Top Use Cases for CASB
1. Discover and Control Shadow IT
When your users store and share corporate files and data in unsanctioned cloud apps, your data security suffers. To counteract this, you need to understand and secure cloud usage in your organization.
Zscaler CASB automatically discovers shadow IT, revealing the risky apps visited by users. Automated, easily configurable policies then enforce various actions (e.g., allow or block, prevent upload, restrict usage) on individual apps and app categories.
2. Secure Non-Corporate SaaS Tenants
Users may use both sanctioned and unsanctioned instances of apps like Google Drive. Responding by either allowing or blocking the app entirely can encourage inappropriate sharing or hamper productivity, respectively.
Zscaler CASB can distinguish between sanctioned SaaS tenants and unsanctioned instances, applying appropriate policy enforcement to each. Preconfigured SaaS tenancy controls deliver automated, real-time remediation.
3. Control Risky File Sharing
Cloud apps enable unprecedented sharing and collaboration. As a result, your security teams need to know who’s sharing what in sanctioned apps, lest you risk letting dangerous parties get hold of your data.
Collaboration management is a key capability of any effective CASB. Zscaler CASB quickly and repeatedly crawls files in your SaaS tenants to identify sensitive data, check the users with whom files are shared, and automatically respond to risky shares as needed.
4. Remediate SaaS Misconfigurations
When deploying and managing a cloud application, precise configuration is key to ensure the app functions properly and securely. Misconfigurations harm your security hygiene and can easily expose sensitive data.
Zscaler SSPM integrates with your SaaS tenants via API to scan for misconfigurations that could jeopardize regulatory compliance. It’s one component of Zscaler Workload Posture alongside CSPM and CIEM.
5. Prevent Data Leakage
In addition to cloud resource misconfigurations that could enable data breaches and leaks, you need to identify and control sensitive data patterns in the cloud. A vast amount of such data is regulated under frameworks like HIPAA, PCI DSS, GDPR, and many others.
The Zero Trust Exchange, our cloud native security platform, provides unified data protection with cloud DLP and CASB capabilities. It ensures cloud apps are properly configured to stop data loss and noncompliance, backed up with advanced data classification techniques to identify and secure sensitive data wherever it goes.
6. Prevent Successful Attacks
Once an infected file gets past your organization’s security into one of your sanctioned cloud apps, it can quickly spread to connected apps and other users’ devices. That’s why you need a way to defend against threats in real time both at upload and at rest.
Zscaler CASB thwarts malware’s advances with advanced threat protection (ATP) capabilities, including:
- Real-time proxy to prevent malicious files from being uploaded to the cloud
- Out-of-band scanning to identify files at rest and remediate threats
- Cloud sandboxing to identify even zero-day malware
- Agentless Cloud Browser Isolation to secure access from unmanaged endpoints
