# Vercel deployment protection is free: lock previews and production without the add-on

On September 9, 2026, Vercel published [Protect production deployments for free on every plan](https://vercel.com/changelog/protect-production-deployments-for-free-on-every-plan). The claim is direct: **Vercel Authentication can protect all deployments in a project, including production, at no additional cost on every plan.** Previously, protecting production domains required the $150-per-month Advanced Deployment Protection add-on.

If you ship SaaS or internal tools on Vercel, that changes the cost math before launch. You no longer need to treat production URL gating as a paid add-on decision for Vercel Authentication.
