Email attacks are getting more and more sophisticated, with offensive AI threatening to supercharge email attack campaigns in the near future. It is becoming almost impossible to distinguish targeted spoof emails from genuine communications.

Novel attacks are consistently getting through traditional email security tools, which observe individual emails in isolation, and compare them against rules and signatures of known malicious attacks. With supply chains becoming more complex and employees more distributed and mobile, the need for an AI-driven, self-learning approach to email security is ever more necessary.

Antigena Email is the world’s first Cyber AI solution for the inbox. By learning the normal ‘pattern of life’ for every user and correspondent, the technology builds an evolving understanding of the ‘human’ within email communications.

While traditional defenses ask whether elements of an email have been observed in historical attacks, Antigena Email is the only solution that can reliably ask whether it would be unusual for a recipient to interact with a given email, in the context of their normal ‘pattern of life’, as well as that of their peers and the wider organization.Inspired by the human immune system, Antigena Email uses Darktrace’s core artificial intelligence to learn a sense of ‘self’ for every internal and external user, analyzing both inbound and outbound communications together with lateral, internal-to-internal communications.

Features

Trusted by thousands of companies
Due to its self-learning approach, Antigena Email works effectively in any email environment, from 10-person charities to multinational corporations with tens of thousands of email users

Understanding the human
Rather than measuring inbound emails against pre-defined rules and signatures, a modern approach to email security uses AI to understand the human beings behind email interactions, learning their typical ‘patterns of life’ in order to spot anomalous behaviour.

A layered AI approach
Darktrace uses a combination of supervised and unsupervised machine learning to detect subtle deviations indicative of a cyber-threat that other tools miss.
