Connect Everything.
Expose Nothing.

The internet was designed to be open. Connectivity came first, and individual organizations were left to defend themselves. Today, teams try to protect their complex digital networks by stacking complex, bolt-on security controls on top of that open foundation. It’s not working.

Atsign offers a different approach. We provide the missing layer that allows all of these entities to connect and collaborate with the very best defense of all: no public network attack surface.

Atsign brings together a focused, elite team with decades of specialized experience across networking, cybersecurity, cloud, and open source. We’ve spent our careers solving the internet’s toughest connectivity and security challenges.

Where our team has engineered the past:

Security & Infrastructure:
Akamai • Palo Alto Networks • F5 • Juniper Networks • Cohesive Networks • Google Cloud

Enterprise & Telco:
British Telecom • DXC Technology

Global Finance:
Credit Suisse • Deutsche Bank • UBS

While true end-to-end encryption relies on unique keys to guarantee cryptographic trust, the platform is only as strong as its architects. Our technology represents half of the equasion—the collective enterprise security experience of our team completes it..experience of the people behind it.

Just as our technology requires verification before any connection is made, we hold our platform to the same uncompromising standard. We do not ask for implicit trust. We verify it through open source transparency, rigorous testing, and real-world results.
