Protecting your Node.js app requires defense at every layer. Here's how SecureNow provides comprehensive runtime security for Express, Fastify, NestJS, and any Node.js framework.
SecureNow's AI models inspect every incoming request to your Node.js app for injection payloads — including SQL, NoSQL (MongoDB), and command injection patterns. Malicious queries are blocked before they reach your database, protecting your Express routes and API endpoints automatically.
Cross-site scripting (XSS) remains one of the top threats to web applications. Our middleware scans request bodies, headers, and query parameters in your Node.js app for XSS payloads, blocking them at the edge before they can execute in your users' browsers.
Malicious bots and credential stuffing attacks target Node.js APIs relentlessly. SecureNow detects bot signatures, enforces intelligent rate limiting per IP and endpoint, and automatically challenges suspicious traffic with CAPTCHAs — protecting your authentication endpoints and API routes.
Layer 7 DDoS attacks can overwhelm your Node.js server even with load balancing. SecureNow provides application-level DDoS protection with smart rate limiting, traffic analysis, and automatic scaling — keeping your Express or Fastify app responsive under attack.
Unlike traditional WAFs that sit outside your app, SecureNow's SDK runs inside your Node.js process, giving it deep visibility into request context, routing, and application behavior. This runtime approach catches threats that network-level security tools miss entirely.
Signature-based security misses new attack vectors. SecureNow uses anomaly detection ML models trained on billions of requests to identify suspicious patterns in your Node.js traffic — catching zero-day exploits and novel attack techniques that traditional tools can't detect.
All protections activate instantly with a single npm install — no code changes required.
Check any IP address for threat indicators, geolocation, ISP details, and security risk score. Powered by our global threat intelligence database.
