NetBird vs Tailscale

NetBird

The terms document optional hosted "Reverse Proxy" services that "facilitate network connectivity between devices, networks, services, or the public internet" on a shared, best-effort basis with quotas and bandwidth limits, and the homepage presents an open-source project with 30.7k stars. We found no public information in the captured pages on clients per platform, the protocol, per-resource access, NAT traversal or gateway and relay locations, so the access model is confirmed only at a basic level.

Tailscale

This is the model I want for sixty servers and two clouds: WireGuard peer-to-peer mesh with STUN/ICE NAT traversal so nothing needs an inbound port, DERP relays only as fallback, and subnet routers bridging whole subnets including site-to-site between cloud networks. Clients are listed for Windows, macOS, Linux, iOS, Android, Chromebooks and more, MagicDNS and split DNS are documented, the Kubernetes Operator covers clusters, and high-availability subnet routers with failover are written up. We found no public information on always-on auto-connect, clientless browser access for contractors, or post-quantum key exchange, so it stops short of the top end.

NetBird

The privacy policy shows user authentication running through Auth0 in the USA under standard contractual clauses, and the trust page lists role-based access control, multi-factor authentication and user access reviews as established controls — a basic identity layer. We found no public information in the captured pages on single sign-on with Entra ID, Google Workspace or Okta, SCIM deprovisioning, per-resource policies, just-in-time access or device posture checks.

Tailscale

Authentication is outsourced to your own OAuth2/OIDC/SAML provider with MFA inherited from it, SCIM group sync keeps access current, and policies are default-deny grants in one tailnet policy file I can drive through GitOps with GitHub or GitLab and the API. Device posture pulls pre-populated host facts plus synced EDR and MDM attributes (CrowdStrike is the worked example), just-in-time access is policy-file driven, and Tailscale SSH authorizes by tailnet identity instead of SSH keys — the shared bastion key can finally die. Terraform shows up for managing PAM resources rather than the whole tailnet, which is the one gap I care about.

NetBird

We found no public information on connection or access logs, admin audit logs, retention periods, SIEM streaming or session visibility in the captured pages. The trust page's access reviews and tested incident-response plan describe organizational controls rather than customer-facing logging.

Tailscale

Configuration audit logs are on by default with actor, action, target and time, filterable in the admin console and exportable via API, and network flow logs cover node-to-node traffic with an explicit statement they contain no traffic contents. Streaming to named SIEMs — Splunk HEC, Datadog, Elasticsearch, Panther among others — plus webhooks and SSH session recording is documented, and every connection being logged on both source and destination makes tampering detectable. Configuration log retention is fixed at ninety days and cannot be configured, and we found no public information on alerts for unusual access or a live session view.

NetBird

Support channels are named — Slack, GitHub and a NetBird status page, with defects reported by email — customers get an account with self-service cancellation, maintenance is capped at two hours a week, and role-based access control is listed on the trust page. The documentation set includes public API pages, but we found no public information in the captured pages on client deployment through MDM, configuration as code, a Terraform provider, granular admin roles or multi-tenant set-up.

Tailscale

A documented REST API is on all plans with scoped tokens and trust credentials, admin roles split across Owner, Admin, IT admin and Network admin, MDM deployment written up in real detail for Jamf with preconfigured profiles, and centrally managed client updates across stable, release candidate and unstable tracks. The Kubernetes Operator deploys via Helm, multiple tailnets under one organization exist for OEM-style setups, and webhooks are listed. We found no public information on a self-hosted or on-premises edition documented for production, which is what holds this below the top level.

NetBird

The trust page lists an ISO 27001 official certificate and audit report, a SOC 2 Type II attestation and a 2025 penetration test report, alongside tested continuity and incident-response plans, encryption at rest, in transit and key management, and the site runs a public status page. The homepage presents an open-source project with 30.7k stars while the terms state "the object or source code of the Software will not be disclosed" — the captured pages give different signals on source availability — and we found no published architecture describing what the coordination servers or relays can see, no SLA and no vulnerability disclosure contact.

Tailscale

The how-it-works page is exactly what I ask vendors for: the coordination server is described as a shared drop box for public keys only, private keys never leave the node, and DERP relays blindly forward already-encrypted WireGuard packets and do not log — with the relay code open source so I can check. Encryption is documented down to Noise IK with X25519, TLS 1.2 minimum, AEAD cipher selection and Tailnet Lock signatures, the network stays reachable when the coordination server is down, and DERP regions fail over independently. Independent Latacora audits are stated but available only on request, the vendor states it has no bug bounty program, and we found no public information on a status page, incident history or an availability SLA.

NetBird

NetBird GmbH of Rosenthaler Straße, Berlin, registered at Amtsgericht Charlottenburg, contracts under German law, and the privacy policy commits to processing personal data in the EU/EEA with AWS limited to EU/EEA servers for application hosting. Subprocessors are listed with addresses, purposes and safeguards — though user authentication runs through Auth0 in the USA under standard contractual clauses, and marketing analytics reach Cloudflare, HubSpot, Microsoft Clarity and Reddit in the USA, some without a stated safeguard. A data processing agreement is declared applicable and ISO 27001 and SOC 2 Type II are stated, which lands this just short of a fully sovereign chain.

Tailscale

The contracting entity is a US corporation with exclusive venue in New York County, while the DPA is published with standard contractual clauses, an Article 27 GDPR representative (EDPO) appointed, and subprocessors listed with ten days' notice of changes. Information is stated to be maintained and processed in Canada, Germany, the United States and the United Kingdom — a mixed footprint rather than a documented EU-hosting option for the control plane and logs — and we found no public information on a self-hosted production edition that would keep records on our own servers.

NetBird

The terms confirm a package-based service — "The provided scope of the Services depends on the package the Customer subscribes for" — with reverse proxy features possibly subject to usage-based pricing, bandwidth limits and fair-use policies, an indeterminate term cancellable by month's end on fourteen days' notice, and self-service cancellation from the account. We found no public price per user or device, tier inclusions, minimum seats or self-hosted licence price in the captured pages, so a real annual cost cannot be computed from them.

Tailscale

Published tiers are Personal at $0 forever, Standard at $8 per user, per month and Premium at $18 per user, per month, with tagged resources at $1 per month each beyond fifty included, per-plan ephemeral-minute allotments, taxes explicitly excluded, USD invoicing at thirty days, and plan gating documented for posture attributes and log streaming. Enterprise and additional ephemeral minutes are contact sales. Minimum seats, minimum term and an annual-versus-monthly price difference are the pieces we found no public information on.
