Layer3 Intel monitors more than 200 proxy providers and continuously maps residential, mobile, and ISP proxy infrastructure as it changes in real time.

Residential proxies

Live visibility into residential exit nodes used by rotating proxy networks.

Mobile proxies

Detection for proxy traffic exiting through mobile carrier networks (LTE/5G)

ISP proxies

Static residential allocations, hosted ISP blocks, and hybrid proxy infrastructure.

// threat detection for the modern era

Anonymized infrastructure detection

Modern threat actors circumvent legacy detection mechanisms with ease by using real residential IPs, bypassing traditional IP reputation and WAF defenses.

01

Capture

The Tripwire SDK performs real time connection assessments and returns a stateless encrypted token that you can decrypt server side to verify client integrity.

l4 rtt: 74ms
l7 rtt: 314ms
ttl: 117
ja4: "t13d1516h2…"
02

Fingerprint

We reconstruct the originating OS and network stack from those signals - and compare it to what the client claims. Proxies relay traffic; they can't change the host's TCP/IP DNA.

Score

Every IP carries a live threat score built from observed proxy activity - the pools it's active in, how often we see it, and when it was last observed. Block, challenge, or allow - your rules, our intel.
