Frequently Asked Questions
Get answers to common questions about ZWall's features, implementation, and performance.
ZWall is a next-generation firewall built on eBPF/XDP technology that operates at the kernel level. Unlike traditional firewalls that process packets in userspace, ZWall processes traffic directly in the kernel, achieving sub-microsecond latency and handling millions of packets per second. This results in 10-100x better performance compared to conventional solutions while maintaining enterprise-grade security features.
ZWall requires Linux kernel 4.18+ with eBPF/XDP support. Recommended specifications:
- • CPU: 4+ cores, x86_64 architecture
- • Memory: 8GB+ RAM (16GB+ for high-traffic environments)
- • Network: 10Gbps+ network interfaces for optimal performance
- • Storage: 50GB+ SSD for logs and configuration
- • OS: Ubuntu 20.04+, CentOS 8+, or RHEL 8+
ZWall implements advanced DDoS protection using machine learning algorithms and behavioral analysis. It can detect and mitigate volumetric, protocol, and application-layer attacks in real-time. The rate limiting engine supports per-IP, per-subnet, and per-service limits with configurable thresholds and automatic blacklisting. All processing happens at kernel level, ensuring protection doesn't impact legitimate traffic performance.
Yes, ZWall is designed for seamless integration. It supports SIEM integration via syslog, JSON, and CEF formats. REST APIs enable integration with orchestration platforms like Kubernetes, Docker Swarm, and cloud providers. ZWall also supports SNMP monitoring, Prometheus metrics, and can forward logs to popular solutions like Splunk, ELK Stack, and cloud logging services.
