VoIP threat intelligence
VoIP threat intelligence built for SIP, not repurposed from email feeds.
SipRadar is a VoIP-native threat intelligence platform. We collect SIP-specific signals from a global honeypot mesh, grade attacker infrastructure, and deliver actionable feeds for sysadmins, MSPs, and SOC teams.
General threat intel fails VoIP teams
Email and web reputation feeds were not designed for SIP. They miss REGISTER floods, premium-rate INVITE routing, and scanner user-agents like friendly-scanner and VaxSIPUserAgent. VoIP ops teams need intelligence that understands ports 5060–5062 and PBX attack patterns.
A threat graph trained on SIP behavior
Every event in SipRadar comes from a honeypot that speaks SIP. We correlate IPs, ASNs, user-agents, and attack cadence into a 0–100 threat score. The same graph powers our dashboard, API, and blacklist feeds.
How SipRadar helps
Global honeypot mesh
214 sensors across 38 countries capture live SIP scans, brute-force attempts, and toll-fraud probes 24/7.
Unified API surface
One API for IP lookup, live threats, blacklist export, and remote PBX audits. SDKs for PHP, Python, and Node.js.
SOC-ready exports
Stream JSON to your SIEM, export CSV from the dashboard, or pull plain-text blacklist.txt for edge firewalls.
EU-hosted, GDPR-aligned
Primary processing in Frankfurt with Amsterdam standby. Enterprise customers receive a standard DPA.
Wire into your security stack
Connect SipRadar to Fail2Ban, Kamailio, Asterisk ACLs, or your existing SOAR playbooks. See our API documentation for authentication, rate limits, and webhook payloads.
FAQ
Frequently asked questions
Common questions about VoIP threat intelligence and how SipRadar fits your VoIP security stack.
Ask a question →IP reputation scores generic abuse across protocols. VoIP threat intelligence focuses exclusively on SIP attack patterns (registration floods, toll fraud INVITEs, and scanner fingerprints), producing far fewer false positives for telephony operators.
