Product review
ShieldLabs proxy detection review
ShieldLabs combines live proxy and VPN detection with device identity, IP intelligence and account-level fraud detection. It checks device and network evidence at the time of the visit, helping catch masked traffic that an aging IP blocklist misses, then connects it to visitor, user, device and account risk.

Key facts
- Method
- Cross-checks 300+ device and network signals. Network Intelligence examines IP context, connection masking and device/network mismatches alongside the observed visit. Vendor page ↗
- Proxy scope
- Detects proxy and VPN masking, including residential and mobile exit context when available. Live device/network checks add evidence beyond a known-IP list. Vendor page ↗
- Result
- Risk score from 0 to 100, with Trusted, Suspicious and Dangerous verdicts for visitors, users, devices and IP, plus inspectable signals and linked identities. Vendor page ↗
- Account-level abuse
- Ready-made Multi-accounting, Account sharing, Impossible travel and Account takeover detection. Event confidence is Medium or High, separate from the risk score. Vendor page ↗
- Access
- 5,000 free identifications. Paid monthly plans are 99 / 399 / 999 US dollars; Starter includes 25,000 identifications. Annual billing starts at an effective 79 US dollars per month. Vendor page ↗
- Integration
- Supported client/server SDKs, API results and webhooks. Install collection in the protected flow and associate the application 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
- Live observations require the supported integration in the relevant flow; an old IP list cannot recreate a past browser session.
- An IP-only batch lookup and a live visitor identification have different integration requirements; use the protected flow to evaluate device and account findings.
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 evidence layer to compare IP feeds, live session checks and managed traffic protection.
What the score means
The 9.6 out of 10 score is an editorial assessment under the same 39-criterion, seven-category framework. The rubric emphasizes proxy coverage, false-positive control and corroboration beyond IP ownership. 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
How does ShieldLabs detect proxy and VPN abuse?
It combines current device/network intelligence, IP context and connection-masking detections with device identity, a risk score and ready-made account-level abuse findings. This reduces dependence on periodically updated IP blocklists.
Why choose it over an IP database alone?
It adds observed device identity, risk verdicts and ready-made account-abuse findings to IP and network context. An observed-exit IP feed can complement those live checks.
What can I test for free?
Use the live demo for a permitted visit and the 5,000 free identifications for the supported integration. Starter costs 99 US dollars per month for 25,000 identifications.
