A transparent 0–100 signal. Every entity starts at a neutral baseline of 65; threat-intel blocklists, exposure, reverse-DNS, routing and allocation each adjust it up or down. Higher is more trustworthy.
- Baseline (neutral) 65
- Has a reverse-DNS (PTR) record +5
- Enterprise allocation +4
- Established allocation (12y) +3
- Trust score 77 / 100
