sixnet-tools vs Cydome GPS/GNSS Spoofing Monitoring: 2026 Comparison

Critical infrastructure security teams defending legacy Sixnet RTUs in SCADA environments should use sixnet-tools to validate whether their deployed units are exploitable without requiring expensive vendor engagement or network downtime. The tool demonstrates real application-level vulnerability chains against Sixnet hardware that vendors often leave unpatched in production environments, making it invaluable for gap assessment. Skip this if your RTUs are air-gapped or running behind properly segmented industrial control networks; the 16 GitHub stars and free distribution suggest limited ongoing maintenance, so treat it as a one-time assessment tool rather than continuous monitoring infrastructure.
