What is a residential proxy?

A residential proxy routes traffic through an actual residential internet connection, making the traffic appear as though it originates from a standard home user rather than a datacenter. These are heavily used by sophisticated scrapers and credential stuffing attacks.

Can I block all proxies?

While possible, blocking all proxies may result in high false positives (e.g., blocking corporate proxies). We recommend introducing adaptive friction, such as requiring MFA or a CAPTCHA, instead of outright blocking.

How accurate is the VPN detection?

Our system combines real-time node databases, threat intelligence feeds, and ASN classification to accurately identify nodes belonging to commercial VPN networks like NordVPN, ExpressVPN, and others.

Does this API detect datacenter IPs?

Yes, the API returns an ASN classification field that explicitly flags IPs originating from hosting providers, datacenters, and cloud platforms like AWS or GCP.

Will proxy blocking hurt my SEO?

No. Our network API simultaneously checks if the IP belongs to a verified search engine bot. Legitimate crawlers like Googlebot are explicitly flagged, allowing you to bypass proxy rules for good bots.

How often do you update the proxy lists?

Our systems continuously aggregate data from global honeypots, public proxy lists, and threat intelligence feeds. Edge nodes receive updates asynchronously in near real-time.

Proxy & VPN Detection

Stop fraudsters hiding behind anonymizing networks. The endpoint analyzes the incoming IP against a constantly updated database of known open proxies, SOCKS nodes, and HTTP proxies to reveal the true nature of the traffic.

Real-time Database
Instantly checks against live databases of known proxy IPs.
Open Proxy Detection
Catch insecure and public proxies often used for low-sophistication attacks.
SOCKS & HTTP
Broad coverage across multiple proxy protocols and port configurations.

Residential Proxy Intelligence

Attackers increasingly use compromised IoT devices and residential broadband connections to mask their attacks. Our intelligence layer identifies traffic acting as residential gateways for botnets and scrapers.

Residential Flagging
Catch sophisticated botnets operating through standard ISP connections.
Abuse History
Correlate IPs with known spam and hacking blacklist databases.
Adaptive Friction
Force MFA or CAPTCHA challenges when residential proxy traffic is detected.

Datacenter & Commercial VPN Flagging

Legitimate users rarely browse from AWS or DigitalOcean. Detect connections originating from cloud providers and accurately flag traffic from popular consumer VPN networks like NordVPN, ExpressVPN, and Surfshark.

Hosting Classification
Identify traffic originating from datacenters and server farms.
Commercial VPN Flags
Accurately detect traffic from popular consumer VPN providers.
Rule Flexibility
Choose to block datacenters while allowing consumer VPNs based on your risk profile.
