In 2024, Cloud Access Security Brokers (CASBs) remain vital for securing cloud applications and preventing data loss. Below, we review the top 10 CASB solutions, drawing insights from G2 and Gartner reviews.
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.
CASB Vendors: Strac Endpoint DLP
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.
CASB Vendors: Alert or Block external file sharing on Google Drive, Sharepoint, Box and other cloud drives
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.
20. 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.
