nuMail’s sandboxing component is essential in fully protecting an organization’s email. Sandboxing is a security mechanism for separating running programs, used to execute untrusted or untested programs and code, without risking harm to the host machine or operating system. nuMail utillizes sandboxing to identify zero-day threats in email attachments and email links.

With nuMail, sandboxing also allows for file attachment and in-mail URL analysis with detailed behavioral analysis, monitoring of system activity, exploit efforts, web traffic, subsequent downloads, and communication attempts. nuMail's system is designed to deal with advanced malware that is attempting to avoid detection through VM detection and time bomb techniques.

nuMail integrates with nuSIEM for complete mail flow and threat reporting. The service also includes 24/7/365 Security Operations Center (SOC) and Network Operations Center (NOC) monitoring. Our skilled team of experts and advanced research and development teams are always there for constant review and improvement of algorithms.

nuMail offers enhanced spam detection, improved newsletter classification and delivery control, and excels at identifying image-based spam. Data Leak Prevention (DLP) technology is utilized to detect violations of an organization's content security policy and processes are in place to respond to detected data leaks, such as centralized quarantine review.

This cloud-based service is simple to deploy. A quick change to MX records is all that's needed!
