Multi‑cloud deployment
One secure network across every cloud
Connect hosts in any cloud, region, or data center as if they were on the same private network. No transit gateways, no VPC peering, and no overlapping-IP headaches.
Multi-cloud networking without the gateways
Connect hosts across any cloud with one overlay instead of per-cloud peering
Per-cloud networking
- Every cloud has its own VPCs, peering, and firewall rules
- Transit gateways and site-to-site tunnels add cost and complexity
- Overlapping IP ranges force painful CIDR planning
- Security policies drift between providers and regions
With Defined
- One overlay network spans every cloud and region
- Direct encrypted tunnels with no transit gateways to manage
- Stable host identities, so overlapping VPC CIDRs do not matter
- One identity-based firewall enforced consistently everywhere
One network across every cloud and region
Bring hosts from AWS, GCP, Azure, and on-prem into a single zero trust mesh
Centralized management
Manage hosts across every cloud and region from one place, instead of juggling each provider's networking console.
Encrypted connections
Hosts automatically establish secure, end-to-end encrypted tunnels to each other, no matter which cloud they run in.
Identity-based access
A built-in, identity-based firewall enforces the same least-privilege rules consistently across every provider.
Connectivity failover
When a direct path between clouds is unavailable, relays maintain encrypted connectivity automatically.
Route to external devices
Routes extend access to appliances and legacy systems that can't run the client, bridging them onto the overlay network.
Tag-based config
Apply configuration and firewall rules through tags to manage thousands of hosts across different clouds at once.

Frequently asked questions
Multi-cloud networking connects the hosts and services you run across different cloud providers, regions, and data centers so they can communicate as if they were on one private network. With Defined Networking, every host joins a single overlay mesh where connections are mutually authenticated with certificates, end-to-end encrypted, and limited to the hosts each one is authorized to reach.
Each host runs a lightweight agent and joins one overlay network regardless of which cloud or VPC it lives in. Hosts establish direct, peer-to-peer encrypted tunnels to each other, so an instance in AWS can reach one in GCP or your own data center without routing through a central gateway.
No. The overlay rides on top of whatever connectivity you already have. Hosts make outbound connections and use UDP hole punching to connect directly, so there are no transit gateways to size, no peering relationships to maintain, and no site-to-site tunnels to configure between providers.
Defined assigns every host a stable address on the overlay network that is independent of its underlying cloud subnet. Because hosts communicate over those overlay addresses, overlapping VPC CIDRs across clouds no longer cause conflicts and you avoid re-planning address space when you add a new cloud or region.
Yes. Any host that can make an outbound connection can join the network, including cloud VMs, bare metal, on-premises servers, and edge devices. The same network spans every provider, so adding a host in a new cloud is the same simple step everywhere.
No. Defined is built on open-source Nebula and runs anywhere, so your network is not locked to a single vendor's primitives. You can move workloads between clouds or add a new provider without re-architecting connectivity.
Instead of stitching together per-cloud security groups, Defined enforces a single identity-based firewall across the whole network. Every connection is authenticated by identity and authorized by built-in host firewall rules, so the same least-privilege policy applies consistently no matter which cloud a host runs in.
Yes. You can connect up to 100 hosts for free with no credit card required, which is enough for most teams to connect their first few clouds before scaling up.
