Securing web applications is core to the Vercel platform. It’s built into every request, every deployment, every layer of our infrastructure. Our always-on Denial-of-Service (DoS) mitigations have long run by default—silently blocking attacks before they ever reach your applications. Last year, we made those always-on mitigations visible with the release of the Vercel Firewall , which allows you to inspect traffic, apply custom rules, and understand how the platform defends your deployments. Now, we’re introducing Protectd , our next-generation real-time security engine. Running across all deployments, Protectd reduces mitigation times for novel DoS attacks by over tenfold , delivering faster, more adaptive protection against emerging threats. Let's take a closer look at how Protectd extends the Vercel Firewall by continuously mapping complex relationships between traffic attributes, analyzing, and learning from patterns to predict and block attacks.…
