Addition By Subtraction

Vercel Security Checkpoint is a browser verification layer designed for site owners who need to stop automated threats without degrading the user experience. It intercepts incoming requests and presents a quick challenge to confirm the visitor is using a real browser, effectively filtering out bots, scrapers, and other non-human traffic before they can access your content.

• Browser verification challenge: Automatically presents a lightweight test to visitors, ensuring only genuine browser traffic passes through.
• Bot and scraper blocking: Stops automated scripts, credential stuffing attempts, and content scrapers at the edge, reducing server load and protecting your data.
• Minimal performance impact: The challenge completes in milliseconds, so legitimate users experience no noticeable delay.
• Edge-level enforcement: Runs on Vercel's global edge network, blocking threats close to the source before they reach your origin server.
• Simple setup: Activates with minimal configuration, requiring no code changes or complex rule writing to start protecting your site.
