Strongest Layer is an email security platform that uses large language model (LLM) technology to analyze email content and detect threats. The platform reads email messages to identify social engineering attempts, including AI-generated phishing attacks and business email compromise (BEC) schemes. The system operates as an additional security layer that integrates with existing email infrastructure. It performs threat detection by analyzing email content for signs of impersonation, financial fraud, and other social engineering tactics. The platform is designed to identify novel and previously unseen attack patterns that may bypass traditional security tools. Strongest Layer provides threat classification and analysis capabilities to reduce the workload on security teams. The platform includes automated threat detection that aims to minimize false positive alerts. Deployment is designed to be completed within minutes without requiring extensive configuration. The solution targets organizations across various sectors including law firms, manufacturing, technology services, small to medium businesses, and professional services. It focuses on preventing financial loss from email-based attacks and reducing the operational burden on security analysts through automated threat analysis and classification.
