Are proxy SDKs primarily found in unofficial or malicious applications?

What is the difference between a VPN, residential proxy, and ISP proxy?

Residential proxies route traffic through consumer devices and physical locations like homes and offices, while VPNs and ISP proxies are typically hosted in data centers. All three can present different network profiles.

What should I do when I detect a VPN or proxy?

Detection alone should not automatically trigger a block. VPNs and proxies are used by both legitimate users and attackers. Most organizations incorporate VPN and proxy signals into broader risk-scoring or adaptive decisioning workflows that consider account history, geography, transaction context, and behavioral indicators.

What should an ISP, hoster, or ASN owner do if they discover residential proxy activity within their address space?

Organizations should investigate affected customers or devices, review acceptable-use policies, validate indicators, notify impacted parties when appropriate, and coordinate remediation efforts. Infrastructure owners are often in the best position to disrupt abuse occurring within their networks.

What indicators may suggest a candidate or worker is masking their location?

Potential indicators include repeated VPN usage, residential proxy activity, frequent geographic inconsistencies, remote-access tooling, rapid location changes, and infrastructure patterns inconsistent with the worker's claimed location.

Why isn't traditional IP geolocation enough to enforce geographic restrictions?

Traditional geolocation only identifies where an IP address appears to be located. It does not reveal whether traffic is being routed through a VPN, residential proxy, mobile proxy, or other anonymization service. As a result, users can appear to originate from approved locations while actually operating elsewhere.
