Cloud access security brokers absorb shadow SaaS (2015–2018)
Employees adopted Salesforce, Dropbox, and Google Apps without IT approval. A new tool class, cloud access security brokers (CASBs), emerged to discover and control that shadow SaaS usage.
CASB vendors like Netskope grew fast selling visibility into unapproved cloud apps.
The brokers were absorbed into larger secure-access (SASE and SSE) platforms as the market consolidated.
Shadow AI is the new shadow IT. The pattern repeats: a visibility tool appears, then gets folded into the broader platform—exactly what Fortinet is doing with FortiEndpoint.
