Atsign
Atsign is a cryptographic identity and secure communications platform built around the atProtocol, with keys generated at the edge and encrypted data exchanged only between authorized Atsigns.
The Picari read
Atsign provides protocol-level encryption and non-custodial key handling for devices, services, and people using Atsigns and atServers. Its differentiator is that private keys stay on the endpoints, so the infrastructure layer cannot decrypt customer data. It fits IoT, distributed applications, and agentic AI teams that need encrypted peer-to-peer exchange without centralized key custody.
- Organizations prioritizing decentralized, non-custodial key management and end-to-end encryption for IoT, distributed systems, and agentic AI.
- Securing IoT device communications
- Enabling end-to-end encrypted data exchange in distributed systems
- Protecting agentic AI platform communications
- Facilitating secure remote access without VPN complexities
