All links and images for this episode can be found on CISO Series CISOs agree that multi-factor authentication is the one security control that once deployed has the greatest impact to reduce security issues. Yet with all that agreement, it’s still so darn hard to get users to actually use it. This week’s episode is hosted by me, David Spark (@dspark), producer of CISO Series and Mike Johnson. Our guest is Arvind Raman (@arvind78), CISO, Mitel. Huge thanks to our sponsor, Horizon3.ai See your enterprise through the eyes of the attacker, identify your ineffective security controls, and ensure your limited resources are spent fixing problems that can actually be exploited. More from Horizon3.ai. In this episode: If MFA is so great, why is it not more widespread? Are high valuations for cloud security startups a vote against cloud providers doing cloud security well? What is the biggest challenge in deploying zero trust on existing infrastructure? Are there universal security red flags?
