SignalWire Trust Center
Voice, messaging, video, fax, and AI services run with consistent controls: encryption everywhere,
role-based access + 2FA, scoped credentials, and audit trails across the communications stack.
We make sure every interaction is secure, private, and reliable so you can focus on what you're building — not what might break.
We design every layer of our infrastructure with security in mind. That means strict controls, constant monitoring, and encrypted pathways — everywhere.
Learn MoreSignalWire supports SOC 2 Type II, HIPAA, and GDPR, with built-in access controls, audit logging, and data retention designed to meet regulatory standards across industries.
Learn MoreSignalWire’s architecture includes multiple layers of redundancy and intelligent failover. We ensure your services stay connected — even under load, during outages, or across regions — because reliability isn’t optional.
Learn MoreYou always know how your data is handled, where it resides, and who can access it. Our global data center network supports data residency and sovereignty requirements with region-specific routing.
Learn MoreSignalWire delivers modular, programmable unified communications with zero trust assumptions, isolated services, scoped credentials, and proactive security measures across the stack.
All communication and data are encrypted by default using protocols that exceed industry standards, regardless of the channel or device.
TLS 1.2/1.3 for encrypted signaling across HTTP, SIP, and websockets
SRTP + DTLS for voice and video
AES-256 and RSA-4096 encryption for storage
Secure transmission across HTTPS and encrypted websocket channels
We continuously monitor, test, and improve our platform to detect vulnerabilities early and respond before they become threats.
Static and dynamic code analysis in the CI/CD pipeline
Real-time intrusion detection with automated alerting
Continuous vulnerability scanning and behavior analytics
Third-party penetration tests and independent security audits
Our infrastructure is built to limit exposure by default. We separate workloads, restrict access, and enforce strong authentication across all systems.
Isolated environments for voice, video, messaging, fax and AI services
Scoped credentials for every application and integration
Role-based access control with two-factor authentication (2FA)
Fine-grained permission management for internal and external tools
SignalWire’s infrastructure is designed for secure, high-performance communication services. We regularly undergo penetration testing, vulnerability assessments, and 24/7 monitoring to ensure data integrity and protection. All communications are encrypted in transit and at rest using industry-standard protocols.
Datasphere’s API interactions are protected by role-based access control, and all data retrievals are logged and monitored in real-time. Vectorized data is encrypted, and integration with SWAIG ensures a secure environment for AI interactions.
SignalWire adopts a DevSecOps approach where security is built into every phase of development. Static and dynamic application security testing (SAST/DAST) is regularly conducted, and our SWML resources are designed to minimize common risks, like code injection.
SignalWire follows a structured incident response process. If a breach or vulnerability is detected, a dedicated team initiates containment, investigation, and remediation activities. Customers are promptly notified if they are impacted.
SignalWire’s infrastructure is designed with redundancy and failover mechanisms to ensure high availability. Our uptime SLA guarantees a minimum of 99.99% availability. With globally distributed infrastructure, real-time monitoring, and automated failover, we minimize disruptions.

Protecting your SignalWire account is essential for ensuring the security of your communications and compliance with organizational standards. Follow these best practices to secure your account and sensitive data:
SignalWire provides robust options to securely manage sensitive data, such as API keys, access tokens, and passwords, within your workflows. By following best practices for secure storage and sharing, you can protect critical information and minimize risks.
SignalWire enables you to define custom roles for team members to control access to projects within your SignalWire Space. By tailoring roles to the needs of each user, you can enhance security and limit exposure to sensitive information.
Leverage SignalWire’s audit logs to monitor your account for unusual activity, such as unexpected changes to settings or unauthorized access attempts. Regularly reviewing audit logs helps ensure that only authorized users are accessing your projects and resources. Additionally, SignalWire audit logs can be integrated with your organization’s security information and event management (SIEM) tools via APIs, providing a comprehensive view of account activity and strengthening your security posture.
Establish a peer review process for critical projects and configurations. Regularly review and approve updates to workflows or scripts, use version control tools to track changes, and incorporating testing steps will help to prevent unintended security risks.
