ISO 27001-Aligned Security Practices for Voice, SMS, and IVR

What Is ISO 27001?

ISO/IEC 27001 is an international standard for information security management systems (ISMS). It provides a framework of policies, procedures, and controls designed to manage and protect sensitive data, reduce risks, and improve the overall security posture of an organization.

While ISO 27001 certification is not legally required for most organizations, aligning with its principles helps demonstrate a commitment to data security, privacy, and risk management, especially for businesses in regulated industries like healthcare, finance, and government.
