For over 50 years, the internet’s client-server model has relied on open ports, creating massive attack surfaces vulnerable to exploitation. Atsign eliminates this reliance by removing the need for listening ports on devices that hold sensitive data or services. Using our patented, open-source technology, we enable secure, seamless communication for critical systems and organizations—without requiring a major infrastructure overhaul—redefining internet security at its core.

How Atsign Protects Critical Infrastructure

Atsign Platform enables secure, private communication for critical infrastructure by eliminating open ports, using cryptographically verified addresses, and cutting keys at the edge for advanced privacy and security at scale.

How Atsign Platform Outperforms Traditional Cybersecurity

Atsign Platform

Current Cybersecurity Practices

Security Approach

Eliminates reliance on securing network plumbing by removing open ports.

Relies on firewalls, VPNs, and monitoring to secure vulnerable network layers.

Cost Efficiency

Drives administrative and operational overhead to a fraction of that of conventional approaches.

High operational costs and complexity arise from managing firewalls, VPNs, and extensive infrastructure.

Scalability & Adaptability

Enables real-time adaptation for secure ecosystem scaling (e.g., customers, supply chains).

Limited scalability and slow adaptation due to reliance on static, complex configurations.

Resilience (CGNAT/5G)

Built for modern connectivity challenges, including CGNAT and 5G networks.

Struggles with modern connectivity issues due to reliance on legacy methods.

Data Protection & Privacy

Provides end-to-end encryption with cryptographic keys cut at the edge; no data in the clear.

Data may be exposed in transit or at endpoints, requiring additional encryption layers.
