FortiCASB review
An API-centric CASB for SaaS visibility, DLP, threat detection, and remediation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FortiCASB is Fortinet’s cloud-delivered Cloud Access Security Broker for organizations managing SaaS applications and cloud services. It is aimed at medium-sized and large cloud-service deployments that need API-based visibility, data protection, threat detection, configuration assessment, and remediation workflows. Connections use APIs, OAuth, or service accounts, allowing teams to monitor application activity, discover shadow SaaS, identify sensitive data and exposed files, and track user entitlements.
Its strongest fit is an environment built around widely used SaaS platforms. FortiCASB lists connections for Microsoft 365, SharePoint, Teams, Google Workspace, Gmail, Google Drive, Box, Dropbox, Egnyte, ShareFile, Slack, Zoom, Cisco Webex, Salesforce, and ServiceNow. Across those applications, its feature set covers cloud DLP policies, threat and malware detection policies, compliance policies and reporting, SaaS posture assessment, and corrective-action automation. The result is a monitoring and governance layer suited to teams that want one API-centric view across several cloud services, with AI features included.
FortiCASB is less suitable when inline inspection or inline enforcement is a core requirement. Its deployment model is API-based, with API controls and DLP controls, while inline CASB is provided by FortiGate, FortiProxy, or FortiSASE rather than FortiCASB itself. The published commercial model is contact sales, and licensing is based on protected users and data-scanning capacity. Choose FortiCASB for SaaS discovery, posture management, data security, and workflow-based remediation across connected applications; consider another approach when direct inline controls within the CASB service are essential.
