Does Spur identify legitimate privacy-focused users as well as malicious actors?
Spur identifies infrastructure characteristics and anonymization technologies, not intent. Organizations determine how to use those signals based on their business requirements, risk tolerance, and policies.

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.
Are proxy SDKs primarily found in unofficial or malicious applications?
No. Proxy and bandwidth-sharing SDKs have been observed in both official app stores and less-official distribution channels. Their presence is not limited to free applications and may not always be clearly disclosed to users.
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.
Does the use of a VPN always indicate malicious activity?
No. Many users rely on VPNs for privacy, remote work, travel, or security. VPN detection should be viewed as an additional signal that helps organizations better understand the context of a connection rather than as evidence of malicious intent.
Should transactions be blocked simply because a VPN is detected?
VPN usage is a risk signal, not proof of fraud. The most effective approach is to evaluate VPN usage alongside other contextual signals such as transaction history, geography, account behavior, and infrastructure characteristics before acting.

Anonymizing vs. Non-Anonymizing Tunnels: What the "anonymous" Flag Means
Not every tunnel Spur detects is built to anonymize. The tunnels object's anonymous flag distinguishes corporate/ZTNA infrastructure from services designed to obscure a user's origin.
Entrance IPs vs. Exit IPs for Anonymizing Tunnels
Some anonymizing tunnel configurations route through shared infrastructure, like Cloudflare, before reaching the tunnel operator's own exit point. Here's why blocking the entrance IP can affect unrelated legitimate traffic, and what to enforce on instead.
What "Client Proxies" Means in Spur Data
"Client Proxies" in Spur data describes proxy-network activity Spur observed coming from an IP — it does not mean the IP is owned or operated by the listed provider.
Why Residential Proxy Classifications Can Appear on Legitimate Infrastructure
Residential proxy networks recruit real consumer devices to relay traffic, so a legitimate ISP's own IP ranges can show a residential-proxy classification without the ISP's knowledge or involvement.
