Kamailio security
Kamailio security for carriers and SBC operators.
Kamailio sits on the front line of SIP traffic. SipRadar gives your edge real-time attacker intelligence to feed dispatcher, permissions, or external blocklists from honeypot-verified sources.
SBCs see the first wave of attacks
Before traffic reaches Asterisk or FreeSWITCH, Kamailio absorbs REGISTER floods and INVITE scans. Without VoIP-specific threat intel, you rely on rate limits alone, which attackers bypass with distributed sources.
Threat-aware edge policies
Import SipRadar blacklist feeds into Kamailio routing logic. Combine with pike, iptables, or nftables for layered defense. Our API returns geo, ASN, and user-agent context for custom routing decisions.
How SipRadar helps
Dispatcher-friendly feeds
Load high-threat IPs into dispatcher sets or external block scripts updated via cron or API polling.
Real-time JSON stream
WebSocket and REST options on paid tiers for sub-minute blocklist refresh at scale.
Carrier-grade API limits
Enterprise plans include unlimited requests and private honeypot deployments for regulated environments.
Remote Kamailio audit
Verify TLS, open listeners, and authentication posture on your public SIP interface.
API + Kamailio scripting
Use httprequest or external tools to pull /v1/threats, then apply blocks in request_route. See API docs for authentication and filtering parameters.
