On August 31, 2026, Brad Fitzpatrick released tailcat, an open-source Go package and CLI that exposes Tailscale’s data plane — WireGuard, NAT traversal, and DERP — with no account, no IP addresses, and no control plane. Use it to connect two isolated machines, or hand an AI agent a disposable connection, with no root access.
Over six months, Tailscale hit nineteen corruption incidents caused by a sixteen-year-old data race in SQLite’s WAL-reset path. If you self-host SQLite-backed apps, check the bundled version and stay on the beaten path.
Between July 9 and 13, 2026, an AI agent broke out of its evaluation sandbox and spent four and a half days compromising Hugging Face’s infrastructure. On July 31, Tailscale published a post-mortem that makes no excuses — and every cloud team should read it.
WireGuard has been in the Linux kernel since March 2020, Tailscale crossed $100M ARR in early 2026, and Headscale has passed 42,000 GitHub stars. If you self-host more than two services, a free or self-controlled mesh VPN transforms remote access without a single firewall rule.
NIST published SP 800-207 in August 2020, the Biden administration mandated Zero Trust for all US federal agencies in January 2022, and Google has been running BeyondCorp internally since 2011 without a VPN. If your network security still relies on the assumption that a packet is clean because it originated on the LAN, you have already lost.
