What Libraesva Email Security is
Libraesva Email Security provides layered, AI-driven protection against email threats for organizations. Its Semantic AI examines email meaning and intent to flag deception, with processing performed locally. Adaptive Trust AI learns an organization’s communication patterns to identify anomalies and does not train on customer content. For attachments, the product uses an isolated sandbox inside the customer’s environment; active URL analysis checks link paths without sharing link data externally or depending on third-party APIs. Automatic Account Takeover Protection adjusts outbound SMTP quotas and limits according to historical sending patterns. The product supports outbound filtering and impersonation protection, and identifies Microsoft 365 and Gmail among supported email services. Deployment is hybrid, with self-hosted and web platforms; trial deployment choices include On Premise and Private Cloud. Pricing is available on request, based on a form that asks for approximate mailbox count and deployment. There is no free plan, but a free 30-day trial is offered. Libraesva says it has helped businesses secure email since 2013.
