WAF Integration for Serverless APIs

Your serverless APIs are constantly probed by automated traffic—credential stuffing attempts, injection payloads, broken access patterns, and protocol abuse—while traditional perimeter defenses don’t reliably cover ephemeral serverless endpoints.

DevionixLabs integrates a Web Application Firewall (WAF) designed for serverless APIs so malicious requests are filtered before they reach your functions. We configure rules that match your API behavior, reduce false positives, and enforce consistent protection across versions, stages, and routes.

What we deliver:
• WAF policy configuration tailored to your API endpoints and threat model
• Managed rule sets with safe tuning to minimize disruption
• Custom protections for common API risks (e.g., injection patterns and abusive request shapes)
• Integration guidance for serverless gateways and routing layers

We begin by analyzing your API surface: authentication methods, request/response formats, rate limits, and typical payload sizes. Then we implement WAF rules that align with your real traffic patterns, including protections for malformed requests and suspicious query/body structures.

DevionixLabs also supports a staged rollout approach—starting in detection mode, validating logs, and then moving to enforcement once rule accuracy is confirmed. This helps your team avoid breaking legitimate clients while still improving security posture quickly.

BEFORE vs AFTER results typically show fewer successful malicious attempts, improved request hygiene, and more actionable security telemetry for your engineering and security teams.

Outcome: You get a serverless API environment with WAF coverage that blocks common web attacks at the edge, improves visibility into threats, and strengthens reliability for legitimate consumers—without sacrificing developer velocity.
