Detecting sharing means telling a genuine multi-device household or team apart from credentials passed around, or, increasingly, a session token handed to an AI agent acting on the user's behalf. cside reads 250+ per-session signals to fingerprint each device on an account cookielessly, then flags when the number and pattern of devices looks like sharing rather than a household. Because it also classifies whether a session is a human, a bot, or an agentic AI client, it catches the newer case where a credential or token is shared with an AI agent, without adding login friction for real users.
