Proofpoint Nexus® AI models power the Proofpoint human-centric security platform
Proofpoint Nexus® is an ensemble of AI models designed to protect people and defend data across the Proofpoint human-centric security platform. Nexus is designed to mitigate the complex risks people introduce to their organizations, especially in the face of multichannel phishing attacks, malware infiltration, cloud account takeovers and data security challenges such as unauthorized data exfiltration. It continuously analyzes billions of email, web and cloud interactions to detect, prevent and neutralize threats to your people and data before they cause a security incident or breach.
Central to Nexus is its capability to stop human-targeted attacks and human-driven data risks by using multiple AI-driven models from machine learning (ML) to large language models (LLMs). These models are constantly learning from real-world threat research and customer deployments. Nexus gathers intelligence from the tools organizations rely on daily, such as email, collaboration platforms, cloud apps and on-premises data stores.
With the Nexus ensemble of AI models, security teams can rely on adaptive, threat and data-focused intelligence to protect people and defend data. Whether it’s protecting users from cybercriminals, preventing malware, defending data or detecting insider threats, Nexus AI models provide the critical protection needed to secure an organization's most vulnerable entry and data exit points—its people.
Protecting your organization
from every angle
Uncover hidden threats and unknown data risks 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 recognizing subtle linguistic patterns and behavioral 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.
Nexus Language Model (LM) for Data Classifiers is pre-trained to accurately identify sensitive information, such as company intellectual property, discovering information that previously remained hidden and unprotected with unmatched precision.
Automate complex data analysis and streamline 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 unauthorized data exfiltration, that bypass traditional systems. For instance, for data loss prevention (DLP), Nexus Generative AI models process vast amounts of real-time and historical data to detect and prevent sensitive data leaks. Continuously evolving, Nexus accelerates decision-making, neutralizes emerging threats and enhances overall security effectiveness, empowering analysts to respond more efficiently to advanced cyberattacks, insider threats and data loss incidents.
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 behavior to detect insider threats and compromised accounts
Nexus Relationship Graph (RG) uses AI to monitor and assess user behavior, reinforcing cybersecurity defenses. By using behavioral analytics, machine learning and anomaly detection, Nexus RG spots deviations from normal interaction between users that may indicate a potential threat or data risk. Integrating seamlessly with our overall threat detection and data security solutions, Nexus RG enhances real-time defenses, preventing sensitive information from being shared with unintended recipients. This reduces the risk of data leaks, and providing you with comprehensive protection against behavior-driven cyber risks.
Adaptive machine learning provides robust protection against evolving threats and data risks
Nexus Machine Learning (ML) uses advanced machine learning to fortify our threat and data risk 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 risks, providing you with comprehensive protection across multiple cybersecurity areas.
Accelerate data and insider incident response and apply controls with data lineage
Nexus data lineage (DL) uses a highly scalable and flexible Nexus data activity graph to provide end-to-end visibility into data flows for incident response—tracking content from its origin through all manipulations, down to egress channels—and also enables security teams to apply controls based on a file’s location and contextual intelligence.
Neutralize visual deception tactics with advanced vision AI
Nexus Computer Vision (CV) is an AI-powered module designed to identify and neutralize 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.
Orchestrating holistic security to protect people and defend data
Proofpoint Nexus AI achieves its true value through the seamless orchestration of advanced AI, machine learning, behavioral 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 protect people and defend data.
This orchestration ensures that every stage of a potential incident is monitored, analyzed and neutralized in real time, whether it’s blocking phishing attempts or preventing unauthorized data exfiltration, offering unmatched protection.
The real power of Proofpoint Nexus comes from how these models work in concert, transforming individual insights into a unified, multilayered strategy that keeps organizations resilient in an ever-evolving threat landscape.
