CASBs can, in fact, take action on the issues they highlight.
The comment by the gentleman from Evident.Io is plainly inaccurate. Multi-mode CASBs have gone far beyond Discovery for many years and can take a multitude of actions on anomalies, threats detected, DLP violations etc... both inline and out-of-band, including access control, alerting, quarantine, blocking, coaching, redirecting, encrypting/tokenizing and more. These actions can be taken across all modes, from out-of-band APIs to reverse proxy or full forward proxy.  They can be integrated with existing DLP, UBA, Threat Detection and IR solutions for end-to-end closed-loop remediation.

Re: CASBs can, in fact, take action on the issues they highlight.
Thanks for your response to the article. I work with Tim at Evident.io, and while I understand your points, I want to clarify some things. Taking action is not sending the data off to a non-CASB product and throwing the issue over the wall.  Sure, if you are a legacy man-in-the-middle approach to control you can attempt to take action, but architecturally this would fail when cloud services are accessed outside the networks behind the CASB solution. "Public Cloud" is exactly that... unconstrained access from anywhere in the world. This is where the CASB approach fails. No CASB player has full API coverage for public cloud and therefore cannot lay claim that they are true hybrid coverage solutions, much less process the environments in real time and mitigate risk across the overall attack surface. Integrations with other point products is a referral network, and not core CASB remediation capability.
