Best Data Loss Prevention Software for 2020

eWEEK is creating a new series of articles which examine all sectors of IT and present up-to-date research and analysis on the leading companies in each space. It's all designed for enterprise buyers of hardware, software, services and cloud products to have more and better information in hand when the time comes to make an investment.


Data is now at the center of everything digital—and protecting it is a growing headache for organizations large and small. One of the keys to addressing this challenge is data loss prevention (DLP). It relies on software algorithms to detect potential anomalies, ex-filtration transmissions and data breaches. DLP protects against misuse and abuse—as well as unauthorized access—by analyzing content and examining the contextual composition of files, messages and applications running on premises or in the cloud. DLP can spot problems for data at rest and in motion.

DLP encompasses an array of tasks. These include: rule-based expressions that examine credit card or Social Security numbers, database fingerprinting, exact file matching, partial document matching, lexicon analysis and statistical analysis. It may also include rules for pre-built categories, such as PCI or HIPAA. Of course, different vendors have adopted markedly different approaches to identifying potential issues, problems and breaches. As a result, it’s vital for any organization looking to purchase a DLP product to understand how it matches an actual corpus of sensitive data to determine its accuracy and value for the enterprise.

This is a fast-growing sector of IT: Gartner estimates that 90 percent of organizations use DLP in one form or another, up from about 50 percent in 2016. Although many solutions are designed for general data loss prevention, the space continues to evolve. Some products now focus on specific industry sectors, such as aerospace, defense and intelligence, banking, financial services and Insurance (BFSI), government, health care, manufacturing, retail and logistics and telecommunications. Many solutions also address specific requirements, including regulatory and compliance issues, for services such as AWS, Azure, Box and Office 365.

eWEEK has surveyed the marketplace in order to identify 10 of the top vendors in the DLP space. The accompanying profiles and information come from a number of prominent sources, including vendor websites, Radicati Market Quadrant, Gartner Peer Insights, G2 Crowd and Capterra.
