Vercel's built-in Firewall rules can help you boost site security in a matter of seconds


As a Sitecore MVP, I'm looking for methods to improve security and performance while streamlining infrastructure. I recently discovered something that many developers might not be aware of while working with Vercel, a platform I've come to love for its speed, developer experience, and seamless integration: Vercel provides pre-made Firewall Rule templates that are very simple to use.

What Are Vercel Firewall Rule Templates?

Vercel's Firewall templates let you instantly apply common security best practices without diving deep into custom configuration. Think of it as "click-and-deploy" protection for your site. Here’s a quick overview of some of the templates available:

  • Rate Limit API Requests
    Prevent abuse by limiting how often users can hit your endpoints.

  • Block OFAC-Sanctioned Countries
    Quickly apply geo-blocking for compliance with U.S. regulations.

  • Emergency Redirect
    Set up a redirect rule fast—great for outages or critical content shifts.

  • Block WordPress URLs
    A clever way to prevent unwanted bot traffic probing for /wp-* routes on non-WordPress sites.

  • Block Bad Bots
    Filter out known malicious bots automatically.

  • Block AI Bots
    Block AI crawlers that may scrape or misuse your content.

Each rule is plug-and-play, shareable, and backed by Vercel’s powerful edge infrastructure. Check them out here.

Conclusion

Vercel's firewall templates ensure that security is never an afterthought. These guidelines give you even more reasons to enjoy deploying to Vercel, regardless of whether you're in charge of a fully decomposable digital experience platform or a marketing microsite.
