though the open-source and crowdfunded Mastodon saw a huge surge in new accounts last winter, many new Mastodon users struggled to rebuild their complex social networks and have since returned to the blue bird app. For the cybersecurity community, Twitter remains the primary social media channel for all things cyber.

In the spirit of expanding our knowledge and resources, here are 23 hand-selected Twitter accounts we recommend to all those interested in learning about a wide variety of cybersecurity topics, issues, and news!
