In this episode of CyberBytes, Shan Kulkarni, Co-Founder and CEO of Nullify, discusses why the biggest challenge in cybersecurity is no longer finding vulnerabilities, it's fixing them.

Shan shares how AI is changing the way security teams approach vulnerability remediation, why the industry is shifting its focus from detection to execution, and how organizations are using autonomous AI agents to close the growing patch gap.

We covered:

• Why AI is making vulnerability discovery easier than ever

• The remediation bottleneck facing security teams

• How Nullify uses AI agents to automate vulnerability patching

We covered:

• How AI is changing the identity security landscape

• Why the definition of “privileged” is expanding

• How AI agents can accumulate and exploit access at machine speed

• Why modern security needs to work with, rather than against, user workflows
