Features Comparison
Gcore Web Application and API Protection
-
AI-Driven WAF
WAF using regex, signatures, heuristics, and behavioral analytics to protect against OWASP Top 10 and beyond. Custom rules and device fingerprinting for advanced detection.
-
Bot Management
Distinguishes good bots from malicious ones using behavioral analytics, JavaScript challenges, CAPTCHA, session management, and rate limiting.
-
L7 DDoS Mitigation
Application-layer DDoS protection with burst identification, AI-based IP filtering, and auto-scaling at the edge.
-
API Security
Protects APIs against OWASP API Top 10 with ML-based filtering, JA3 fingerprinting, and heuristic analysis.
-
Edge Deployment
All processing happens at Gcore's 180+ edge PoPs for minimal latency impact on legitimate traffic.
-
Auto-Learning
Self-tuning capabilities that adapt protection rules based on observed traffic patterns and new threat types.
NAXSI
-
Scoring-Based Detection
Assigns scores to suspicious patterns in requests. Blocks when the cumulative score exceeds a threshold, rather than relying on exact signature matches.
-
Learning Mode
Monitors traffic and automatically generates whitelist rules for legitimate application behavior, reducing manual tuning effort during initial deployment.
-
Virtual Patching
Apply custom rules to block specific vulnerabilities without modifying application code. Rules target raw requests or specific fields like headers, args, and body.
-
Deny-by-Default
Operates like a DROP firewall. Common attack characters and patterns are blocked unless explicitly whitelisted for the target application.
-
Lightweight Footprint
Written in C with only libpcre as a dependency. Adds minimal overhead to NGINX request processing.
-
Dynamic Module Support
Can be compiled as a dynamic NGINX module, allowing it to be loaded without recompiling NGINX from source.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
Gcore Web Application and API Protection
- You need: Organizations wanting an affordable full WAAP platform, teams already using Gcore CDN, companies needing combined WAF and API security, globally distributed web applications
- You're using: Cloud (SaaS), infrastructure-agnostic (any origin)
NAXSI
- You need: Teams already running NGINX who want lightweight inline WAF protection, budget-conscious deployments, applications with predictable request patterns, virtual patching use cases
- You want to start with a free tier
- You prefer open-source solutions
- You're using: NGINX, Linux (Debian, Ubuntu, CentOS), FreeBSD, OpenBSD, NetBSD, Docker
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
Frequently Asked Questions
Which is better for startups: Gcore Web Application and API Protection or NAXSI?

Gcore Web Application and API Protection scores higher for ease of use (4.0/5), which is valuable for smaller teams. Consider your immediate security needs and growth plans when choosing.
Which has better support: Gcore Web Application and API Protection or NAXSI?
Gcore Web Application and API Protection has a higher support rating (3.7/5) compared to NAXSI (2.5/5). However, support quality can vary based on your plan tier - enterprise customers typically receive more responsive support from both providers. Consider evaluating support during a trial period.
Which is easier to implement: Gcore Web Application and API Protection or NAXSI?
Gcore Web Application and API Protection scores higher for ease of use (4.0/5) versus NAXSI (2.8/5). The actual implementation effort depends on your existing infrastructure and team expertise.
Which is more cost-effective: Gcore Web Application and API Protection or NAXSI?
NAXSI offers a free tier while Gcore Web Application and API Protection requires a paid plan. NAXSI scores higher for value (4.5/5). Total cost depends on your traffic volume, required features, and support level needs.
What's the difference between NAXSI (open source) and Gcore Web Application and API Protection (commercial)?
NAXSI is open source, which means you can inspect the code, customize it, and self-host without licensing fees. Gcore Web Application and API Protection is a commercial solution with managed support and regular updates. Open source is ideal if you have in-house expertise and want full control. Commercial solutions are better if you prefer managed security with vendor support.
