Top Three Benefits of the Best CASBs
As the Cloud Access Security Broker (CASB) market grows more diverse and more competitive, you may be wondering whether a CASB would bring significant benefits to your organization’s cloud security. The short answer is that like any other technology, CASBs aren’t created equal. Capabilities vary, and so does effectiveness. Here are the top three benefits that the best CASBs can bring to your enterprise:
Cloud security consolidation
While useful for enterprises at any stage of their transition from on-premises infrastructure to third- party cloud service providers (CSPs), CASBs are especially impactful for organizations with multiple public cloud investments. Every CSP will provide a different set of access, authentication, and security tools, after all. Security administrators can quickly become overwhelmed trying to make sure that internal security policy monitoring and enforcement are consistent across a sprawl of different clouds, and when security administrators become overwhelmed, vulnerabilities can be overlooked, mistakes can be made, and breaches and exposure become much more likely to happen. The best CASBs will enable enterprises to consolidate all of their cloud security efforts into a single platform, enabling consistent visibility, reporting, and enforcement in a single interface that spans multiple cloud applications like Salesforce, ServiceNow, and AWS.
Improved compliance in the cloud
The multi-cloud consolidation that the best CASBs provide also enables enterprises to more effectively maintain their regulatory compliance and adhere to industry best practices, even in a multi-cloud environment. Typically, regulatory compliance demands several key capabilities:
The ability to apply encryption, tokenization, and other data protection technologies to specific data types on a granular, policy-driven basis.
In-depth and up-to-the-minute monitoring and visibility into user and data activities across all cloud deployments
Robust activity logging and reporting capabilities for audit and forensics purposes.
While each third-party CSP may provide some of these tools, wrangling all those capabilities in multiple clouds can become too much for an internal security team to handle. The security consolidation that CASBs deliver also creates compliance consolidation, which is critical to remaining compliant in acomplex environment.
Consistent access and identity management
Just as each third-party CSP will provide a slightly different set of security and compliance tools, so too will each third-party CSP have slightly different ways of handling user identities, access, and permissions, with some offering more granular options than others. This can lead to unfortunate lapses in data security, with information held more confidential in one cloud being more accessible in another, or with user access to one cloud being more strictly controlled than user access to others. The best CASBs will enable the enterprise to ensure consistency of access controls and identity management across all cloud deployments by providing an additional layer of security upon login to prevent unauthorized parties from gaining access to corporate cloud resources.
As you may have noticed, consistency is the common theme running through the top three benefits of CASBs. Inconsistency is a major cause of security weaknesses and data breach disasters; consistency helps to guarantee that your organization’s security and compliance strategies are carried out everywhere your organization’s sensitive data is transmitted.
