We’re creating the next generation of Internet technology with simplicity, security, and privacy—built in.

Atsign is a team of diverse, distributed, and dedicated people who are passionate about privacy and security. We created the patented, open-spec atProtocol™, and built the open-source atPlatform™ to enable people, entities, and things to communicate privately and securely over the Internet.

Our award-winning technology is a complete rethink of cybersecurity, one powerful enough to protect critical infrastructure systems and scalable enough to extend that protection to everyone and everything connected to the Internet.
