Based on our analysis of core features, here is our conclusion:
Security teams running Microsoft 365 or Google Workspace who need to stop BEC and credential phishing without adding another paid platform should start with Sublime Security Sublime Rules. The detection logic is built on Message Query Language rules that actually catch HTML smuggling and OneNote malware where signature-based filters fail, and you get DLP discovery rules included at zero cost. Skip this if your org needs automated response or investigation workflows; Sublime Rules is detection-only and assumes you have a process to act on what it finds.
Threat hunters and malware analysts who need to quickly build custom file detection rules without vendor lock-in should use Yara Rules by Malgamy as a starting reference library. The 66 GitHub stars and active community contributions signal real adoption among practitioners, though you'll spend time refining and testing rules for your specific environment rather than deploying them as-is. Skip this if you need a managed rules service with threat intelligence updates; Malgamy is a static collection that demands your own operational overhead to stay current.
