Purpose-Built Security

Role-Based Access Control (RBAC) is baked in, so you can assign precise permissions to users and services without your own auth layer. And with scoped API keys, you can limit access by function and surface area.

Built-in anti-DDoS protections guard against signaling floods, malformed requests, and brute-force attempts without extra configs or third-party services. Because every resource runs in a tightly scoped container, there’s no risk of multi-tenant bleed or cross-project leaks.

Global, Reliable & Fast

Geo-distributed architecture ensures your app is always close to your users, with media and routing optimized to deliver under 50ms latency.

With POPs positioned close to end users, and infrastructure deployed across trusted providers, your communications stay fast, available and resilient.

No Walled Gardens, No Black Boxes

SignalWire gives you real-time access to the core—not only endpoints. With open APIs, SDKs, and a resource model built around SIP, HTTP, and programmable logic, you can build, integrate, and customize every layer of your communications stack.

• Connect directly to your stack with RESTful APIs.

• Spin up AI Agents, IVRs, and call flows—all from code.

• Deploy your own carrier or use ours.
