Switch & PBX security
Lock down your switch before attackers find it.
Softswitches, hosted PBXs and SIP trunks are prime targets for toll fraud. VoIP Radar watches registrations, invites and routes continuously and cuts off attackers before a single fraudulent minute is billed.
Threats we stop
What VoIP Radar protects you from
An unattended weekend of toll fraud can cost more than years of protection. These are the attacks we shut down at the edge.
Registration brute force
Password-guessing against extensions and SIP accounts is fingerprinted and blocked on the first burst, before a rogue device can register.
International toll fraud
Unusual calling to premium and high-risk international destinations is scored per call and dropped, limiting exposure to zero completed minutes.
Compromised extensions
Off-hours dialing, sudden volume and never-before-seen destination countries flag accounts behaving unlike their owners.
Rogue trunks & routes
New or modified routes are compared against historical patterns so misconfigurations can't quietly become a fraud channel.
Fraudulent sign-ups
KYC checks and red-flag detection stop bad actors at onboarding — before they get a trunk, numbers or credit.
Robocall origination abuse
Auto-dialer bursts from a single customer are detected and throttled, keeping your network off carrier and regulator radar.
Integration
Works with the infrastructure you already run
VoIP Radar deploys next to your existing platforms — no rip-and-replace. It is commonly used with FreeSWITCH, Asterisk, Kamailio, OpenSIPS, Metaswitch, Ribbon, Sansay, Oracle/Acme Packet SBCs and cloud UCaaS stacks.
Integration is typically a routing change: your switch asks VoIP Radar for a decision (SIP redirect or API) and acts on the answer. Signaling-only inspection means media never leaves your network.
Hardening checklist we help you enforce
- Per-account international and premium-rate dialing limits
- Velocity limits on concurrent calls and calls per second
- Geo and IP allow-lists for SIP registrations
- Automatic suspension when spend or minutes exceed a baseline
- Out-of-hours calling policies per tenant
- Real-time alerts to email, Slack, Teams or webhook
