What Plan 2 adds to your protection
Three powerful layers that go beyond basic filtering — stopping advanced attacks, keeping your business running, and keeping you compliant.
AI-Based Advanced Threat Protection
Goes far beyond standard spam filters. Uses AI to detect spear phishing, business email compromise (BEC), zero-day exploits, impersonation attempts, and weaponized attachments — in real time, before delivery.
Business Email Continuity
If Microsoft 365 experiences downtime, your users keep sending and receiving email through Hornetsecurity's independent platform — completely transparent, zero disruption, zero lost messages. Your business never stops.
Audit-Proof Email Archiving
Every email your organization sends or receives is stored in tamper-proof, legally compliant archive — searchable in seconds. Built-in eDiscovery, legal hold, and compliance reports keep you audit-ready at all times.
