Trust Score analytics
How ZeroTrace Proxy sums up a proxy's quality into a single letter grade — the four factors, the three weighting profiles, and the bands they map to.
Every proxy you check produces a lot of separate facts — is it alive, how fast, how anonymous, does it carry HTTPS, does it leak. Trust Score rolls those facts into one 0–100 score, a letter grade, and a band, so you can sort a big list at a glance and reach for your best proxies first without reading every column. It is computed locally from the check result each time you view it — nothing is sent anywhere to score a proxy.
The four factors
Every alive proxy is scored on four factors, each normalized to 0–100:
| Factor | What it measures | How it's scored |
|---|---|---|
| Anonymity | How well the proxy hides that you're using it, and your real address | Elite 100 · Anonymous 70 · Unknown 45 · Transparent 25 |
| Speed | Latency from the check | under 300ms → 100 · under 800ms → 80 · under 1500ms → 55 · under 3000ms → 30 · 3000ms or more → 10 · no reading → 50 (neutral, not penalized) |
| HTTPS support | Whether the proxy can carry secure traffic | Supports HTTPS → 100 · does not → 60 |
| Quality | The proxy's underlying quality score from Check (protocol behavior, auth, latency banding) | Carried through directly · missing → 50 (neutral, not zero) |
Weighting it to your work: the three profiles
Not every job values the same things. Trust Score gives you three profiles that re-weight the same four factors — switch profiles and the same checked proxies re-grade against what you value, with no need to re-check anything.
A sensible default that leans slightly toward anonymity and speed over the other two.
| Factor | Weight |
|---|---|
| Anonymity | 30% |
| Speed | 30% |
| HTTPS | 20% |
| Quality | 20% |
For when staying hidden matters most — anonymity dominates the grade, speed barely counts.
| Factor | Weight |
|---|---|
| Anonymity | 50% |
| Speed | 10% |
| HTTPS | 20% |
| Quality | 20% |
For when throughput matters most — latency dominates, anonymity and HTTPS count for little.
| Factor | Weight |
|---|---|
| Anonymity | 15% |
| Speed | 55% |
| HTTPS | 10% |
| Quality | 20% |
The score is the weighted sum of the four factors under the active profile, rounded to a whole number.
Grade and band
The numeric score maps to both a letter grade (for a quick label) and a band (for filtering and color):
| Score | Grade | Band |
|---|---|---|
| 90–100 | A+ | Ready (≥80) |
| 85–89 | A | Ready |
| 75–84 | B | Ready / Good |
| 60–74 | C | Good |
| 40–59 | D | Review (≥35) / Avoid |
| 0–39 | F | Avoid |
Bands: Ready (≥80) — use it with confidence. Good (≥60) — solid, worth using. Review (≥35) — usable but check it fits the job. Avoid (below 35, or dead) — drop it.
