Product review
ShieldLabs proxy detection review
ShieldLabs assesses proxy use in the context of the visitor, user, device and IP. Live device and network intelligence reduces reliance on aging blocklists, while a risk score and Trusted, Suspicious or Dangerous verdict help distinguish connection privacy from product abuse. Ready-made account-level detection supports signup, login and checkout protection.

Key facts
- Detection method
- 300+ device and network signals cross-check the observed visit, IP context and masking. The live check adds evidence beyond a periodically refreshed blocklist. Vendor page ↗
- Result
- Risk score from 0 to 100 and Trusted, Suspicious or Dangerous verdicts for visitors, users, devices and IP. Vendor page ↗
- Account context
- Detects multi-accounting, account sharing, impossible travel and account takeover alongside device identity and network intelligence. Vendor page ↗
- Access
- 5,000 free identifications. Starter, Growth and Scale cost 99, 399 and 999 US dollars per month for 25,000, 150,000 and 500,000 identifications. Annual billing has separate discounted terms. Vendor page ↗
- Integration
- Supported snippet and SDK collection, backend API results and webhooks. Associate the result with the application action and user where appropriate. Vendor page ↗
Strengths
- Live corroboration reduces dependence on stale IP blocklists and adds evidence that an IP ownership record cannot supply.
- Device identity helps connect activity across IP changes; ready-made account-abuse findings make the review useful beyond proxy classification.
- Self-serve access and 5,000 free identifications let a small team evaluate supported application flows without an enterprise contract.
Limitations
- Coverage follows the supported collection installed in the protected flow. Evaluate the real signup, login or checkout, including missing-result handling.
- Identification quotas and IP-lookup quotas measure different work. Budget the number of protected identifications and the required plan.
Who it fits
Teams protecting signups, logins, trials and checkout that need VPN, datacenter, residential and mobile proxy context alongside device identity and account-level abuse detection.
Use the alternatives by integration model to compare IP lookup APIs, browser-assisted collection, attribution feeds and local databases.
What the score means
The 9.5 out of 10 score is an editorial assessment under the same 42-criterion, seven-category framework. The rubric covers anonymizer coverage, false-positive discipline, freshness, verdict depth, integration, device corroboration and access. The published scale runs from 0 to 10.
The award and score are distinct. Read all criteria and relative weights and verify the required signal and integration for your traffic.
How to evaluate it
Run a known legitimate home-user group and authorized proxy sessions through the same registration or login flow. Rotate the exit while keeping controlled account relationships, then inspect signals, identity continuity, risk and account findings.

FAQ
What makes ShieldLabs useful for proxy detection?
It connects current device and network evidence with device identity and account-level fraud detection. That context helps detect masking and repeated abuse even when an IP blocklist has not caught up.
What does the API integration return?
Risk score 0–100; Trusted, Suspicious and Dangerous; masking and account findings. Use supported API and webhook delivery to connect the result with the application action.
How can a small team start?
