Which Cloud Access Security Broker (CASB) deployment method uses broker connections between the cloud service and cloud consumer, without being inline with the cloud consumer and services?

The API-based deployment method for a Cloud Access Security Broker (CASB) operates by establishing broker connections between the cloud services and the cloud consumer. This method does not require an inline presence between the two parties, meaning that it doesn’t have to route data through the CASB itself. Instead, it leverages APIs provided by cloud service providers to monitor and secure access without being situated in the direct communication path.

Through API integrations, the CASB can enforce security policies, collect usage data, and conduct risk assessments effectively as it communicates directly with the cloud services. This approach is particularly advantageous because it allows for a more seamless integration with existing cloud services and can provide comprehensive visibility and control without the latency or complication that might arise from inline methods, such as a forward proxy or a reverse proxy.

In contrast, other methods, like forward and reverse proxies, require all traffic to be routed through the CASB, making them inline solutions that could potentially create bottlenecks. Therefore, the API-based deployment is optimized for flexibility and efficiency, enabling better performance while still maintaining strong security measures.
