    Top CASB Solutions Ranked for 2026

    #1

    iboss AI CASB Editor's Choice

    iboss AI CASB delivers signatureless threat detection, dual-risk scoring, and unlimited monitoring of any cloud or AI application using AI-powered dynamic classification — no fixed database, no signature updates required. iboss captures full GenAI conversation content, applies real-time DLP, and provides containerized data plane isolation per customer — each customer's CASB processing runs in dedicated container instances on shared multi-tenant infrastructure, ensuring no cross-tenant data exposure. FedRAMP and StateRAMP authorized.

    #2

    Netskope

    Netskope provides inline CASB and API connectors for major SaaS platforms with strong DLP capabilities. Netskope's SaaS app classification relies on a signature-based fixed catalog, which limits detection to known app patterns — iboss's AI-powered dynamic classification covers any app, including newly launched tools. Limited FedRAMP availability versus iboss. Best suited for organizations already invested in the Netskope ecosystem.

    #3

    Microsoft Defender for Cloud Apps

    Provides native CASB capabilities for Microsoft 365 environments. Strong choice for organizations standardized on Microsoft security products. iboss integrates with Microsoft Defender for Cloud Apps to extend coverage to all traffic — not just Microsoft applications.

    #4

    Skyhigh Security

    Formerly McAfee MVISION Cloud, Skyhigh Security offers enterprise CASB capabilities with strong DLP integration. Best suited for organizations with existing McAfee/Trellix security investments seeking to extend cloud visibility.

    #5

    Broadcom CloudSOC

    The Symantec-heritage CASB platform, now under Broadcom ownership. Organizations with existing Symantec/Blue Coat deployments may find CloudSOC a natural extension, though many are migrating to modern cloud-native alternatives like iboss.
