by

Vancouver-based Border0 has joined Toronto’s Tailscale, marking a strategic alignment in secure infrastructure access technology. Tailscale CEO Avery Pennarun said the acquisition expands beyond connectivity into identity-based access control, where Border0’s capabilities in authorization, session visibility, and workflow management fit naturally.

Founded by Andree Toonk, Border0 focuses on simplifying secure infrastructure access without adding complexity. The companies first connected at the RSA Conference and later deepened integration at AWS re:Invent. With Border0 already integrated into Tailscale’s platform, the combined offering aims to deliver a more unified, user-friendly approach to secure system access.
