RST Cloud - Threat Feed API

This Integration is part of the RST Threat Feed Pack.#

Supported versions

Available on Cortex XSOAR (versions 6.0.0 and later) and Cortex XSIAM.

This is the RST Threat Feed integration for interacting with API This integration was integrated and tested with RST Cloud - Threat Feed API v1

Please contact the RST Cloud team via email support@rstcloud.net to obtain a key and ask any questions you have. Also, the following contact details can be used:

URL: https://www.rstcloud.net/contact

Each indicator is ranked from 0 to 100. Indicators are being collected from multiple sources and are cross-verified using multiple criteria. Please check indicator tags and malware family fields. An indicator may describe a known malware or a scanning host. Therefore, different actions may be required based on the context.
