05Intelligence
IP reputation seen by many servers, without exposing any of them.
When several organizations see the same IP attacking, it earns a reputation. Yours only takes part if the account owner agrees, and can leave whenever they want.

02Rules
Rules designed so nothing leaks sideways.
- Owner opt-in
- Off by default. Acceptance records the text version, who accepted and when.
- Threshold of 3
- A lookup only shows network data when at least three other organizations contributed. Sources appear in ranges (3 to 9, 10 or more) and dates only by day.
- Revoking
- Leaving deletes, in the same transaction, your organization's signals and aggregated contributions.
- Granularity
- IPv4 is evaluated per /32 and IPv6 per /64. Signals are kept for 90 days.
- False positive
- An IP marked as a false positive or allowed stops counting your contribution.
- Lookups
- 50 reputation lookups per day on Dev and 500 on Pro.
03Sensors
Platform honeypots on three continents.
Sincro8 runs sensors in Europe, the United States and Brazil. They feed the network, but on their own they never give High confidence: an independent organization must have seen the same IP.

Preventive blocking based on reputation doesn't exist yet. When it comes, it will be a separate opt-in, after weeks of observation.
