451 Research: Tessian Uses Machine Learning for Better DLP

  • 11 May 2020

According to a new report from 451 Research, “the DLP market is ripe for change” and Tessian could be the next-generation solution organizations need to detect and prevent both inbound email attacks and outbound email threats

Key findings from the report include:

“While [most existing DLP tools] are good at finding personally identifiable information (PII), finding and blocking actions such as employees sending files to a personal email account are surprisingly challenging and are quickly out-of-date, so predefined rules are not that effective.”
Garrett Bekker, 451 Research

DLP: An Unsolvable Problem

While the DLP market is saturated with products – from traditional DLP vendors like Broadcom, McAfee, Forcepoint, and Digital Guardian to newer entrants like ArmorBlox, Altitude Networks, and Code42, the consensus is that DLP is, in many ways, failing.

According to the report, “DLP technology has developed a reputation as much for inaccuracy, false positives, and poor performance as it has for protecting data.”

That may be why DLP remains one of the top spending priorities for IT leaders, with 13% of those surveyed by 451 Research saying they expect to see a “significant increase” in spending over the next 12 months and a further 11% saying they expect to see a “slight increase.” It’s clear organizations need a better way to prevent data loss. 

Tessian believes it’s because DLP efforts aren’t addressing the real problem, which is that 88% of data breaches are caused by human error.  

Tessian’s Approach to Data Loss Prevention

Instead of focusing on the machine layer, Tessian focuses on the human layer and, in doing so, has developed the world’s first Human Layer Security platform.

  • What is Human Layer Security?

    Human Layer Security (HLS) is technology that secures all human-digital interactions in the workplace. By focusing on the human layer (employees, contractors, customers, suppliers) as opposed to the machine and systems layer (networks, devices, apps), HLS keeps business’ sensitive data and systems safe without impeding employee productivity.

Our Human Layer Security platform consists of four main products: Tessian Defender, which prevents advanced inbound attacks like spear phishing, Tessian Guardian, which prevents accidental data loss caused by misdirected emails, Tessian Enforcer, which prevents data exfiltration attempts on email. Organizations that implement any of these solutions also get Tessian Constructor, which allows admins to create blacklists, whitelists, and custom filters to ensure email usage remains compliant. 

Each of these products applies stateful machine learning techniques to historical email messages (headers, body, and attachments) to understand relationships and establish normal behavior profiles that can be used to distinguish between safe and unsafe emails.  No rules required.

According to 451 Research, Tessian succeeds in preventing data loss where others fall short.
