Vercel Firewall protects your application from DDoS attacks.
Spikes in high volumes of traffic sometimes indicate malicious activity on your site. Customers can now quickly lock down traffic and further protect against DDoS attacks by challenging requests, minimizing the chance that malicious bots get through.
Attack Challenge Mode is now available for all Vercel customers at no additional cost. When temporarily enabled, all visitors to your site will see a challenge screen before they are allowed through.
Learn how to enable Attack Challenge Mode and protect your site.
