aDolus FACT - Malware Detection vs Arya - The Reverse YARA: Side-by-Side Comparison (2026)

aDolus FACT - Malware Detection

Mid-market and enterprise teams managing software supply chains will get the most from aDolus FACT because it consolidates multiple antivirus engines and YARA rules into a single malware detection workflow, catching threats that isolated scanners miss. The tool maps component relationships to identify hidden infection paths, and covers NIST GV.SC (supply chain risk management) and DE.AE (adverse event analysis) with actual depth rather than surface-level compliance. Skip this if you need post-infection response or threat hunting; FACT stops at detection and doesn't help you understand how malware moved through your network after the fact.

Arya - The Reverse YARA

Red team operators and detection engineers validating YARA rules need Arya - The Reverse YARA to generate test files that actually trigger their signatures without running live malware. The free pricing and 258 GitHub stars reflect active adoption by practitioners who need fast iteration on rule tuning, not theoretical validation. Skip this if your team writes rules infrequently or lacks the technical depth to interpret false positives; Arya assumes you already know what your rules should catch and just need proof they work.
