MCAS as a Cloud Access Security Broker (CASB)

A crucial facet of MCAS’s function is its role as a Cloud Access Security Broker, or CASB. If you’re unfamiliar with the term, a CASB is designed to strike the balance between organizational flexibility and agility, and digital security. It acts as an intermediary for users accessing your cloud-based applications, assessing access credentials and “brokering” the access process.

So, how does MCAS embody the role of a CASB?

When a user attempts to access your cloud applications, they do so via the MCAS CASB. This intermediary works to assess the validity of the user’s access credentials and accordingly grants or denies access. This means if the credentials are invalid, access is not granted. If the credentials provide access only to a limited tier of data, access is restricted. If the credentials are valid and appropriate, access is granted without delay, ensuring high levels of app performance even for remote users.

But the role of MCAS as a CASB extends beyond access control. It’s also a monitoring tool that keeps track of user behaviour within your cloud applications. By continually scanning app usage, MCAS provides a vantage point from which to keep on top of resource access. This potent combination of automatic and manual monitoring capabilities helps to ensure full regulatory compliance.

Furthermore, MCAS can integrate with your existing business systems, including CRM, ERP, and other platforms, providing comprehensive visibility and capability. This seamless integration allows you to extend MCAS’s benefits without compromising on security or performance. This integrability is furthered by API-based interactions that can extend the usability of these solutions.

The benefits of employing a CASB like MCAS are multifold. With robust security mechanisms, user-friendly interfaces, seamless integrations, and real-time monitoring, MCAS streamlines your cloud application security and ensures that your business is well-protected and compliant.

Key Takeaway: As a Cloud Access Security Broker (CASB), MCAS balances organizational flexibility and robust digital security. It grants or denies user access based on the validity of credentials, monitors user behaviour, and ensures regulatory compliance, thus, providing a secure and user-friendly environment for your cloud applications.
