DoubleCheck Product Overview

DoubleCheck helps you better manage and secure your email using the following features and tools:

  • Anti-Spam Engine

  • Anti-Virus Engine

  • Anti-Phishing Engine (v4.2)

  • Policy/Content Filtering Engine

  • SMTP Management

  • Recipient Verification with LDAP Integration (v4.2)

  • Logging and Reporting

  • Inbound and Outbound Scanning

Solutions are available for two user levels:

  • "1-250 Users" - For up to 250 users. Available in tower, rack and software-only configurations.
  • "250+ Users" - Available in tower, rack and software-only configurations.
  • "ASP/Hosted Services" - Available based on the configuration and offering of our Authorized DoubleCheck Resellers.

Systems are generously licensed by "email users," those individuals who send and receive email. You do not need to count reasonable aliases such as "sales@" or "info@."

Systems are sized by throughput. In general, tower systems process an average of 1,250 queue messages per hour, while rack systems process 2,000 queue messages per hour. These numbers do not include spam and can spike to 50% more on occasion. Please contact eFolder or an Authorized DoubleCheck Reseller for sizing specifics.

The software-only version of DoubleCheck installs on 3rd-party hardware, converting the system into an "appliance." The installation includes the operating system and all components of DoubleCheck.

Additionally, DoubleCheck is available as an ASP/Hosted solution for businesses that host mail for multiple organizations or who do not want to install the email appliance. Contact eFolder or an Authorized DoubleCheck Reseller for details.

Each solution offers an inexpensive way to add layered security to your network and email users. Justification and ROI calculations are straightforward. Technical support is available through an
Annual Maintenance Contract.

The DoubleCheck Email Manager is typically installed between the firewall and the email server (see Fig. 1 below). Incoming email is either blocked, tagged, quarantined, deleted, rejected or delivered cleanly to users. (see Fig. 2 below)

DoubleCheck's Admin Console is easy to setup and configure, in addition to leveraging powerful monitoring and logging tools for reporting.
