The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Blackfire, not the verdict.

|---|---|---|---|---|
| Security Posture | 85 | 22.00 | 1870.0 | ✓ |
| Reliability | 50 | 30.00 | 1500.0 | ✓ |
