What is Communication Platform as a Service?

Communication platforms as a service provide highly customizable communications infrastructure and tools for development teams to build custom, front-facing applications for their customers as well as create new communication capabilities for existing applications.

CPaaS enables development teams to connect their applications to SMS, voice, and verification features through APIs (application programming interfaces). These communication capabilities include text notifications, voice connectivity, and user-to-user chatting.

However, CPaaS goes beyond basic communication functionality to provide features such as multi-factor authentication (MFA) via email and text.

How to Choose a CPaaS Provider

To ensure you select the best CPaaS provider for your organization, there are a few considerations to make.

  • Global Reach: The features offered by a provider may vary around the world. If your organization has to extend communications into foreign markets and satisfy customers on their preferred platforms, then you should prioritize vendors with highly reliable networks and global reach. 
  • Enterprise-Grade Security: Providers in consideration should offer enterprise-grade security through encryption of information sent through their APIs. The provider must also ensure data at rest and in transit is secure through encryption and security measures.
  • Compliance: An understanding of each provider’s offering helps to understand the sectors in which the provider is compliant. Your prospective provider should be aligned with your compliance requirements.
  • Technical Support: Technical support is key to ensuring development teams are not hampered by technical challenges. You should consider providers with highly effective and available technical support teams.
