Think of PubNub as a Content Delivery Network (CDN), but for the streaming web. While a CDN is designed to serve static content (i.e. ‘data at rest’), a Data Stream Network (DSN) is optimized for serving dynamic content (i.e. ‘data in motion’), in realtime.
PubNub can be used to quickly push small messages to one or more devices (smartphones, browsers, microcontrollers, tablets, etc.) – essentially, just about any device that can make a TCP/IP connection to the internet – as well as back again, for bidirectional communication between devices.
PubNub DSN provides rich authorization, authentication, encryption, and legislative
security encircling every level, from network to user.
TLS and AES256 encryption, plus support for BYOE (bring-your-own-encryption) models.
PubNub Access Manager delivers fine-grain access control for every device and every channel.
PubNub Functions support flexible authorization schemes via any OAuth and LDAP model.
No inbound open ports and instantaneous routing to different data centers to thwart regional attacks.
HIPAA Compliance, SOC 2 Compliant, Data Shield certified, and EU-only Data Storage options.
Low-latency realtime messaging anywhere in the world. PubNub processes 5x the data that Twitter does, and that number only continues to grow.
No compatibility headaches. With over 70 SDKs, from mobile and web to embedded, PubNub works across all devices and apps, on all types of networks.
Let our 9s do the talking. Build your app with PubNub, and sleep easy at night knowing that scale, latency, data durability, and security are rock solid.
