• Ethernet, IP/UDP/TCP/ICMP filtering
• Extremely low latency; tests show improved network throughput underload by blocking packets earlier
• API for event logging
• Easily configurable filtering rules:
- Static/rules-based filtering
- Dynamic filtering/stateful packet inspection (SPI) blocks packets based on connection state
- Choose your firewall package based on application requirements – see table below
