Serverless IP Allowlisting and Blocking

Many teams need to restrict API access to known networks or trusted clients, but implementing IP allowlisting/blocking across distributed services is error-prone and difficult to audit. Without centralized enforcement, unauthorized traffic can still reach application layers, increasing risk and operational burden.

DevionixLabs delivers serverless IP allowlisting and blocking to enforce access control at the edge of your API. Instead of scattering rules across multiple components, we implement a single, maintainable policy layer that evaluates incoming requests against your allow/block lists before they consume compute or reach sensitive systems.

What we deliver:
• A serverless IP allowlist/blocklist policy integrated into your API gateway layer
• Secure rule management approach for updating IP sets without risky redeployments
• Clear handling for edge cases (missing IP, malformed headers, trusted proxy behavior)
• Audit-friendly logging of access decisions to support compliance and incident response
• Testing and validation to ensure rules behave correctly across environments

How it solves your problem: DevionixLabs ensures only approved IP ranges can access your APIs (or that known-bad ranges are blocked), reducing exposure and improving security posture. Enforcement at the serverless edge lowers the chance of unauthorized requests reaching downstream services.

We also help you define the correct trust model for client IP extraction—especially when traffic passes through proxies or load balancers. That prevents attackers from spoofing headers and ensures your rules evaluate the correct source.

The result is a tighter security boundary with operational clarity. Your team gains a policy layer that is easier to maintain, easier to audit, and safer to change as your trusted networks evolve.

By the time we finish, you’ll have a production-ready access control system that reduces risk, supports compliance needs, and keeps your APIs available for legitimate users.
