AI-Native Email Security Stopping Modern Phishing Threats

StrongestLayer is an AI-native email security platform that detects malicious intent in emails and prevents advanced phishing attacks that bypass traditional security tools. The company’s primary solution is its TRACE engine (Threat Reasoning and AI Correlation Engine), which uses Large Language Models and dual-evidence reasoning architecture to detect phishing threats without relying on signatures, sandboxing, or static rules. The platform analyzes threats across multiple vectors simultaneously, understanding intent rather than just keywords to catch socially engineered threats that traditional filters miss. They have raised $5.2 million.
