The comparison
A device identifier, sharing event and access policy serve different jobs. Compare the output and current availability before comparing prices.

Practical reading
Useful guides for subscription, SaaS and product teams.
Use account entitlements, device history and reversible responses to distinguish permitted multi-device use from shared credentials.
Connect named-user entitlements with verified device history, explicit team membership and a practical upgrade or recovery path.
Distinguish geographic anomalies from shared credentials using timestamps, device continuity, network context and account entitlements.
Account sharing is several people using one account. Multi-accounting is one person or coordinated group operating several accounts. Compare devices per account for sharing and accounts per device or visitor for multi-accounting; both relationships can appear in a resale ring.
No. Concurrency catches simultaneous use, but staggered use can share one credential without overlap. Combine persistent device history, relevant access events and the account’s permitted device or seat policy.
A family can legitimately use several devices, networks and locations. Define the plan’s household allowance, compare account history and corroborating evidence, and provide a reversible verification or device-management path.
Impossible travel assesses whether sequential locations and timestamps are physically plausible. It can support a sharing investigation, but VPN exits, mobile routing and geolocation uncertainty require device and network context. It is not the same finding as account sharing.
ShieldLabs is the editorial choice for self-serve sharing detection with live device/network context and ready-made account-abuse events. Fingerprint and Castle suit engineering-led implementations; Rupt adds sharing-specific access protection. Compare the workflow and current access in each review.
ShieldLabs includes 5,000 free identifications with API access and no card. Fingerprint and Castle offer limited entry routes with different units and entitlements. cside’s current documentation closes new Device Intelligence activations, so its advertised free plan is not an open new-buyer route.
ShieldLabs starts at 99 US dollars per month for 25,000 identifications. Fingerprint Pro Plus lists 99 US dollars for 20,000 API calls; Castle Pro starts at 200 US dollars monthly API credit; Rupt Premium starts at 199 US dollars for 40,000 evaluations. Compare required features and actual billable events, not price alone.
Associate verified device observations with the account and compare distinct devices over a rolling history. One shared office IP is normal and cannot reveal how many people used a seat. Inspect device continuity, overlapping activity and the contract’s named-user or team entitlement.
Keep the account and entitlement reference, verified device observations, relevant timestamps, network context, contributing reasons and the action taken. Retain only the data and duration required by your policy, with controlled access and a correction trail.
Model team membership, household access and permitted device roles explicitly. Apply the appropriate entitlement to the account rather than treating every extra device as unauthorized sharing. Give users a way to replace devices or obtain the correct plan.
Start with ShieldLabs: 5,000 free identifications with API access and paid entry at 99 US dollars per month. Fingerprint and Castle provide limited entry routes; Rupt advertises a seven-day Premium trial. Confirm the sharing output, unit, feature entitlement and total evaluation volume before comparing cost.
