SECURITY

CONTINUITY
Emergency Inbox: This provides end-user access to email in the event of an email service outage. It is activated instantly and automatically upon detection of an outage, and users can open, read, download attachments and reply to any email queuing.
Instant Replay: With the Essentials Instant Replay feature, end users can easily replay successfully delivered emails received in the last 30-days that may have been wrongly deleted or accidentally removed from servers.
Email Spooling: Email spooling and failover provides a comprehensive, extremely low-maintenance answer to your backup MX management needs. It preserves email metadata during an outage and delivers quick restoration of SMTP traffic to the primary site once recovery is detected.
ARCHIVING
Archiving: Proofpoint email archiving helps to eliminate data storage constraints and meet legal and regulatory obligations with a 10-year cloud archive, which ensures organizations stay protected and compliant. The service features real-time envelope journaling for local Exchange and Office 365 and unlimited storage
Search and Discovery: The Essentials email archive comes with advance search capabilities for the super-fast and easy retrieval of specific emails and attachments. This fully-hosted solution features world-class search and legal discovery, configurable retention policies, and an easy-to-use search archive audit log.

Proofpoint Essentials has advanced reporting capabilities and administrative controls like multi-level logins, domain management, comprehensive and instant log search, and Active Directory sync for Microsoft Exchange and Microsoft Azure.
