STORYBOARDS
Gartner on CASBs
Hybrid Architecture CASBs are a requirement [Forward Proxy, Reverse Proxy, API Integration]○ All three deployment modes may be required to deliver the security outcomes that the organization desires.
○ Many SaaS application providers do not yet have a rich set of APIs
○ When deployed in the data path (typically as a form of proxy) the CASB can provide detailed logging on all users and devices,
managed or bring your own device (BYOD), on what activities are occurring inside cloud applications and infrastructure.
Beware of API-only vendors○ Proxy mode CASBs are actually networking vendors; they are processing traffic similar to Web gateway vendors. This is a considerably
harder engineering exercise than that of using APIs... It will be considerably harder for API-only CASB providers to retrofit proxy
architecture to their platforms.
Managed/unmanaged device access control is required○ CASBs must be able to cover data… from any device type — managed or unmanaged — while accessing enterprise applications.
CASBs must include endpoint data protection components [Data protection on Devices]○ A CASB should handle not only the SaaS applications, but also how that data is tracked, delivered and stored on endpoints.
