Libraesva Email Security

What it does

Libraesva Email Security is a Secure Email Gateway (SEG) that inspects inbound and outbound mail before delivery to defend against phishing, business email compromise (BEC), malware, and spam. Its distinguishing approach is local processing: attachments are detonated and links analyzed inside a self-contained sandbox on the gateway rather than being shared with external clouds. An Adaptive Trust engine models each organization's normal sender and communication patterns to flag anomalies and impersonation.

How it works

Deployed by pointing a domain's MX record at the gateway, it routes all inbound mail through layered filters: anti-spam and sender-reputation checks, QuickSand attachment sandboxing that disarms Microsoft Office and PDF files locally, and URLSand link rewriting that re-scans each destination in a sandbox at the moment a user clicks. Semantic and Adaptive Trust models add intent and anomaly analysis without sending content to third parties. Outbound mail passes data loss prevention, policy-based encryption, and account-takeover controls that adjust SMTP sending limits from historical patterns. It runs in front of Microsoft 365 and Google Workspace mailboxes.
