Proofpoint CASB: Product Overview and Insight

See our complete list of Top CASB Vendors.

Proofpoint acquired FireLayers in 2017, adding CASB to Proofpoint’s threat response, mobile threat defense, remote browser isolation, and threat intelligence offerings. Proofpoint has a large installed base for its email security product; the target market for Proofpoint’s CASB is as an add-on for this installed base plus new customers not currently using Proofpoint products. Proofpoint CASB is aimed at small to large enterprises, from 300 users and up. It focuses on detecting and stopping threats, and access to risky services can be forced through a remote browser isolation mechanism that protects users, devices and applications from remote attack.

Notable features

  • Proofpoint CASB identifies top users at risk facing potential account compromise from threat activity across cloud and email.
  • The service combines contextual data, such as user device, location and login time, and user behavior analytics with global threat intelligence to detect cloud account compromise.  Machine learning helps detect unusual access attempts, non-human brute force campaigns and suspicious file activities after an account is compromised.

Works with: Proofpoint CASB works with Office 365, G Suite, Box, Dropbox, Salesforce, Slack, AWS and more.
