Show HN: VerdictMail – IMAP daemon that uses LLM reasoning to catch phishing (github.com)

VerdictMail, an AI-driven email threat analysis daemon, has been introduced to enhance security for Gmail users. It utilizes IMAP IDLE for real-time monitoring, automatically analyzing incoming emails through a sophisticated multi-stage pipeline that includes parsing, enrichment with domain reputation checks like SPF and DKIM, and AI evaluation leveraging services such as OpenAI and Anthropic. The system's decision-making is robust, allowing it to either pass, flag, or move suspicious messages to Junk based on threat levels determined by AI confidence thresholds. This development is significant for the AI/ML community as it exemplifies the practical application of large language models (LLMs) in cybersecurity, particularly in combating phishing attacks. By streamlining the email vetting process through automation and machine learning, VerdictMail not only promotes safer email environments but also showcases an innovative approach to integrating AI with existing IT infrastructures. Its detailed audit log feature adds transparency to the decision-making process, providing users crucial insights into threat detection and response, which is essential for ongoing improvements in AI-algorithm effectiveness.
