What is Proofpoint Nexus®?
The Detection Behind
Human-Centric Security

Intro

Proofpoint Nexus® powers comprehensive human-centric protection


Proofpoint Nexus® is a comprehensive threat intelligence platform powered by AI,
machine learning and real-time threat intelligence. Nexus is designed to mitigate the complex risks people introduce to their organisations, especially in the face of rising phishing attacks, malware infiltration and cloud account takeovers. It continuously analyses billions of email, web and cloud interactions to detect, prevent and neutralise these threats before they compromise your data and systems.

Central to Nexus is its capability to stop human-targeted attacks by using multiple AI-driven model types. This advanced defense system is constantly learning from real-world threat research and integrates seamlessly with the tools organisations rely on daily, such as email, collaboration platforms and cloud apps.

With Nexus threat intelligence platform, security teams can rely on adaptive, threat-focused solutions that stay ahead of evolving cybercriminal tactics. Whether it’s protecting users from phishing, detecting insider threats or preventing malware, Nexus provides the critical protection needed to secure an organisation's most vulnerable entry points—its people.

How it Works

Protecting your organisation from every angle

Uncover hidden threats through advanced language analysis

Nexus Language Model (LM) for BEC harnesses the power of advanced AI language models to combat business email compromise (BEC). It carefully examines email content to detect common elements found in BEC attempts, such as transactional language and urgency. By recognising subtle linguistic patterns and behavioural cues, Nexus LM for BEC identifies suspicious emails before they can cause harm. This cutting-edge solution adds a critical layer of defense, offering superior protection against sophisticated email-based attacks.

Automate complex data analysis and streamline threat detection

Generative AI automates complex data analysis across email, cloud platforms and networks using advanced generative algorithms. Instead of relying on predefined rules, it identifies subtle variations in patterns, links and content, detecting sophisticated threats, such as phishing attempts and unauthorised data exfiltration, that bypass traditional systems. For instance, in data loss prevention (DLP), Generative AI processes vast amounts of real-time and historical data to detect and prevent sensitive data leaks. Continuously evolving, it accelerates decision-making, neutralises emerging threats, and enhances overall security effectiveness, empowering analysts to respond more efficiently to advanced cyberattacks.

Use real-time global threat data to stay ahead of cybercriminals

Nexus Threat Intelligence (TI) integrates vast amounts of threat data to enhance detection capabilities across Proofpoint products. It provides real-time updates on emerging threats, attacker tactics and system vulnerabilities. With its focus on advanced threat intelligence, Nexus TI ensures Proofpoint solutions stay ahead of evolving cyberthreats, offering proactive detection and defense. This system is key to maintaining a resilient security posture against modern cyber adversaries.

Identify anomalous user behaviour to detect insider threats and compromised accounts 

Nexus Relationship Graph (RG) uses AI to monitor and assess user behaviour, reinforcing cybersecurity defenses. By using behavioural analytics, machine learning and anomaly detection, Nexus RG spots deviations from normal user actions that may indicate a potential threat. Integrating seamlessly with our overall threat detection systems, Nexus RG enhances real-time defenses, providing you with comprehensive protection against behaviour-driven cyber risks. 

Adaptive machine learning provides robust protection against evolving threats

Nexus Machine Learning (ML) uses advanced machine learning to fortify our threat detection capabilities. By employing techniques such as supervised learning, unsupervised learning and ensemble methods, Nexus ML provides scalable and robust security solutions. This core AI technology ensures Proofpoint can detect and mitigate a wide range of evolving threats, providing you with comprehensive protection across multiple cybersecurity areas.

Neutralise visual deception tactics with Advanced Vision AI

Nexus Computer Vision (CV) is an AI-powered module designed to identify and neutralise vision-based threats. Through advanced computer vision technology, Nexus CV detects threats hidden in visual elements, such as phishing sites, QR codes, malicious attachments and spoofed emails. By focusing on visual threat vectors, this module enhances security by providing you with a powerful response to attacks that involve embedded images and other graphical content.

In Action

Orchestrating holistic security to protect people and defend data

Proofpoint Nexus threat intelligence platform achieves its true value through the seamless orchestration of advanced AI, machine learning, behavioural analysis, threat intelligence and visual threat detection. By integrating these diverse methods into a cohesive system, Proofpoint Nexus provides a powerful, adaptive defense that dynamically responds to emerging threats.

This orchestration ensures that every stage of an attack is monitored, analysed and neutralised in real time, offering unmatched protection. The real power of Proofpoint Nexus comes from how these components work in concert, transforming individual insights into a unified, multilayered strategy that keeps organisations resilient in an ever-evolving threat landscape.
