aDolus FACT Certificate Validation vs Darktrace OT: 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.

Darktrace OT

Mid-market and enterprise teams protecting OT environments should choose Darktrace OT for its self-learning AI that catches zero-day attacks without requiring signature updates or manual tuning. The platform covers the full detection-to-response chain across Purdue Model levels, with automated incident investigation through Cyber AI Analyst and configurable autonomous response that actually executes without human approval. Skip this if your organization needs mature incident recovery workflows; Darktrace prioritizes detecting and stopping threats in real time over post-incident forensics and recovery guidance.
