Advanced egress firewall filtering for Vercel Sandbox
2 min read
Vercel Sandbox now enforces egress network policies using SNI filtering and CIDR blocks. Outbound TLS connections are matched against policies at the handshake, blocking unauthorized destinations before data transmits. Default unrestricted access can be locked down for untrusted or AI-generated code, preventing data exfiltration and unintended API calls.
