A complete review of the Best Data Loss Prevention Software for Linux. Compare and select the right Linux DLP Service for your organization:

In this article, we have defined the DLP and its importance with its market share and some expert advice. We have reviewed individually and compared the top DLP tools on different factors. Some FAQs are also mentioned for better understanding.

Data Loss Prevention refers to the process of preventing the loss, misuse, or leakage of sensitive data of the organization from different sources like mobile devices, websites, USB, cloud, ISP, email, etc.

By data loss, we mean any unwanted event in which the data may get deleted or attacked like in a ransomware attack, where the attacker locks the data and demands payment for unlocking it. Insider threats may cause data leaks, extrusion by attackers, or unintentional or negligent data exposure.

Data Loss Prevention software helps the organization in securing data in motion, data at use, data at rest, or endpoint. It identifies sensitive data automatically by machine learning and detects any leakage or transfer that is suspicious.

Linux DLP – Best DLP Solutions For Linux

Best Data Loss Prevention Software For Linux

There are three main use cases of DLP software: Personal Information Protection and compliance (where it identifies and classifies sensitive data and monitors activities related to that data with regulatory compliance), Intellectual Property protection, and Data Visibility (tracking data on endpoints, networks, and cloud).

This tutorial on Data Loss Prevention Software for Linux will give you a clear idea of which DLP service you must choose.

Importance of DLP software:

  • Secure data, Protect Intellectual Property with regulatory compliance: It helps in identifying and securing sensitive data of the organization from unauthorised transfers, losses, or leaks by adhering to regulatory compliance.
  • Protection against threats caused by BYOD: It prevents sensitive data from being exposed to the devices when they are connected to the organization BYOD (Bring Your Own Device) is prevailing.
  • Monitoring employee activities: It monitors the employees’ activation of the device can limit the use of web surfing and can control which applications employees can access to eliminate time wastage.
  • Prevent misuse of data at endpoints: It monitors activities on all endpoints and can prevent printing, copying, and pasting if needed. It gives full data visibility and control to ensure the prevention of data leakage.
  • Competitive advantage: By protecting sensitive data from being leaked or misused, the organization can gain a competitive advantage in both brand value and reputation. Otherwise, it will end up in the financial, reputational, and legal line of fire.

Market Trends: According to the research by Maximise Market Research, the market for Data Loss Prevention (DLP) is expected to grow with a CAGR of 3.2% from $2.5 billion in 2021 to $3.75 billion in 2027. The key reason for the increase in this market is reported to be the use of the cloud for data storage, and the majority of the growth has come from America and the Asia Pacific.
