Sublime Security Sublime Rules
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 detection engineers building custom malware signatures will find Yara-Unprotect valuable for one reason: it gives you pre-built rules for evasion techniques that most commercial tools miss, letting you close gaps without reverse-engineering techniques yourself. The 26 GitHub stars and active maintenance suggest a community actively validating these rules against real samples. Skip this if you're looking for a managed threat hunting platform or automated detection engine; Yara-Unprotect is a reference library that requires you to integrate the rules into your own YARA-capable infrastructure and maintain them as threats evolve.
