Vercel

The power of Vercel lies in its ephemeral, serverless architecture, but that fluidity creates a "networking wall" for secure applications. Because Vercel Serverless Functions rotate across massive public cloud IP pools, your application’s outbound identity changes with every invocation. This makes it impossible to connect to firewalled databases, banking gateways, or internal APIs that require a consistent, allowlisted source IP. QuotaGuard provides the persistent identity layer Vercel is missing, decoupling your application logic from the underlying dynamic cloud infrastructure.

• Fixed Outbound Identity for Allowlisting: Assign a dedicated, static IP to your Vercel project so your traffic is always recognized and trusted by destination firewalls. This allows you to scale your serverless functions or redeploy your Next.js app without ever needing to update a partner's security settings.
• Native Environment Variable Injection: No complex networking configuration or sidecars required. Simply inject standard QUOTAGUARD_STATIC_URL variables into your Vercel Project Settings to route outbound requests from your serverless functions through a stable, verifiable IP.
• Secure Database Connectivity: Connect your Next.js frontend directly to restricted SQL databases (PostgreSQL, MySQL, SQL Server) or MongoDB Atlas instances. By routing through a static tunnel, you can access private data sources without exposing your database ports to the open internet or requiring an expensive Vercel Enterprise contract.
• Serverless-Scale Reliability: Our infrastructure is architected to handle the high-concurrency and bursty traffic patterns of serverless environments. We ensure your connections remain stable during rapid scaling events, providing the enterprise-grade uptime needed for critical B2B integrations and financial workflows.
