IronMail Edge Appliances
Secure Edge - Applying TrustedSource at the Perimeter
SecureEdge™ is a hardened appliance positioned at the perimeter of the mail system, controlling email traffic at the network border rather than at the mail server or desktop. Edge uses TrustedSource®, Secure Computing's best-in-class reputation system, for information about every sender, to allow or reject email before it even reaches your critical mail servers. Edge provides the following benefits:
- Bad traffic never enters your infrastructure
- Saves on messaging servers' processing time
- Maximizes bandwidth utilization
- Minimizes infrastructure expenses
- Improves overall security
IronMail Edge is positioned between the Mail Gateway and the Internet, providing total protection at the network border. TrustedSource feeds IronMail Edge a constant stream of information about every sender encountered to ensure the most accurate detection of unwanted messages.
Powerful Spam Protection
The global seender profile provided by TrustedSource allows Edge to allow or reject email messages at high speeds, based on a quick IP lookup operation. Edge maximizes speed and efficiency by caching the TrustedSource data locally, with regular updates streamed from the central TrustedSource server. Using the TrustedSource data, Edge can:
- Reject without retry request - When a known bad sender, such as a spammer or hacker, tries to connect, Edge rejects the connection immediately
- Reject with retry request - when a suspicious sender, i.e., one that has either not been previously encountered or has sent bad mail in the past, attempts to connect, Edge will reject the connection, but will ask the suspicious sender to retry
- Allow without connections - messages from "good" senders will pass through the Edge appliance to the email server without any processing
Enterprise Throughput
Edge can protect organizations of any size, with throughput* of up to 3 million email messages per appliance per hour.
* Throughput includes receiving the connection request, performing a TrustedSource query, and handling the message per one of the three actions above.
Failsafe Email Delivery
Edge is interoperable with all existing mail security gateways and mail servers. Additional functionality includes round-robin load balancing and fail-over between next hops for all mail gateways. If all mail gateways are unavailable, Edge will write the messages to disk, and will reattempt delivery intermittently until a mail gateway is available.
Simple Setup and Administration
Edge is easy to install and maintain. The wizard-driven set-up is intuitivev, guiding the administrator through a simple point-and-click interface. Secure Computing advises administrators of exactly which settings will work best in their environment based on current best practices in use by thousands of Secure Computing appliances around the world.
