Libraesva Email Security is a security gateway that uses a layered defense system to identify and block threats before they reach the user's inbox. It is designed for businesses across various sectors, including financial services, healthcare, and manufacturing, that need to defend against AI-generated phishing and impersonation attacks.
The tool uses a combination of Semantic AI to analyze intent and Adaptive Trust AI to identify behavioral anomalies. The system uses small language models (SLMs) that run locally on the business's own hardware or private cloud, which supports a workflow where email data is not sent to external cloud LLMs for analysis.
Beyond threat blocking, the platform supports standard email authentication protocols. Buyers should confirm their preference for on-premise or cloud deployment and verify if the 30-day trial is sufficient to test the local processing performance on their hardware.
