aDolus FACT Certificate Validation vs Gyala Agger: Side-by-Side Comparison (2026)

aDolus FACT Certificate Validation

Security teams protecting ICS/OT environments should use aDolus FACT Certificate Validation to detect fraudulent and stolen code signing certificates before malicious firmware reaches operational technology assets. The tool validates certificate chains and authenticates unsigned binaries across ICS software and firmware, addressing GV.SC supply chain risk management where most validation tools assume standard software distribution channels. Skip this if your organization runs primarily Windows/Linux endpoints in IT networks; the value concentrates in OT shops where firmware provenance verification is non-negotiable and certificate spoofing creates physical safety risk.

Gyala Agger

Mid-market and enterprise operations teams defending both IT and OT environments need Gyala Agger because it actually sees legacy and air-gapped networks that mainstream EDR platforms ignore. Its behavioral anomaly detection runs on operational state models rather than signature patterns, which matters when you're protecting systems that can't be patched or rebooted. The caveat: Gyala prioritizes detection and response speed over the forensics and recovery depth that mature SOCs demand; if your incident response workflow depends on weeks of historical correlation and root cause analysis, you'll outgrow this tool quickly.
