Gartner Market Guide for Data Loss Prevention

Tessian Named as Representative Vendor in the 2021 Gartner Market Guide for Data Loss Prevention


The latest Gartner Market Guide for Data Loss Prevention states, “The enterprise DLP market is mature, but integrated DLP and cloud-provider-native DLP solutions offer emerging capabilities that are much needed by security and risk management leaders starting DLP programs. This research offers guidance on market trends and their impact on data security strategies.”

According to Gartner, “The market for DLP technology includes offerings that provide visibility into data usage and movement across an organization, as well as dynamic enforcement of security policies based on content and context at the time of actions on data. DLP technology seeks to address data-related threats, including the risks of inadvertent or accidental data loss and the exposure of sensitive data, using monitoring, alerting, warning, blocking and other remediation features.”

Gartner Cool Vendor Report

Gartner, ‘Cool Vendors in Cloud Office Security’, Brian Reed, Ravisha Chugh, May 01, 2020


“Security and risk management leaders must revisit their organizations’ email security architecture in the light of current email threats, such as sophisticated malware, links to exploit kits, credential phishing, and BEC. Security professionals have known for years that, due to its importance as an attack vector, email security requires a layered approach. However, only a few vendors innovate their products at a pace that is similar to the attackers.” – Gartner
