Top 10 CASB Solutions

CASB solutions were built to extend security from on-prem networks into the cloud. When companies moved to SaaS and multi-cloud, they needed visibility and control over who was accessing what.

But the problem today isn’t just “cloud.” It’s sensitive data moving constantly across Slack, Google Workspace, Salesforce, Snowflake, and AI tools like ChatGPT.

Modern CASB solutions need to do more than monitor traffic. They must:

• Discover and classify sensitive data across SaaS apps
• Enforce granular policies across users and APIs
• Detect risky sharing
• Remediate exposure in real time

Platforms like Strac go beyond traditional CASB by combining visibility, data discovery, classification, and inline redaction in one system. Instead of just alerting you, they help you fix the risk immediately.

In this guide, we break down the 10 best CASB solutions in 2026 and what actually matters when protecting SaaS and AI-driven environments.

What Is a CASB Solution?

A CASB solution; Cloud Access Security Broker; sits between your users and your cloud applications. Its job is simple: give security teams visibility and control over how data moves across SaaS and cloud environments.

In practice, CASB solutions monitor user activity, enforce security policies, detect sensitive data exposure, and help prevent data loss across tools like Google Workspace, Salesforce, Slack, and other cloud platforms.

Modern CASB solutions go further. They don’t just inspect traffic; they help discover sensitive data, classify it, and enforce policies consistently across multi-cloud, SaaS, and even AI tools.

How Are CASB Solutions Helpful for Organizations?

CASB solutions are helpful because cloud apps create blind spots. Employees share files, connect third-party apps, use AI tools, and move data outside traditional network controls. Without a CASB solution, security teams lose visibility.

A strong CASB solution helps organizations:

• See which SaaS apps are in use; including shadow IT
• Monitor user behavior and risky activity
• Detect sensitive data like PII, PHI, or PCI in cloud apps
• Enforce sharing policies and prevent unauthorized access
• Support compliance requirements such as GDPR, HIPAA, and SOC 2

In short, CASB solutions help organizations control cloud risk without slowing down productivity; which is critical in today’s SaaS-first, AI-enabled environments.

✨ CASB Use-Cases

1. Visibility into Cloud Usage

• CASBs provide granular visibility into which cloud applications are being used, how they’re being used, and by whom. This helps organizations track shadow IT and ensure that only approved apps are accessed.

2. Data Loss Prevention (DLP)

• A CASB ensures that sensitive data (e.g., PII, financial data, etc.) is not shared or leaked to unauthorized users or external parties through cloud applications. They can scan content for sensitive information and apply encryption, redaction, or blocking.

3. Threat Protection

• CASBs can detect and respond to abnormal behaviors, such as a compromised account accessing large amounts of sensitive data or performing unauthorized activities. This involves identifying malware, ransomware, or insider threats within cloud applications.

4. Compliance Monitoring

• CASBs help organizations comply with regulatory standards like GDPR, HIPAA, PCI-DSS, etc., by ensuring that data is handled, shared, and stored in compliance with these regulations across cloud services.

5. Access Control and Identity Management

• CASBs enable organizations to enforce strict access policies based on user role, device, location, or other factors. For instance, users can be allowed to view certain data from secure locations but blocked from downloading it from public networks.

6. BYOD (Bring Your Own Device) Protection

• With the increasing use of personal devices for work, CASBs can ensure that data accessed via non-corporate devices is secured, controlling actions like downloads, uploads, or sharing sensitive data.

7. Monitoring and Managing API Use

• CASBs monitor how APIs are used by applications and users to access cloud services. They ensure secure API connections and prevent unauthorized or risky API usage.

8. SaaS and Cloud Security

• CASBs protect against unintended sharing of sensitive data via collaboration platforms like Google Drive, Slack, or Microsoft Teams, ensuring that data isn’t accidentally shared with external users.

9. Control Over SaaS, PaaS, and IaaS

• CASBs offer security for all types of cloud services—whether it's software, platform, or infrastructure as a service—by providing governance over the data and applications used in these environments.

10. GenAI and Data Protection

• With the rise of generative AI models, CASBs help control what data is fed into these models, ensuring sensitive customer or business data is not used to train AI without proper safeguards.
