Security FAQs

Can Tailscale decrypt my traffic and see my data?

No. Devices running Tailscale only exchange their public keys. Private keys never leave the device. All traffic is end-to-end encrypted, always.

Is my traffic routed through your servers?

No. Tailscale routes traffic over the shortest path possible. In most cases, this is a direct, peer-to-peer connection.

In cases where a direct connection cannot be established, devices will communicate by bouncing traffic off one or more geographically distributed DERP relay servers. Your traffic remains end-to-end encrypted when it passes through a relay server, and Tailscale can’t decrypt it.

Will others be able to access my computer?

Tailscale allows you to connect your computer to other devices logged in to the same Tailscale network. Only devices that are permitted to access your computer as defined in ACLs can initiate connections to your computer. You can also locally block incoming connections to your device.

Does Tailscale encrypt my data?

Yes. Tailscale encrypts customer metadata in the coordination server at rest using 256-bit AES and in transit using TLS. Customer data is encrypted in transit using WireGuard.

Does Tailscale back up my data?

Tailscale backs up customer metadata in the coordination server hourly and tests backups at least annually.

Does Tailscale conduct security audits?

Yes. We work with Latacora to conduct regular security audits. These include traditional assessments, but also monitoring, maturity model review, design review and advisory services. On top of that, we also have peer code reviews, automated static analysis checks, and dependency vulnerability scans.

What infrastructure does Tailscale use?

Tailscale’s infrastructure includes the following:

Is Tailscale’s infrastructure multi-tenant?

Yes. Tailscale’s coordination server, which distributes public keys and controls settings, is multi-tenant. This only stores customer metadata and public keys, not data or private keys.

Tailscale’s DERP relay servers, which help establish point-to-point connections, are multi-tenant. These only route encrypted customer data, never unencrypted data.

What data does Tailscale collect?

In order to provide the service, Tailscale collects device information, including OS, hardware, public IP addresses, network routing information, information on the installed Tailscale client, and other device settings. Tailscale also uses user account information, such as email addresses, to authenticate users to their accounts.

See our Privacy Policy for more details on how we collect and use personal information.

Can I opt out of logging?

Tailscale collects customer metadata related to connection attempts, authentication, and routing to help us to monitor and debug networks.

If you opt out of logging, Tailscale may not be able to provide technical support. To learn how to opt out, see Opting out of client logging.

You cannot limit coordination server logs.

Is Tailscale SOC 2 compliant?

Yes. Tailscale has completed a SOC 2 Type II audit covering AICPA’s trust services criteria for security, availability, and confidentiality. Obtain a copy of the report from our compliance page. Note that the report is confidential, and prospective customers will need to contact support and sign an NDA to access the report.

Is Tailscale HIPAA compliant?

HIPAA defines controls for securing health information.

As Tailscale does not store customer data, only metadata, Tailscale doesn’t have any services in scope for HIPAA. US-based healthcare customers do not need and Tailscale does not execute business associate agreements (BAAs) with our US-based healthcare clients.

Tailscale can be a supporting safeguard for your HIPAA-compliant system to provide integrity and encryption for electronic protected health information transmitted over an electronic communications network (HIPAA 45 CFR § 164.312(e)(1)).

Is Tailscale PCI compliant?

PCI DSS defines controls for securing credit card information.

Tailscale does not store credit card information, and instead uses Stripe to securely process transactions. Stripe is certified to PCI DSS Service Provider Level 1, which is the highest level of security certification available in the payments industry.

As Tailscale does not store customer data, only metadata, Tailscale doesn’t have any services in scope for PCI DSS.

Tailscale can be a supporting safeguard for PCI compliance in your cardholder data environment, to encrypt transmission of cardholder data across open, public networks (PCI requirement 4).
