In their own words
FullHunt
FullHunt provides internet intelligence for security products and external attack surface monitoring, through web access, APIs, data feeds, and MCP. It discovers internet-facing domains, subdomains, IPs, cloud services, ports, technologies, and certificates. Continuous monitoring follows new assets, service and certificate changes, configuration drift, and exposure alerts. Its vulnerability intelligence links CVEs to observed assets with exploit context, EPSS scores, and CISA KEV status. Enterprise workflows also cover compromised credentials, infostealer activity, typosquatting, and phishing infrastructure tied to monitored organizations. Listed integrations include security platforms, ticketing systems, and collaboration tools such as Splunk, Jira, Slack, and Microsoft Teams. Developers can use REST APIs, a Python SDK, and MCP tools; API requests use credits that reset monthly. Plans range from a free option with 10 credits per month to paid plans from $149 a month. A 14-day trial is listed for qualified Enterprise organizations. Users must have lawful authority to monitor submitted assets and use the service for legitimate cybersecurity purposes.
