TL;DR: Traditional Data Loss Prevention (DLP) struggles with data exfiltration via modern cloud applications and browser tools due to encrypted traffic, Shadow IT, and personal storage. A robust solution requires a layered defense strategy combining Cloud Access Security Brokers (CASB), Next-Generation Endpoint DLP, and Secure Web Gateways (SWG) for comprehensive visibility and real-time enforcement.

Struggling to stop data leaks via cloud apps and browser tools? Discover robust Data Loss Prevention (DLP) strategies leveraging CASBs, advanced Endpoint DLP, and Secure Web Gateways to truly catch and prevent sensitive data exfiltration in modern IT environments.

The modern enterprise relies heavily on cloud services and browser-based applications. While this enhances productivity and collaboration, it also introduces significant challenges for data security, particularly in preventing sensitive data loss. Traditional network-based DLP solutions, often designed for on-premises file shares and email, frequently fall short when faced with encrypted SaaS traffic, personal cloud storage, browser extensions, and sophisticated web applications. This post delves into the symptoms of this pervasive problem and offers three distinct, yet complementary, solution approaches.

If your organization is struggling with data exfiltration through cloud services and browser tools, you’re likely experiencing some of these common symptoms:

Addressing these symptoms requires a multi-faceted approach, moving beyond legacy DLP to solutions designed for the cloud-centric world.

A CASB acts as a gatekeeper for cloud services, providing visibility, compliance, data security, and threat protection. Its DLP capabilities are specifically tailored to cloud application usage.

Consider a scenario where you need to prevent employees from uploading documents containing Personally Identifiable Information (PII) to personal cloud storage accounts (e.g., personal Dropbox) while still allowing uploads to sanctioned corporate cloud storage.

A CASB would achieve this through a policy engine, often configured via a web UI, but conceptually, it translates to rules like this:

This policy, enforced either via API integration (for sanctioned apps) or inline proxy (for unsanctioned/real-time), effectively stops data exfiltration to personal cloud services.
