isMalicious Reviews & Product Details

isMalicious is a real-time threat intelligence platform that helps security teams and developers detect malicious IPs, domains, and URLs. It aggregates data from 600+ curated intelligence sources into a database of 500M+ threat records, delivering sub-100ms API responses for production-grade security decisions. Unlike file-focused scanners, isMalicious is purpose-built for IP and domain reputation checking at scale. The unified REST API covers IPs, domains, URLs, email addresses, and file hashes through a single endpoint. Features include a Streaming API for real-time threat feeds (<5s latency), webhooks for event-driven alerting, built-in monitoring with watchlists, and bulk processing for batch operations. isMalicious offers official SDKs for Python, Node.js, Go, and Rust, plus an interactive API playground for testing. It integrates with any SIEM (Splunk, QRadar, Sentinel), SOAR platform, or custom application — no vendor lock-in. Enterprise plans with STIX/TAXII and dedicated infrastructure are available.
