While both systems have their appeals, a cloud PBX solution offers more security benefits than an on-prem which are limited to what they can offer. But, an on-prem can be safe as long as best security practices are applied and maintained.  Hosted platforms provide users access to telecom fraud detection and prevention tools, full transparency into data, quick setups, recovery routing, scalability and optimization tools. As an example, AVOXI offers automatic and intentional high-security standards. Your network admins don’t have to worry about firewalls or router configurations, firmware updates, periodic security scans or misconfigurations with a CPaaS provider that uses end-to-end WebRTC encryption to ensure a highly stable and secure business communications network.
