The correct answer isDbecause the core value of aCloud Access Security Broker (CASB)is to providevisibility, compliance, data protection, and threat prevention for SaaS applications.Aruba CASB helps prevent sensitive or restricted data from being uploaded, shared, or leaked through SaaS platforms (e.g., Microsoft 365, Salesforce, Google Workspace). This directly addresses compliance and data loss prevention (DLP) challenges.
Relevant extracts from official HPE Aruba Networking documentation:
“CASB solutions secure the use of SaaS applications by enforcing policies that prevent unauthorized sharing of sensitive or restricted data.”
“Aruba CASB provides inline controls and API-based integrations to detect and block risky SaaS activity.”
“By preventing data exfiltration and ensuring compliance, CASB closes a major cloud security gap introduced by uncontrolled SaaS adoption.”
“CASB helps IT maintain visibility into SaaS usage, ensuring data security and compliance across distributed environments.”
Why the other options are incorrect:
AQuality of experience improvements for branch SaaS apps are enabled bySD-WAN optimization, not CASB.
BReal-time app acceleration is aWAN optimization and SD-WAN function, not CASB.
CReplacing VPNs with secure alternatives is handled byZTNA (Zero Trust Network Access), not CASB.
