cti-python-stix2 is a free threat intelligence platforms tool. Lunar is a free threat intelligence platforms tool by Webz.io. Compare features, ratings, integrations, and community reviews side by side to find the best threat intelligence platforms fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Threat intelligence teams who need to ingest, transform, and share STIX2 data across internal tools should use cti-python-stix2 to avoid vendor lock-in and reduce integration friction. The library handles JSON serialization natively with 398 GitHub stars and zero licensing costs, making it the fastest path to STIX2 compliance for teams already Python-native. Skip this if your analysts expect a UI or expect the tool to do threat hunting; it's a developer dependency, not an analyst platform.
Security teams managing breach aftermath and credential exposure across multiple domains should adopt Lunar for its real-time infostealer log intelligence, which surfaces compromised credentials faster than waiting for breach notifications. The platform ingests large-scale daily breach data and prioritizes service-level context for remediation, directly supporting the NIST Detect function of continuous monitoring and incident characterization. Skip this if you need post-compromise forensics or threat hunting beyond credential validation; Lunar is detection and alerting first, not investigation.
