Graphiant and Tailscale provide "secure connectivity," at different layers and solve different problems.
Graphiant is a managed WAN service with a unique stateless backbone architecture for solving the overlay and the underlay.
Tailscale is an identity-based overlay between endpoints.
Architecture
Graphiant connects sites, clouds, and partners to a provider-operated core via an appliance or virtual machine, and Graphiant software in the internet core carries the traffic. The core is multi-tenant global network fabric and stateless, offering any-to-any connectivity between locations acting as a middle ground between MPLS performance and internet flexibility, competing with traditional MPLS and SD-WAN.
Tailscale builds private networks by orchestrating WireGuard tunnels directly between devices, with a control plane handling keys, coordination and policy while the data plane stays end-to-end WireGuard; when NAT or restrictive networks block a direct path, traffic falls back to relays. Tailscale rides the public internet and does not interact with the underlay networks.
Differences
Tailscale | Graphiant | |
|---|---|---|
Unit of connectivity | Device/user | Site, cloud VPC, partner |
Transport | Public internet | Public internet, private peering, cloud interconnects, provider-operated backbones |
Bought by | Platform/DevOps teams | Network/WAN/Security teams |
Deployment | Install client, log in with SSO | Appliance or virtual machine per site, or browser client provisioned via portal/API |
SLAs | Support SLAs; no path SLA (internet-dependent) | Bandwidth, Quality of Service (QoS) and delivery SLAs |
Pricing | Per user per month, free personal tier, paid tiers from around $6/user, custom enterprise | Aggregate Bandwidth subscription |
Strengths | SSO with SCIM provisioning, device tags, ephemeral keys for just-in-time access, subnet routers and exit nodes for hybrid cloud without renumbering, MagicDNS, native SSH | Multicloud and B2B/partner connectivity, data-in-motion controls and path/geography policy, predictable performance |
Weak spots | No deterministic performance; ACL errors cause issues ; exit nodes aren't a secure web gateway | Hardware/VM at each site, longer sales and onboarding cycle, less useful for individual laptops |
How to choose
Pick Tailscale if the problem is "engineers and workloads need to reach things across clouds and machines without a VPN concentrator".
Pick Graphiant if the problem is "we have branches, data centers, cloud regions, and partners that need reliable any-to-any connectivity with contractual performance and control over where data flows", especially if you're evaluating MPLS or SASE/SD-WAN.
In larger organizations they coexist: the WAN service carries site and cloud traffic, while the mesh overlay handles per-workload access.
