You can configure the integration of Kaspersky Secure Mail Gateway with Kaspersky Anti Targeted Attack Platform.
Kaspersky Anti Targeted Attack Platform (KATA) (hereinafter also referred to as "the program") is a solution designed for the protection of a corporate IT infrastructure and timely detection of threats such as zero-day attacks, targeted attacks, and complex targeted attacks known as advanced persistent threats (hereinafter also referred to as "APT").
After its integration, Kaspersky Secure Mail Gateway will be able to send email messages to Kaspersky Anti Targeted Attack Platform for scanning and receive the scan results. KATA scans messages for signs of targeted attacks and intrusions into the corporate IT infrastructure.
Based on the results of a KATA scan, Kaspersky Secure Mail Gateway can block individual messages.
