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 working with limited budgets should start with yarGen; it generates tuned YARA rules from actual malware samples faster than writing them manually, and the 1,781 GitHub stars reflect active use in incident response workflows. The tool excels at reducing false positives by automatically stripping goodware strings, which matters when you're operationalizing detections across thousands of endpoints. Skip this if you need a point-and-click GUI or rules validated against known-good binaries; yarGen assumes command-line comfort and requires manual vetting of output before deployment.
