In episode 735, join Rob Walling for a solo adventure where he categorizes the different levels of SaaS platform risk. He introduces a framework with three key factors: Replacement, Customer Concentration, and Lead Flow. Rob then defines eight levels of risk according to these factors and other vulnerabilities such as relying on open source – a hot topic with recent news about WordPress, WP Engine, and Automattic.
