aDolus FACT Certificate Validation vs Sternum Runtime Protection: 2026 Comparison

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.

Sternum Runtime Protection

Mid-market and enterprise teams protecting IoT and embedded devices in operational technology environments should consider Sternum Runtime Protection if zero-day mitigation without patching is your primary constraint. The EIV binary instrumentation approach delivers memory corruption and code injection prevention at 1–3% CPU overhead, which matters when you can't halt production systems for updates, and the agentless firmware integration avoids the deployment friction that kills most IoT security programs. This tool prioritizes attack prevention and forensics over vulnerability management; if your organization needs vulnerability scanning or patch orchestration, you're looking elsewhere.
