GBHackers’ 2025 feature, written by Varshini on 25 October 2025, surveys the Top 10 Best Cloud Access Security Brokers (CASB) as organisations increasingly rely on multi-cloud environments. It highlights Netskope, Palo Alto Networks Prisma Access, Microsoft Defender, Forcepoint, Zscaler, Broadcom Symantec, Proofpoint, Skyhigh, Cisco Cloudlock and Trend Micro as leading options, chosen for their comprehensive CASB capabilities, multi-cloud support and integration potential.

The piece explains four pillars underpinning a modern CASB—Visibility, Data Security (DLP), Threat Protection (UEBA), and Compliance and Governance—alongside deployment modes such as API, reverse proxy and forward proxy. It notes that readers should evaluate platforms for features like shadow IT discovery, advanced DLP, adaptive access controls and integration with SIEM/SOAR or broader security ecosystems.

The article also discusses the trend towards integrated SASE and AI-enabled threat detection, emphasising that selecting a CASB is essential for protecting data, ensuring regulatory compliance and maintaining control as cloud usage grows.
