Recognized as a Leader in Gartner’s Magic Quadrant and Leaders in the 2025 Voice of the Customer award for Email Security Platforms, it is designed to address the growing sophistication of communication-based attacks. Traditional secure email gateways often rely on static rules or signatures, which struggle against modern threats such as business email compromise and supply chain attacks. Darktrace / EMAIL takes a different approach by using Self-Learning AI to understand the unique communication patterns of each organization and user. This allows it to detect subtle anomalies across inbound, outbound, and lateral messages, and respond with precise, autonomous actions. Key capabilities include: - Behavioral threat detection: Identifies phishing, ransomware, account takeovers, and insider risks by learning “normal” communication behavior of internal and external users. - Protection beyond the inbox: Extends security to collaboration platforms like Microsoft Teams and SaaS applications, addressing the shift of phishing into new channels. - Adaptive response: Suspicious emails are automatically quarantined, links are rewritten, or attachments are removed, all without interrupting legitimate business communication. This approach enforces regular communication and ensures that as much safe, non-malicious content as possible is retained. - Data protection: Provides behavioral data loss prevention and assists with your DMARC configuration and monitoring to safeguard sensitive information and brand reputation. For security teams, Darktrace / EMAIL reduces operational overhead by automating triage and response. Its Cyber AI Analyst provides contextual insights, while end-users benefit from clear, in-app narratives that explain why a message is suspicious—helping to reduce false phishing reports and improve awareness. Benefits for organizations include: - Comprehensive coverage across email, collaboration, and SaaS platforms. - Reduced workload for security teams through automation and AI-driven analysis. - Seamless integration with Microsoft 365, Exchange, and Google Workspace without disrupting mail flow. In summary, Darktrace / EMAIL delivers adaptive, AI-driven protection across the full communication ecosystem. Its dual recognition as a Gartner Leader in both the Voice of the Customer award and the Magic Quadrant for Email Security Platforms in 2025 highlights its effectiveness in helping organizations defend against today’s most complex and fast-evolving threats.
