Tailscale's Aperture Update Targets AI Tool Lock-In

Tailscale, the Toronto startup that sells VPN software to companies, updated its Aperture platform Tuesday. The goal is to help businesses manage the fast-changing AI tool stack without rebuilding their setup every time a model or provider shifts.

Aperture adds three new capabilities. A chat feature aims to reduce shadow AI use by giving employees a sanctioned interface. Connectors let AI tools access corporate data while preserving user and agent identity. Sandboxed environments give AI agents a controlled workspace to operate in.

“The best model, interface, sandbox, and data connection will keep changing,” Tailscale co-founder and CEO Avery Pennarun said in a release. “Companies should not have to rebuild their AI setup every time one of those pieces changes.”

Pennarun is skeptical that the AI vendor landscape will stabilize soon. The U.S. government's recent decision to suspend foreign nationals' access to Anthropic's Mythos and Fable models drove home the risk of relying too heavily on any single provider. Tailscale positions Aperture as a stable identity and access layer that lets companies swap tools without losing track of who is doing what.

The platform is still in beta. Tailscale closed $230 million CAD in Series C funding last year, driven by demand from AI companies. It now serves more than 30,000 businesses globally. Customers include Microsoft and Nvidia, among others.

Pennarun has described the pressure to adopt AI as a “Wild West” for corporate cybersecurity. Tailscale's first acquisition, Vancouver's Border0, came earlier this year to support that vision. Aperture is the product that ties it together: a control plane for AI access that does not lock the buyer into any one model vendor.
