Introducing the Vercel Web Application Firewall
Vercel introduces a Web Application Firewall that provides transparency and control over the firewall capabilities that have been silently protecting against DDoS and Layer 3/4 attacks, blocking around 1 billion suspicious connections weekly.
In any given week, Vercel blocks around 1 billion suspicious TCP connections, with some days seeing upwards of 7 billion malicious requests. The Vercel Firewall has been silently mitigating DDoS and Layer 3/4 attacks, but it's been operating as a black box with limited transparency.
