HackNotice

HackNotice is an external threat-intelligence and cyber-risk platform founded in 2018 and headquartered in Austin, Texas. It continuously collects intelligence from ransomware groups, infostealer malware logs, data breaches, dark-web marketplaces, hacker forums and public disclosures, then matches that intelligence against the domains, employees, customers and vendors an organization asks it to watch. The product is organized around four monitoring services — first-party domain monitoring, third-party vendor risk monitoring, end-user credential monitoring, and threat research and investigations — plus AI-assisted vendor security assessments. HackNotice exposes this surface programmatically through a REST API documented as a public Postman collection at api-docs.hacknotice.com, a remote Model Context Protocol server at mcp.hacknotice.com whose tool catalogue answers anonymously, first-party n8n automation nodes on npm, and webhook, Splunk HEC and SIEM/SOAR alert delivery.

HackNotice publishes 1 API on the APIs.io network. Tagged areas include Company, Security, Threat Intelligence, Cybersecurity, and Dark Web Monitoring.

The HackNotice catalog on APIs.io includes 1 event-driven AsyncAPI specification.

HackNotice’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 27 more developer resources.
