aDolus FACT Certificate Validation vs Rhebo OT Security: 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.

Rhebo OT Security

Mid-market and enterprise manufacturers with fragmented OT networks need Rhebo OT Security for anomaly detection that actually works across legacy and modern ICS environments without requiring full network redesign. The platform discovers and monitors assets in-place while flagging both cyberattacks and operational faults through MITRE ATT&CK for ICS patterns, which matters because most OT teams can't distinguish between a breach and a misconfiguration until it's too late. Skip this if your priority is IT/OT convergence or you need tight integration with your SOC's existing EDR stack; Rhebo prioritizes OT detection and isolation over incident response orchestration.
