Netskope: One of the original pure-play CASB vendors, Netskope is a leader in CASBs as well as SSE. Forrester Research says, “Netskope has shown innovation across its technology stack, including significant investments in an impressive new private global network, artificial intelligence and generative AI security.” Netskope has recently merged SWG functionality into its CASB tool.

Palo Alto Networks: Palo Alto touts its CASB as being “next-generation,” based on the proposition that it’s less a standalone product and more of a range of integrated solutions such as inline security, SSPM, and enterprise DLP. The Palo Alto CASB is designed to secure apps and data across cloud and hybrid workforce environments, protects data in transit between users and SaaS providers, facilities regulatory compliance and minimizes risks from shadow IT.

Proofpoint: Proofpoint CASB is focused on extending DLP and threat protection from email to cloud apps. Proofpoint takes a people-centric approach; it provides granular visibility into who creates sensitive data and who owns, downloads, uploads, shares and edits that data. It identifies users who have been successfully phished, and those who have been attacked most by hackers.
