Core Features
Everything in Plan 1
Three pillars of email security that work together to protect every message your organization sends and receives.
Spam & Malware Protection
Multi-layer AI engine scans every inbound and outbound email in real time — blocking spam, viruses, ransomware, and malicious attachments before they ever reach an inbox. Updated continuously against zero-day threats.
Automated Email Encryption
Sensitive outbound emails are automatically encrypted based on policy rules — no manual steps required, no special software needed for recipients. Supports S/MIME, PGP, and TLS. Fully compliant with GDPR and industry regulations.
Email Signatures & Disclaimers
Centrally apply consistent, on-brand email signatures and legal disclaimers across every user in your organization — regardless of device, client, or location. Manage everything from a single admin dashboard.
Inbound & Outbound Filtering
Every email flowing in or out of your domain passes through our security engine — inspecting content, attachments, links, and sender reputation to block threats and prevent data leaks in both directions.
Real-Time Threat Dashboard
A live overview of all threats detected, blocked, and quarantined across your organization. See trends, drill into individual incidents, and generate compliance-ready reports with one click.
Admin & User Portal
Administrators get full control over policies, quarantine management, and reporting. End users get a self-service portal to review their own spam quarantine and adjust preferences — without involving IT.
