Carrier-Grade Performance

From enterprises to the world's largest free email systems, it has a proven high level of performance, reliability and scalability. Its results have come from many years of experience of dealing with large-scale global telecommunications carriers. Cloudmark's service can manage transmission and reception whilst processing emails at exceptional speeds by optimizing network-wide delivery.

Advanced Control of Email Traffic

The email server was developed and designed to meet the stringent requirements of enterprises, public institutions and telecommunications carriers. It is therefore able to handle delivery control, bandwidth limitation and other complex requirements which are a challenge for open-source email servers.

Traffic Visualization and External Data Links

Cloudmark engineers are familiar with the difficulties of operating an email system. Thus, they provide statistical dashboards which help administrators to understand mail traffic, any threats and the movement of the system. The system can also support many APIs that can link to various databases including subscriber information, employee details and streamlines unnecessary operational procedures.

Flexible Operational Policy Control

Through Cloudmark's powerful and flexible workflow-type operations policy engine both allowed content and blocked content can be controlled.
