Frequently Asked Questions

Straight answers about how we build these rankings and how to use the data.

What is a CASB solution and what does it protect?

A CASB solution (Cloud Access Security Broker) is a security control point between cloud users and cloud service providers enforcing security policies for cloud application access, detecting shadow IT, preventing data loss, and identifying threats like account compromise and insider data theft. In 2026, the best CASB solutions deliver four core capabilities: visibility (what cloud apps are in use), compliance (are cloud apps meeting policy), data security (DLP for cloud data), and threat protection (detecting malicious cloud activity). CASB solutions are essential for any organization using Microsoft 365, Google Workspace, Salesforce, or AWS.

What are the best CASB solutions in 2026?

The top CASB solutions in 2026 are Palo Alto Prisma Access (best for multi-cloud deployments in unified SASE, 50,000+ app catalog), Forcepoint ONE CASB (best for granular cloud control and ITAR compliance), Lookout Cloud Security (best for mobile-centric cloud security and BYOD), Proofpoint CASB (best for advanced threat detection with email correlation), and Trend Micro Cloud App Security (best for email and Microsoft 365 collaboration tools). For SMBs, ManageEngine Log360 offers the best CASB solution with unified SIEM and DLP at the most affordable price point.

What are the top CASB solutions in unified SASE?

The leading top CASB solutions in unified SASE in 2026 are Palo Alto Prisma Access (CASB + SWG + ZTNA + SD-WAN in Prisma SASE), Forcepoint ONE (CASB + SWG + ZTNA), Lookout SSE (CASB + SWG + ZTNA + MTD), and Cisco Umbrella SSE (Cloudlock CASB + SWG + ZTNA). In a unified SASE architecture, CASB handles cloud application security while SWG handles web traffic inspection and ZTNA replaces VPN all delivered from a single cloud-hosted platform. Gartner recommends evaluating CASB as part of a complete SSE (Security Service Edge) or SASE evaluation rather than as a standalone product.

What is the best AWS CASB solution in 2026?

The best AWS CASB solutions for monitoring and securing AWS IaaS environments in 2026 are Palo Alto Prisma Access (deepest AWS API integration with 50,000+ app coverage), Forcepoint ONE CASB (AWS IaaS activity monitoring with ITAR compliance), McAfee MVISION Cloud/Trellix (AWS, Azure, GCP IaaS monitoring with four-pillar CASB), and Microsoft Defender for Cloud Apps (AWS connector for cloud app activity monitoring). For organizations running workloads exclusively on AWS, combining an AWS CASB solution with AWS native controls (CloudTrail, GuardDuty) provides the most comprehensive coverage.

What do the best CASB solutions Gartner recommends have in common?

The best CASB solutions Gartner consistently evaluates in its Magic Quadrant for Security Service Edge (SSE) share four capabilities: inline traffic inspection (real-time proxy-based blocking, not just API after-the-fact detection), API-based sanctioned app monitoring (for deep SaaS visibility), advanced DLP with data classification and content inspection, and UEBA with behavioral threat detection. Gartner also increasingly evaluates CASB as part of SSE platforms rather than standalone, emphasizing integration with SWG and ZTNA. In 2026, Gartner SSE Magic Quadrant Leaders Palo Alto Networks, Netskope, and Zscaler — all deliver CASB as a core SSE component.
