Product Overview: Darktrace Antigena Email
Introduction
Darktrace Antigena Email is a cutting-edge, AI-powered email security solution designed to detect and neutralize sophisticated cyber threats, including phishing, spear phishing, and other malicious email attacks. This technology is part of Darktrace’s broader Enterprise Immune System, which leverages machine learning and autonomous response capabilities to protect organizations from evolving cyber threats.
Key Features and Functionality
Advanced Threat Detection
- Antigena Email analyzes emails based on a comprehensive understanding of the organization’s ‘patterns of life,’ incorporating data from network, cloud, and email environments. This holistic approach allows the system to identify subtle anomalies that may indicate malicious activity, even if the emails appear benign at first glance.
Autonomous Response
- Unlike traditional Secure Email Gateways (SEGs) that process emails only once, Antigena Email continuously re-assesses emails multiple times, even after delivery. This real-time monitoring enables the system to take proportionate and targeted actions to neutralize threats as new evidence emerges.
Contextual Analysis
- The system evaluates various elements of an email, including links, attachments, domains, content, and sender information. It correlates this data with historical sending patterns, network activity, and the broader business context to determine whether an email is malicious. For example, it can detect unusual IP addresses, rare domains, and inconsistent link behaviors.
Dynamic and Adaptive
- Antigena Email adapts to evolving behavioral patterns autonomously, distinguishing between benign and malicious emails based on the organization’s unique communication norms. This self-learning capability ensures that the system remains effective against novel and creative attack techniques.
Surgical Actions
- When a threat is identified, Antigena Email responds autonomously and proportionately, ensuring minimal disruption to legitimate email traffic. It can lock suspicious links, remove malicious emails from inboxes, and enforce the normal ‘pattern of life’ of the digital environment without interrupting business operations.
Comprehensive Protection
- Antigena Email protects against a wide range of threats, including spear phishing, social engineering, supply chain risks, and advanced payload delivery. It also recognizes and reacts to external account takeovers of trusted contacts and other sophisticated email-based attacks.
User and Organizational Insights
- The system provides a dedicated dashboard for operators to gain oversight of their email risk profile and trends over time. This includes metrics on which users are most exposed and how the organization may be at risk, helping to inform and enhance the overall security posture.
Handling Unusual but Benign Emails
- Antigena Email is designed to handle emails from new contacts that are unusual but non-threatening. It uses its understanding of employees’ communication patterns to differentiate between anomalous but benign emails and genuinely malicious ones, ensuring that legitimate communications are not disrupted.
Benefits
- Enhanced Security: Provides unparalleled detection and response capabilities against advanced email threats.
- Minimal Disruption: Ensures business operations continue uninterrupted by taking surgical and proportionate actions.
- Autonomous Protection: Operates 24/7, responding to threats in real-time, even when security teams are not available.
- Reduced Administrative Workload: Automates the process of distinguishing between benign and malicious emails, significantly reducing the administrative burden.
In summary, Darktrace Antigena Email is a robust and intelligent email security solution that leverages AI and autonomous response to protect organizations from sophisticated cyber threats, ensuring continuous and secure email communication.
