Key Capabilities / Features

Proofpoint Nexus provides a cohesive experience that brings human-centric protection to end users and security professionals alike, stopping 99.99% of all email threats before they are delivered to inboxes, providing industry-leading efficacy and low false positives. 

With BEC supplier invoicing fraud the leading cause of financial loss for organisations last year, stopping BEC attacks is crucial. Nexus adds a critical layer of defense against advanced email-based attacks. During a BEC attack, a threat actor might impersonate a CEO and request a wire transfer. While the attacker’s message lacks traditional phishing markers, Nexus can still interpret its underlying intent. It understands that there’s an attempt at financial fraud and so it triggers a security alert.

Proofpoint Nexus protects organizations from every angle:

• Nexus Language Model (LM) harnesses advanced AI language models to combat BEC and phishing attacks, by carefully examining email content.

• Generative AI automates complex data analysis across email, cloud and networks using advanced generative algorithms. It identifies subtle variations in patterns, links and content, detecting sophisticated threats.

• Nexus Threat Intelligence (TI) integrates vast amounts of threat data to enhance detection capabilities, providing real-time updates on emerging threats, attacker tactics and vulnerabilities.

• Nexus Relationship Graph (RG) uses behavioral analytics, ML and anomaly detection to spot deviations from normal user actions.

• Nexus Machine Learning (ML) uses advanced ML to fortify threat detection capabilities, employing techniques such as supervised learning, unsupervised learning and ensemble methods.

• Nexus Computer Vision (CV): an AI-powered module designed to identify and neutralize vision-based threats, detecting threats hidden in visual elements, such as phishing sites, QR codes, malicious attachments and spoofed emails.

How we are different

• Unrivaled Data Set: AI and ML require powerful detection models and a high-fidelity data pipeline to yield accurate detection rates, operational efficiencies, and automated protection. Based on Proofpoint’s telemetry, comprised of more than 230,000 global enterprises and small- and medium-sized businesses as well as 150 ISP and mobile network providers, we have an unparalleled view of the tactics, techniques. In fact, Proofpoint analyses more human communications than anyone else – giving Nexus a massive data advantage against competitor solutions. We analyze 3.1T emails, 21T URLS, and 800B attachments per year. This data from various industries and geographies is fed into our Nexus Threat Graph and technologies to learn everything we can about the latest threats and to train models. 

• Unmatched Visibility: Each part of Proofpoint Nexus serves a unique role. It processes vast amounts of data from email, cloud platforms, and collaboration tools to secure all points of communication and interaction. Its modular design covers everything, from stopping threats before they reach users to monitoring risks after delivery - providing unmatched visibility.

Proofpoint protects many of the world’s largest companies and processes billions of emails and tens of billions of URLs daily. Proofpoint was recognized as the overall market leader in the Frost Radar™: Email Security, 2024 report, acknowledging overall market share, growth and innovative leadership and a continued testament to a long-standing commitment to customers’ success. 

• Relentless Innovation: Proofpoint reinvests 20% of annual revenue into R&D – one of the highest rates in the industry - allowing continuous innovation in pace with the threat landscape. An example of this - Proofpoint is currently the only organization placing LLMs inline in the email flow for threat detection.
