What is the Critical SaaS SIG?


The Critical SaaS (CSaaS) SIG serves as a forum for CSaaS companies to collaborate on a collective defense strategy to improve the security and operational resiliency of their services and share intelligence information with the industry at large. It aims to increase the level of trust that customers can place in their organizations and the SaaS sector.  The CSaaS SIG enables companies who are essential to the internet to share cyber threat intelligence and effective security practices.  It also provides a framework for these companies to collaborate on future security issues.
