GRASSMARLIN vs Redpoint: 2026 Comparison
GRASSMARLIN is a free operational technology asset discovery tool. Redpoint is a free operational technology asset discovery tool. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology asset discovery fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Operations teams defending critical infrastructure without dedicated ICS/SCADA visibility should start with GRASSMARLIN; its passive network mapping gives you topology sight-lines without touching production systems, which matters when downtime costs six figures per hour. The tool is free and runs on commodity hardware, so deployment friction is nearly zero for teams of any size. The tradeoff is real: GRASSMARLIN maps what exists but doesn't actively hunt for misconfigurations or lateral movement, so it's a foundation layer, not a standalone defense.
OT security teams responsible for brownfield industrial environments should start with Redpoint because it's free and built specifically to enumerate ICS applications that commercial asset discovery tools consistently miss. Digital Bond's research pedigree means the detection signatures actually reflect how legacy SCADA and PLCs behave in production networks, not just theoretical vulnerability databases. Skip this if you need real-time continuous monitoring or remediation workflows; Redpoint is an enumeration tool for the discovery phase, not an operational platform.
