If you’re evaluating Trend Micro Cloud App Security for cloud access security broker (casb) software, the three strongest independent alternatives in our editorial ranking are Netskope, Microsoft Defender for Cloud Apps, Forcepoint CASB. Each has a different best-fit buyer — the right choice depends on team size and workflow, not on which has the loudest review-site presence.
Why Trend Micro Cloud App Security sometimes isn’t the right pick: Pure CASB buyers without Trend XDR investment (Netskope or Microsoft better), buyers needing deep DLP or inline CASB enforcement. See full “worst for” verdict →

Which alternative for which buyer
Netskope
Deepest CASB heritage with full SSE breadth and persistent IPO speculation.
Mid-market to enterprise buyers (1,000-50,000+ employees) leading with CASB or DLP needs and consolidating multiple cloud-security tools onto one SSE platform.
SMBs under 500 employees (overkill, Microsoft Defender for Cloud Apps via E5 or iboss cheaper), Microsoft-anchored shops with M365 E5 already paid for, or buyers wanting transparent published pricing.
Microsoft Defender for Cloud Apps
CASB bundled into Microsoft 365 E5; default for Microsoft-anchored buyers.
Microsoft 365 E5-licensed organizations (any size) where the CASB is effectively bundled, or Microsoft-anchored shops standardizing on Defender XDR.
Google Workspace-anchored shops, AWS-native cloud-first organizations, Slack-first companies, or buyers needing deepest CASB feature depth (Netskope better).
Forcepoint CASB
Legacy Forcepoint CASB now consolidating into Forcepoint ONE under Francisco Partners.
Existing Forcepoint multi-product customers (NGFW + DLP + CASB + web) maintaining current investment, or federal / regulated buyers leveraging Forcepoint ONE FedRAMP authorization.
Net-new buyers without existing Forcepoint stack (Netskope or Microsoft cleaner choices), Microsoft 365 E5-anchored shops, or buyers wanting transparent published pricing.
Trellix CASB
McAfee Enterprise + FireEye merger product line under STG with persistent roadmap-clarity questions.
Existing Trellix XDR multi-product customers maintaining their stack, or buyers wanting CASB tightly coupled with XDR cross-signal.
Net-new CASB buyers without existing Trellix investment (Netskope or Microsoft cleaner), buyers seeking clear product-line roadmap, or organizations sensitive to PE-ownership turbulence.
Cisco Cloudlock
API-based CASB folded into Cisco Secure Access; standalone procurement is rare.
Cisco-anchored customers consolidating onto Cisco Secure Access; existing Cloudlock customers maintaining investment.
Non-Cisco buyers (Netskope or Microsoft cleaner choices), buyers needing inline CASB depth, or organizations wanting transparent published pricing.
Lookout
Mobile + endpoint heritage with CASB inherited from CipherCloud merger.
Organizations (500-25,000 employees) needing mobile-threat defense plus CASB in one vendor, especially BYOD-heavy or regulated industries with mobile workforce.
