- Flexible architecture that allows for a faster reaction to new types of malware
- Minimal impact on throughput due to low resource consumption
- Less disc space required than leading competitors
- Small SDK footprint
Integrated CYREN Virus Outbreak Detection
- Closes the gap between a virus outbreak and definition updates

- Immediate threat detection
- Requires no signatures – leverages Recurrent Pattern Detection technology
Designed as a Gateway
A mail gateway is a server that is set up in front of your organization’s primary mail server, and serves as a buffer for the internal mail server against the hazards of the internet.
Using IMail Secure Server can serve numerous possible purposes:
- To process and filter all incoming mail before it is passed on to the internal mail server that delivers the messages. This can include spam and virus filtering, along with other types of filtering as discussed further below.
- To reduce the amount of traffic to your primary mail server.
- To enhance security on your network. An e-mail gateway provides a barrier between your internal network and the internet. Set up correctly, a gateway minimizes the access to your internal network should it ever become compromised.
