Support for this show comes from Varonis. Do you wonder what your company’s ransomware blast radius is? Varonis does a free cyber resilience assessment that tells you how many important files a compromised user could steal, whether anything would beep if they did, and a whole lot more. They actually do all the work – show you where your data is too open, if anyone is using it, and what you can lock down before attackers get inside. They also can detect behavior that looks like ransomware and stop it automatically. To learn more visit www.varonis.com/darknet.
