At the risk of stating the obvious to many CSO readers, a secure access service edge (SASE) solution is the best cybersecurity solution an enterprise can deploy today. SASE provides converged network and security capabilities that provide deep visibility, consistent security, and granular controls across the entire hybrid network.
To accomplish this, SASE is delivered as a service that combines the capabilities of SD-WAN and security service edge (SSE). SSE is a cloud-delivered security offering composed of secure web gateway (SWG), cloud access security broker (CASB), zero-trust network access (ZTNA), and Firewall-as-a-Service (FWaaS).
That’s a lot of functionality, and confusion persists about what each element does as an independent technology and as a part of SASE. In this piece, I’ll discuss the importance of CASB, specifically, and examine its role within SASE–particularly, why it’s critical to the solution’s success.
Why is CASB critical to SASE?
The rise of cloud computing and Software-as-a-Service (SaaS) has given organizations tremendous flexibility, scalability, and cost-savings while increasing collaboration. But, moving sensitive data to and from SaaS applications increases the risk of a breach and extends an organization’s attack surface. CASBs have emerged as a solution to this challenge because they provide deep visibility into cloud and SaaS deployments, allowing IT teams to protect users and sensitive corporate data in these environments.
The ultimate goal of a SASE solution is to provide a secure, efficient experience for employees no matter where they are working. As a part of SASE, CASBs handle cloud security risks and support work-from-anywhere employees who use personal, unmanaged devices to access SaaS applications from new, disparate locations.
