Market Segmentation Overview
By Deployment Mode
| Sub-Segment | Key Trend |
| On-Premise | Retained for classified, central-bank and national health workloads under multi-year accreditation cycles |
| Cloud | Consumption-priced hosting displacing owned server estates; carrier edge sites emerging as a second supply channel |
Cloud holds 61.5% of 2025 revenue and grows fastest at 9.1% annually, because concurrency-based buying matches how shift-driven workforces consume sessions and removes the capital approval step that stalls On-Premise expansion. On-Premise does not disappear; defence and central-bank buyers specify physical custody as a procurement condition, and their accreditation cycles run five to seven years, which locks in a durable installed base. Large accounts increasingly split the estate, running regulated workloads on-premise while general workforce sessions move to hosted capacity.
By End-user Vertical
| Sub-Segment | Key Trend |
| BFSI | Communications surveillance and trade-capture obligations keep session data inside supervised infrastructure |
| Healthcare | Shared clinical handsets cleared between shifts without touching clinician personal content |
| Government and Defense | Zero-trust deadlines drive device-issuance avoidance across cleared and civilian agencies |
| Telecommunications and IT | Outsourced contact-centre seats converted to hosted sessions for rapid scaling |
| Manufacturing | Contract and seasonal workforce onboarding without hardware provisioning |
| Other End-User Verticals | Retail, logistics and education deployments driven by turnover economics |
BFSI leads at 24.6% share because banking supervisors examine the communication channel itself, and hosted delivery keeps chat and trade records inside auditable infrastructure rather than on a trader's handset. Healthcare grows fastest at 9.4% as hospitals standardise on shared devices that must be wiped between shifts under clinical safety documentation requirements. Government and Defense contributes the largest absolute public-sector spend, while Manufacturing and Other End-User Verticals expand in step with seasonal hiring rather than regulation, giving them a more cyclical demand profile than the regulated verticals above them.
