Complete Perimeter Security
A core component of the Proofpoint Messaging Security Gateway and Proofpoint Protection server software, the Proofpoint Email Firewall provides the SMTP-level, perimeter security features demanded by today's enterprise, creating an impenetrable shield around your messaging systems. Proofpoint's MLX Dynamic Reputation™ technology and SMTP traffic control features work together to protect your network from all types of malicious connections.
MLX Dynamic Reputation and SMTP Traffic Control
Proofpoint MLX Dynamic Reputation technology constantly monitors SMTP connections at the IP address level, looking for suspect or malicious activity. Proofpoint monitors the number of connections, type of activity and content of messages coming from each IP address. Proofpoint MLX machine learning techniques are used to analyze network activity in realtime and assess the risk associated with each connection.
Based on this analysis, Proofpoint takes automatic, corrective action using SMTP traffic control. Malicious connections are automatically blocked or throttled based on fully customizable mail traffic policies.
The Proofpoint Email Firewall provides impenetrable defense against a wide variety of network-level attacks, including Denial of Service, Dictionary and Directory Harvest Attacks, keeping your network and email users safe while preserving network bandwidth. Only Proofpoint offers this dynamic, realtime and self-tuning perimeter security solution.
Secure Messaging and Authentication
The Proofpoint Messaging Security Gateway appliance supports digital certificates and enables gateway-to-gateway secure transfer and receipt of email using Transport Layer Security (TLS). Sensitive information can easily be encrypted for specific domains, business partners or in response to regulatory compliance.
To further ensure the security of encrypted messages, the gateway also supports optional authentication of senders and receivers via TLS.
Proofpoint Protection Server supports server-to-gateway and desktop-to-desktop secure messaging through partnerships with leading secure messaging vendors.
