Tailscale initially launched in 2019 as a VPN provider using open-source technology from WireGuard. Since then, it has expanded significantly, recently announcing a series of new capabilities at the Tailscale Up conference. This includes a DNS filtering service from Control D and Tailscale PAM, a privileged access management tool.
With a $160 million investment secured last year, Tailscale is redefining private connectivity in the AI-driven landscape. Unlike traditional VPNs that assign access based on IP addresses, Tailscale bases access on user identity, applying policies related to that identity. This identity-centric approach serves as the foundation for its new services.
The notable new services include:
- DNS Filtering by Control D: This service integrates directly into Tailscale, allowing for filtering of malicious domains through Tailscale’s policy engine.
- Tailscale PAM: Currently in beta, this tool enables teams to manage privileged access without distributing static credentials, effectively improving security for sensitive infrastructures.
- Aperture: Tailscale’s AI gateway, which ensures AI agents maintain an identity on the Tailscale network, facilitating secure communication and actions within the network.
- Aperture Plus: A web-accessible tool that allows users to operate without a system-level VPN installation, managing multiple workspaces simultaneously.
- Tailcat: An open-source mesh network solution without centralized control.
- Developer APIs and SDKs: New programming tools that enhance software development on Tailscale’s identity framework.
In his keynote at the conference, Tailscale’s co-founder, Avery Pennarun, made an evocative comparison to Greek mythology, likening certain large tech companies to deities hoarding power over AI infrastructure. He expressed a mission to reclaim this power for broader access, stating, “Maybe it’s like Zeus, maybe they stole the fire from us in the first place. So, together, we’re going to steal it back.”
Tailscale’s improvements address the dual challenge of secure connectivity and controlled access, taking a step beyond simple device connection. The DNS filtering by Control D efficiently prevents access to harmful domains, while Tailscale PAM streamlines access management for various sensitive resources.
Further, the launch of Aperture aims to redefine VPN access by creating a secure identity model for AI agents, facilitating their activities without compromising security protocols. This expansion into AI illustrates Tailscale’s commitment to adapting to emerging technological challenges while maintaining their core identity-based access principles.
Finally, Tailscale is opening its platform to developers with new SDKs for Rust, Python, C, C++, and Elixir. The Tailnet Creation API allows for automated setup of isolated networks for development and testing, enhancing collaboration efficiency.
In summary, Tailscale is evolving from a VPN-centric model into a robust connectivity platform that incorporates advanced security measures for both human and AI actors within its network.
