Platform Capabilities
Enterprise-grade security, without the enterprise overhead
Every tier shares the same core engine. More aggressive policies and deeper analytics unlock at higher tiers.
Multi-Layer Threat Detection
Heuristic scoring, DNSBL, greylisting, and reputation-based filtering combine in a single-pass pipeline that stops threats before your MX server even sees them.
Real-Time Mail Flow Analytics
Per-domain dashboards with live message traces, threat breakdowns, and 7-year log retention. Know exactly what your gateway is doing at every moment.
Granular Policy Engine
Unlimited custom rules with header inspection, content matching, and per-sender overrides. Policy changes propagate in under 30 seconds globally.
Self-Service Quarantine
End users release their own held messages without helpdesk involvement. Configurable daily digests reduce admin load by up to 80%.
Enforced TLS 1.3
Mandatory and opportunistic TLS on all paths, configurable per domain. Full certificate validation with audit trail for compliance requirements.
Multi-Domain Management
Add domains in seconds. Each gets isolated policies, quarantine stores, and reporting. Multi-tenant architecture built for MSPs and enterprises.
