aDolus FACT Certificate Validation vs Cynalytica OT OptICS™: 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.

Cynalytica OT OptICS™

Enterprise and mid-market operations teams with serial-connected legacy ICS will find Cynalytica OT OptICS™ invaluable because it requires no manual rulesets to detect anomalies, meaning you avoid the months-long tuning cycle that kills most ICS deployments. The machine learning baseline covers RS-232/485/422 networks without protocol-specific configuration, and the 24/7 managed monitoring service means your skeleton OT staff actually sleep. Skip this if your environment is primarily Ethernet-native Modbus TCP or Profinet; OptICS™ is built for the serial-connected level 0 and 1 devices that most tools ignore, which is both its strength and its scope limitation.
