So proud of the Cybereason team for being placed as a LEADER in the latest Endpoint Protection Magic Quadrant and having the largest positive jump year-over-year, moving from “Visionary” in our debut 2021 MQ placement, to well into the “Leader” Quadrant. https://t.co/fzbt5cNFH4

As we prepare for RSAC 2023, I'm looking back on 2022 with gratitude that we could meet as an industry face-to-face again. I had the honor of representing Cybereason at last year's RSA, Black Hat, and in front of a packed room at GrrCon. Let's raise the bar even higher in 2023!

I am exceptionally proud of Cybereason's performance in the MITRE ATT&CK Evaluations. The unadulterated evaluation results speak for themselves. https://t.co/WQdBBB8hFp

New research from Cybereason on Iranian threat actors finds link between ransomware and cyber espionage and highlights how attacks blend nation-state adversary and cybercriminal tactics and motives. https://t.co/z0udNj2Fkk

"The ability to collect data is one thing, but converting data into knowledge and actually understanding what to do with it is what a lot of companies are struggling with," says @Cybereason's @LiorDiv. #Disruptor50 https://t.co/QUgidsXxpD

In this edition of "The Cybereason Difference," we’re exploring our most beloved differentiator: the Malop™. Our unique approach to alerting that battles alert fatigue and ensures attackers aren't hiding in the noise. https://t.co/joJJIS7vUW #cybereason

[Justin T. Buchanan @JTBuchanan]

We interview a lot of customers—how else will we know we’re getting it right?—and one thing keeps coming up that makes me smile ear to ear every time: Penetration testers HATE Cybereason. https://t.co/0dI8bbarxV #cybereason

[Cybereason @cybereason]

The #infosecurity evolution continues. Stop chasing alerts, start ending malicious operations.

"Cybereason XDR takes an operation-centric approach to security—combining endpoint telemetry with behavioral analytics across the environment." From @Forbes
