Smart Cities
Securely connect city systems without exposing them.
Atsign EdgeAI helps city services coordinate across departments and providers, with fewer manual handoffs. Securely connect devices, applications, and AI agents while keeping access and approvals under your control.

City services depend on many organizations. Your systems need to work together.
Smart cities bring together public agencies, utilities, private operators, and technology providers, each with their own systems and networks. Services such as transportation, emergency response, and building operations depend on those systems working together.
Each organization needs to control what other systems can access, what they can request, and which changes require approval.
Atsign adds secure connectivity and communication controls to your existing infrastructure. Significantly reduce network setup and administration, keep protected services out of public reach, and let each organization retain control of its own systems.
Protect infrastructure as you connect more systems
Keep protected services out of public reach. Give devices, applications, and agents the communication permissions they need, with the ability to restrict or revoke them.
Get projects into operation sooner
Reduce the firewall changes, VPN provisioning, and site-specific configuration that delay city projects and customer deployments.
Spend less on repeated integration and administration
Use a consistent foundation for secure communication across projects. Reduce one-off network work as you add systems, sites, and partners.
Coordinate the repair. Keep access under control.
Consider a water leak that requires a utility, maintenance contractor, and traffic operator to coordinate a repair:
Detect and confirm
A monitoring system flags a possible water leak. The utility investigates and confirms the problem.
Plan the repair
Maintenance arranges the work and requests any necessary lane closure.
Approve and coordinate
Traffic operations reviews the request and coordinates the approved closure with the repair team.
The organizations involved may use different software, vendors, and networks. Atsign EdgeAI connects their systems through secure, outbound-initiated connections, keeping protected services out of public reach. Each organization controls which connections are allowed.
Bounded authority
Let the utility’s application request a lane closure without granting it control of traffic signals. Traffic operations retains authority over its own systems.
Surgical Kill Switch
If a connected device, application, or agent is compromised, revoke its communication permissions. Target the affected system while preserving other approved connections.
Human-in-the-loop approval and accountability
Require the appropriate team’s approval before operational changes proceed. Record requests, approvals, and actions in an audit journal for authorized review.
Put secure coordination to work across city services.
Traffic and transit
Let authorized transit systems request signal priority and exchange information with traffic applications. Define what each operator can request and which changes require approval.
Energy and EV charging
Connect utility systems with charging infrastructure. Set rules for routine adjustments and require human approval when a proposed change exceeds agreed limits.
Roadside infrastructure and vendor access
Give authorized teams access to signal cabinets, gateways, and remote equipment without exposing protected services. Adjust or revoke communication permissions as personnel, contracts, and operational needs change.
Buildings and facilities
Securely connect building-management applications, gateways, and service providers across sites. Give maintenance teams access to approved systems, with permissions and approval requirements tailored to their responsibilities.
Built around the way your city operates.
Atsign EdgeAI combines endpoint software with an integrated control center, built on Atsign Platform. It connects systems across networks, keeps communications encrypted end to end, and lets authorized teams manage which systems can communicate.
Protected systems initiate connections outward, with no open inbound ports required. Private encryption keys stay with the communicating systems.
From the control center, teams can see connected systems, manage communication policies, and use a granular Kill Switch to isolate compromised devices, applications, or agents.
EdgeAI also includes capabilities for:
Approval workflows
Define what can happen automatically and when a person needs to approve a request.
Audit journals
Maintain a record of requests, decisions, and approvals for authorized review.
Policy replay
Evaluate proposed rules against previous activity before applying them.
Sandboxing
Evaluate software and agent changes in a controlled environment before granting access to operational systems.
Each deployment is tailored to your infrastructure, organizational responsibilities, and operating rules. Your existing applications and chosen AI models provide their capabilities; Atsign helps them communicate and work together securely.
Connect across organizations while keeping responsibilities clear.
For cities, utilities, and infrastructure operators
Bring departments and service providers into shared workflows while controlling access to your systems. Start with a specific operational need and expand as requirements develop.
For technology vendors and system integrators
Build secure communication into your solutions and reduce repeated network configuration across customer deployments. Tailor permissions, approvals, and workflows to each customer’s systems and operating requirements.
Explore our developer examples to start building, or schedule a walkthrough of the smart-city demo to discuss how it could apply to your solution.
Secure communication for intelligent transportation.
Atsign and Intel co-engineered a smart transportation solution that combines secure agent communication with Intel hardware security and cryptographic acceleration.
Explore the joint solution brief for the architecture and performance results.
