How would you define the success of Tailscale's single sign-on (SSO) integration?

Introduction

Defining the success of Tailscale's single sign-on (SSO) integration requires a comprehensive approach that considers multiple stakeholders and metrics. To address this product success metrics challenge effectively, I'll follow a structured framework covering core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context

Tailscale's SSO integration is a feature that allows organizations to use their existing identity provider (IdP) for authenticating users on Tailscale's secure network solution. This integration streamlines user management, enhances security, and simplifies access control for IT administrators.

Key stakeholders include:

1. IT administrators: Seeking efficient user management and enhanced security
2. End users: Desiring seamless access to network resources
3. Security teams: Focused on maintaining robust access controls
4. Tailscale product team: Aiming to increase adoption and user satisfaction

User flow:

1. Admin configures SSO integration with their IdP
2. Users log in to Tailscale using their existing corporate credentials
3. Upon successful authentication, users gain access to authorized network resources

This feature aligns with Tailscale's broader strategy of providing secure, easy-to-use network solutions for businesses of all sizes. Compared to competitors like ZeroTier or Nebula, Tailscale's SSO integration offers a more streamlined setup process and broader IdP support.

In terms of product lifecycle, the SSO integration is in the growth stage, with increasing adoption among enterprise customers but still room for feature enhancements and market penetration.
