SaaS applications are cloud apps owned and managed by an application service provider, but you retain full control of the data, including who can create, access, share, and transfer information stored in the hosted application. Although most SaaS applications allow you to configure rules about sharing and exposing data, rules vary from application to application, which makes it challenging to ensure consistent security policy across all applications, assets, and users.

Data Security provides centralized policy and enforcement for your applications so you can protect your corporate data at all times. The service scans content to detect data exfiltration and malware propagation, monitors user activity, and provides activity-based alerting to notify you of malicious or risky behavior. This visibility allows you to assess incidents, quarantine users and data, and remediate any violations to protect against threats caused by malware, inadvertent sharing, excessive permissions, and data exposure.
