CISO Series Podcast

David Spark, Andy Ellis, Steve Zalewski

Booking Overview

This is a recurring cybersecurity interview and debate show featuring security practitioners, CISOs, cybersecurity operations leaders, vendors, and industry analysts discussing practical security strategy and collaboration. Agencies could credibly pitch experienced CISOs, security executives, cyber operations leaders, and respected security analysts with enterprise or regulated-industry expertise; booking difficulty is medium because guests generally hold senior roles but are not necessarily mainstream public figures.
