Connect and control field devices anywhere
Field devices, smart products, and edge systems need secure access across disparate networks. Give every device, gateway, service, and data source its own cryptographic identity, bounded authority, and end-to-end encrypted communication with post-quantum protection, without exposing inbound access to protected infrastructure.

// Connected systems should not require custom networking
Connected products rarely live on networks you control. They sit on cellular, inside customer facilities, or behind third-party firewalls. Traditional networking turns every remote connection into a custom IT project full of VPNs, static IPs, and open ports. Atsign replaces that friction with verified identity, and outbound-only communication, keeping your hardware accessible to you while remaining completely invisible to public scanners.

Modernize how your hardware communicates while eliminating the legacy networking hacks that create security debt.

// Common connected-system use cases
Product-to-cloud telemetry
Devices, gateways, and field systems send operational, diagnostic, and status data to authorized applications without exposing inbound services.
Remote diagnostics and support
Engineers, technicians, support tools, and authorized applications connect to specific devices, gateways, or systems when needed, without broad network reach.
Software and configuration updates
Approved updates reach designated devices, gateways, or services without requiring open listening ports or local firewall changes.
Partner and customer environment connectivity
Applications, services, and support teams connect across third-party or customer-managed networks without requiring every site to be reconfigured.
Machine-to-machine communication
Sensors, gateways, applications, services, APIs, and backend systems exchange data through verified identity and post-quantum-protected communication.
AI-enabled edge workflows
AI agents analyze telemetry, trigger diagnostics, and coordinate real-time workflows within defined identity boundaries. See how Atsign and Intel deliver zero-trust security for agentic edge AI with up to 88x hardware acceleration uplift. [Read Intel & Atsign Brief →]
// Where connected systems show up

IP addresses, shared credentials, service accounts
Broad network reach once connected
Static IPs, firewall tickets, port forwarding, local network changes
Manual network updates slow support, diagnostics, and expansion
Exposed services can be scanned, targeted, or used for lateral movement
Verifiable cryptographic identity for every participant
Authorized communication without open inbound access
Scoped access to specific systems, services, data, and actions
Outbound-initiated connectivity across customer, cellular, partner, and cloud networks
New devices, services, and workflows connect through identity and policy
Protected systems remain unreachable to unauthenticated parties
// Built for new systems and deployed infrastructure
Atsign supports both sides of connected-system adoption: building new systems with secure-by-design architecture and post-quantum readiness from the start, and protecting existing systems already deployed in the field.
For new applications, teams can use Atsign AI Architect to model how components communicate, what each participant is allowed to access, and where data is allowed to flow before implementation, then build on Atsign Platform with post-quantum-protected communication.
For deployed systems, NoPorts helps teams add identity-first, post-quantum-protected connectivity to devices, gateways, servers, databases, internal tools, and operational applications without opening inbound ports or redesigning local networks.
// Deploy secure connectivity across your field systems
Connect your device fleets, field gateways, remote support paths, and telemetry pipelines without static IPs, exposed services, or custom firewall rules. Use NoPorts to lock down existing deployments, or design new edge architectures with Atsign AI Architect.
