Softswitches, PBXs, and SIP trunks are the #1 target for toll fraud. SipShield's patented AI watches every registration, invite, and route in real time — shutting down attackers before a single fraudulent minute completes.
One weekend of unattended toll fraud can cost more than an entire year of protection. Here's what we shut down before it starts.
Automated password-guessing against extensions is fingerprinted and blocked at the first burst — before an attacker can register a rogue endpoint.
Suspicious dialing to premium-rate and high-risk destinations is scored in real time and dropped, capping exposure at zero completed calls instead of thousands of dollars.
Anomalous behavior — off-hours calling, sudden volume, new destination countries — flags extensions that legitimate users would never trigger.
New routes and trunks are risk-scored against historical patterns so scammers can't quietly slip traffic through a misconfigured softswitch.
Automated KYC pairs identity verification with red-flag detection (virtual offices, mismatched addresses, crypto payments) so bad customers never provision service.
Auto-dialer bursts from a single customer are identified and rate-limited, keeping your ASN off carrier and FCC blocklists.
SipShield deploys alongside the softswitch and SBC platforms you already run — no rip-and-replace. Whether you're on FreeSWITCH, Asterisk, Kamailio, OpenSIPS, Metaswitch, Ribbon, Sansay, or a cloud UCaaS stack, SipShield inspects signaling and metadata in-line without adding latency to legitimate calls.
