SignalWire is officially ISO 27001 certified, reinforcing our commitment to protecting customer data across programmable voice, messaging, video, and AI-powered communications.
ISO 27001 certification confirms that SignalWire operates a formal, audited Information Security Management System (ISMS) aligned with internationally recognized best practices for identifying, managing, and reducing information security risk across our people, processes, and technology.
For organizations building on SignalWire, this certification provides independent validation of ISO 27001 compliance as a company-wide, continuously managed system.
What is ISO 27001?
ISO 27001 is the global standard for information security management systems, published by the International Organization for Standardization and the International Electrotechnical Commission.
The standard defines how organizations should systematically:
Identify and assess information security risks
Implement risk-based security controls
Establish governance, policies, and accountability
Continuously monitor, audit, and improve security practices
SignalWire is now certified to ISO 27001:2022, the most recent version of the standard, which strengthens guidance around modern threat models, operational resilience, and continuous improvement.
Why ISO 27001 matters for modern communications platforms
Communications platforms sit directly in the path of all kinds of sensitive data: voice conversations, text messages, call metadata, authentication flows, and application logic. Security failures at the infrastructure layer can cascade quickly into customer risk.
Passing an independent ISO 27001 audit matters because it demonstrates that a communications provider:
Uses a risk-based approach, not ad-hoc security controls
Applies security consistently across teams, systems, and vendors
Maintains clear processes for incident response and escalation
Treats security as an ongoing operational responsibility
What ISO 27001 certification means at SignalWire
ISO 27001 certification validates that SignalWire has implemented and operates a company-wide ISMS covering how we design, build, operate, and support our platform to identify, manage, and mitigate information security risks.
In practice, this includes:
Risk-based security management
SignalWire performs structured risk assessments to identify potential threats, evaluate impact, and apply appropriate controls. Security decisions are guided by risk.
Documented policies and governance
We maintain formal security policies, defined ownership, and internal controls that govern how information is handled across engineering, operations, and business functions.
Incident management and response
Clear processes are in place for detecting, responding to, and learning from security incidents, ensuring accountability and continuous improvement.
Continuous monitoring
ISO 27001 requires ongoing review, audits, and updates. Certification is not a one-time event. It’s a system that evolves alongside our platform and the threat landscape.
Security as part of company culture
Security training, awareness, and responsibility extend beyond the security team. ISO 27001 embeds security into day-to-day operations across SignalWire.
ISO 27001 and SignalWire’s Programmable Unified Communications (PUC) Platform
SignalWire’s PUC platform is designed for developers building real-time, programmable communications across voice, messaging, video, fax, AI, and more.
ISO 27001 certification complements our architecture by ensuring that:
Platform security is managed systematically, not reactively
Operational controls support reliability, integrity, and availability
Customers can build applications on a security-first foundation that supports compliance requirements
For teams deploying communications in regulated or high-trust environments, ISO 27001 certification provides an additional layer of assurance.
