Executive Summary
Vercel has updated its Firewall to allow users to generate custom Web Application Firewall (WAF) rules using natural language descriptions. Instead of manual configuration, users can now describe the desired behavior, and the Vercel dashboard will automatically create the corresponding rule. This feature simplifies the process of controlling site traffic by blocking, rate-limiting, or challenging requests based on conditions like IP address, path, and country.
Key Takeaways
* Natural Language Input: Users can generate WAF rules by writing a plain-text description of the required behavior.
* Core WAF Actions: The feature supports creating rules to log, block, challenge, rate limit, or redirect requests.
* Supported Conditions: Rules can be triggered by various request attributes, including IP address, path, country, and user agent.
* Example Use Cases: The announcement provides examples such as rate-limiting API requests, blocking access to specific paths like `/wp-admin`, or challenging traffic from outside a specific country.
* Availability: The feature is available now in the Vercel dashboard's firewall custom rules page.
Strategic Importance
This update lowers the technical barrier for implementing advanced application security, making it faster and more accessible for developers to protect their sites without specialized WAF expertise.
