Security and trust
Privacy is the product, not a policy.
Every sharing decision runs through one server-side authorization layer and one reporting threshold, on every read, on every surface. This page shows the mechanism working.
Try it yourself.
Flip Larkfield Dynamics's sharing level and watch what they would see change. It runs Co-Signal's own redaction rules on sample data, in your browser, with no network call.

What Larkfield Dynamics sees
Counts only
Fewer than 5
Suppressed, below the k-anonymity reporting threshold.
Under 5
Counts below 5 are never shown as a number, so no single account can be inferred.
Counts first
Every new partnership starts at counts only. Nothing is visible until you open it up.
One layer
The web app, Slack, the agent, the MCP server and CRM writeback all ask the same layer.
Every change
Loosening or tightening a partner's access, or the fields you share, is written to an audit log.
Sample data. Every name is fictional.
One authorization layer. Every surface.
The web app, Slack, the AI agent, the MCP server and CRM writeback all ask the same layer what a partner may see. Every sharing change is written to an audit log, shaped like the specimen below.

Every sharing rule is checked on the server, on every read.
What we actually do.
01
Encrypted CRM tokens
Every connected Salesforce or HubSpot token is encrypted at rest and never stored in plain text.
02
Server-side enforcement, every time
The same layer decides what a partner sees, whichever surface is asking.
03
An audit log of sharing changes
Every time a company loosens or tightens a partner's access, or changes the fields it shares, the change is logged.
04
Conservative defaults
Every new partnership starts at counts only. Nothing is visible to a partner until you open it up.
