Cloud Access Security Broker

An examination of the Cloud Access Security Broker marketplace

The state of the CASB marketplace including current and future trends, and an examination of the leading vendors, including thorough and honest assessments from UK and European-based customers.


In the pre-cloud, exclusively on-premise days, organisations had a perimeter which they could protect and control. Everything inside was theirs, everything outside was not. Enforce your security policies inside the perimeter, make sure nothing nasty hops over the wall: job done.

Today, corporate data and systems are hosted anywhere and everywhere. Often technology leaders don’t even know where their data sits, or who else shares the servers on which their critical systems run.

How can security principles be applied to such a disparate system?

One answer, is a Cloud Access Security Broker (CASB). This is a system which enforces an organisation’s security policies across the cloud, sitting between the cloud provider and the corporation consuming its services. It’s a concept which has been gaining traction in recent years, with the market set to be worth in the region of $7.5 billion by 2020 according to many estimates.

There are a wealth of CASB suppliers available today, with traditional security vendors like McAfee (following its January 2018 purchase of SkyHigh Networks) and Symantec, software behemoths like Microsoft and Oracle, and smaller, specialist outfits like Netskope and Okta all in the game.
