Raven Email Threat Detection

Raven Email Threat Detection is a cloud-native email security software for Google Workspace and Microsoft 365. Built using large language models (LLMs), Raven goes beyond traditional secure email gateways (SEGs) by detecting advanced, identity-based threats like phishing, business email compromise (BEC), vendor impersonation, and thread hijacking — even when standard trust signals like SPF/DKIM/DMARC pass. Raven’s AI-native engine analyzes email content, sender-recipient context, behavioral baselines, and infrastructure signals to surface threats that legacy tools miss. It detects credential phishing, impersonation, and invoice fraud without relying on static rules or keyword matching, ensuring high detection efficacy with low false positives. What sets Raven apart is its built-in vendor risk detection engine — an industry-first capability. Raven automatically fingerprints vendor invoices, flags suspicious changes in bank account details, monitors email and web infrastructure for compromised third-party tools, and detects spoofed or unauthorized senders in conversation threads. This enables companies to stop supply chain attacks, which are increasingly the root cause of financial and reputational losses. Deployed through secure APIs, Raven integrates natively into Microsoft 365 and Google Workspace in under 10 minutes — with no MX record changes required. Raven can complement or replace traditional tools like Proofpoint, Mimecast, Cisco IronPort, or Microsoft Defender, offering post-delivery remediation capabilities such as inbox pullback, domain blocking, and RBAC-governed investigations. Raven is fully ISO 27001 and SOC 2 compliant, with support for privacy and compliance use cases across regulated industries including financial services, healthcare, manufacturing, and SaaS. Key use cases: Detect phishing and BEC attacks with LLM-powered email threat protection Stop vendor-origin threats using invoice fingerprinting and domain monitoring Identify lookalike domains, thread hijacks, and insider risks Enable real-time remediation and insights without disrupting mail flow Integrate with SIEMs and GRC platforms for centralized response Raven is ideal for security teams that need modern, AI-driven email protection that evolves with emerging attacker techniques — especially where email security software must balance contextual intelligence, low false positives, and fast deployment.
