Top 15 Cloud Access Security Brokers of 2026

A CASB (cloud access security broker) is a control point between your users and cloud apps that gives security teams visibility and governance over how sensitive data moves through SaaS — enforcing data-protection, access, and compliance policies across both sanctioned and shadow cloud usage.

• What it does: discovers cloud and SaaS usage, enforces DLP, controls access, and flags risky sharing.
• The four pillars: visibility, compliance, data security, and threat protection.
• Where Strac fits: Strac delivers the data-security pillar — finding and remediating sensitive data inside your SaaS apps inline.

As organizations increasingly pivot their operations to the cloud, the requirement for robust security measures has never been more crucial. Cloud Access Security Brokers (CASBs) play a pivotal role in safeguarding sensitive data & ensuring compliance with regulatory standards across various cloud applications. 

These solutions serve as intermediaries between users and cloud service providers, providing visibility, control, and protection against potential threats. In 2026, the landscape of CASBs features numerous players, each offering unique capabilities and advantages. 

In this blog we explore the top 15 cloud access security brokers, highlighting their key features, strengths, and considerations to help businesses make informed decisions for their cloud security needs

Key Requirements to Look for in CASB Solution

✨ CASB Vendors, Tools & Software: What Actually Separates Them

Search for CASB vendors, CASB tools, or CASB software and you get the same fifteen logos. What separates them is the data-security pillar — can the CASB actually find and remediate sensitive data inside your cloud apps, or does it stop at visibility and access control? Strac delivers that pillar, with both a historical discovery scan and real-time DLP on every surface a CASB is meant to govern.

When evaluating a Cloud Access Security Broker (CASB) solution, several key requirements should be considered to ensure it meets your organization's security needs:

Comprehensive Visibility

A CASB should provide deep visibility into cloud usage, user activities, and data flows. This includes monitoring sanctioned and unsanctioned applications, as well as identifying potential shadow IT risks.

Data Loss Prevention (DLP)

Effective DLP capabilities are essential for protecting sensitive data. Look for features that allow you to enforce policies that prevent unauthorized data sharing or access, both within and outside the organization.

Risk Assessment and Compliance

The solution should offer continuous risk assessments and compliance audits. This helps organizations quickly identify vulnerabilities and ensure adherence to regulatory requirements.

Integration Capabilities

Ensure the CASB can seamlessly integrate with existing security tools and cloud services. This includes support for Single Sign-On (SSO) and identity management systems, which enhance user authentication and access control.

User Behavior Analytics

Advanced analytics capabilities are crucial for detecting unusual user actions that could indicate a security threat. Look for solutions that employ machine learning to analyze user activities and flag anomalies.

🌶️ Spicy FAQs for CASB Solutions

What is the best CASB solution in 2026?

It depends on your architecture. Netskope and Zscaler lead for inline, SSE-integrated CASB; Microsoft Defender for Cloud Apps wins inside E5 estates. If your priority is the data itself — finding and remediating sensitive data across SaaS rather than brokering access — an API-native platform like Strac covers what inline CASB misses, including data at rest and GenAI flows.

Is CASB being replaced by SASE?

Absorbed more than replaced: standalone CASB is folding into SASE/SSE platforms as one function among several. What that consolidation does not solve is content-level protection — data at rest in SaaS, sharing hygiene, and AI-agent traffic — which is why many stacks pair the SASE edge with a data-native layer. See our guide to the best DLP for SASE.

Do I need both CASB and DLP?

They answer different questions: CASB governs which cloud apps are used and how; DLP governs the sensitive data inside them. Modern platforms blur the line — Strac, for example, discovers shadow SaaS like a CASB while classifying and redacting the data like DLP — but evaluating them as one combined requirement is the safest way to avoid a coverage gap.

Choosing Strac as your CASB solution

Strac is a cutting-edge Cloud Access Security Broker (CASB) solution that focuses on data discovery, data loss prevention (DLP), and compliance management across various cloud and SaaS applications. With its no-code integrations and advanced machine learning capabilities, Strac enables organizations to automatically detect, block, and remediate sensitive data in real-time. This makes it an ideal choice for businesses looking to enhance their cloud security posture while maintaining compliance with stringent regulations.
