VirusTotal is generally regarded as a reliable source for threat intelligence and offers both free and paid services. The VirusTotal plugin supports enriching URLs, files, hashes, IP addresses, and domains with threat intelligence provided by VirusTotal.
To create a VirusTotal connection, you will only need a user API key from VirusTotal. This document explains how to configure a free VirusTotal account for use with InsightConnect.
VirusTotal Public API constraints
The VirusTotal Public API is a cost-free threat intelligence service that is rate-limited. The Public API (as of 5/27/2021) is limited to 500 requests per day and a rate of 4 requests per minute. See VirusTotal's API documentation for more information.
