Security
Enterprise-grade security built into every layer of Linea.
Security-first email infrastructure
Linea is built to protect both the message and the business behind it. We combine Linea Email Guard (our in-house agent) with partner integrations to deliver layered protection and enterprise control.
Threat Protection
Advanced spam, phishing and malware detection across inbound and outbound mail, with quarantines and admin review.
Policy & Governance
Domain-level policies, content rules, DLP hooks, and admin-managed compliance presets.

TLS for transport, optional at-rest encryption and integrations for managed key stores.
Access & Identity
Role-based access control, SAML/SSO, and audit logs to meet enterprise identity requirements.
Monitoring & Incident Response
Real-time monitoring, alerting, and an incident workflow to investigate and remediate threats quickly.
Extensible Integrations
Route messages through existing security stacks or connect partner scanners for deeper analysis.
