Understanding Data Loss Prevention (DLP)

Data Loss Prevention (DLP) is a set of tools and processes designed to detect and prevent the unauthorized use, transfer, or destruction of sensitive data. In an era where data breaches cost enterprises millions and AI tools like ChatGPT create new data exfiltration vectors, DLP has become mission-critical infrastructure for every organization.

Endpoint DLP

Protects data on user devices (Windows, macOS, Linux). Monitors file transfers, clipboard operations, printing, and USB usage. Nextguard endpoint agents provide real-time protection without impacting performance.

Network DLP

Monitors data in transit across the network. Inspects email, web traffic, and file transfers to prevent sensitive data from leaving the organization through any channel.

Cloud DLP (CASB)

Extends DLP policies to SaaS applications like Microsoft 365, Salesforce, and collaboration tools. Critical for organizations adopting cloud-first strategies.

Discovery DLP

Scans data at rest in databases, file shares, and cloud storage to find and classify sensitive information that may be unprotected.
