What Happened — ZDNet published a hands‑on evaluation of eight leading cloud‑based phone system providers, ranking them by overall fit, AI capabilities, SMB suitability, and other criteria. The article includes pricing insights, feature comparisons, and user‑experience notes to help enterprises select a vendor.
Why It Matters for TPRM —
- Cloud telephony platforms handle voice, video, and data traffic, making them a critical communication backbone for many third‑party relationships.
- Vendor selection influences exposure to supply‑chain risks such as data leakage, insecure APIs, and service outages.
- The review highlights AI‑driven features that may introduce new privacy or compliance considerations (e.g., call transcription, sentiment analysis).
Who Is Affected — Enterprises across all sectors that rely on hosted voice services, especially those in TELCO, TECH_SAAS, and PROF_SERV (call centers, support teams).
Recommended Actions —
- Incorporate the ranked vendors into your vendor‑risk inventory and assess each against your organization’s security controls.
- Verify that providers demonstrate robust encryption, data residency, and audit‑log capabilities for call recordings and AI analytics.
- Conduct a comparative risk assessment focusing on business continuity, incident‑response SLAs, and third‑party certifications (e.g., ISO 27001, SOC 2).
