} char _license[] SEC("license") = "GPL"; - Suricata: Strong at pattern matching (signatures) but can struggle with high-speed encrypted traffic without massive hardware.
- Zeek: Exceptional for protocol analysis and logging, but requires significant post-processing to turn data into actionable alerts.
- HookProbe NAPSE: An AI-native engine designed for the edge. It combines the best of signature-based logic with behavioral AI models, running within the 7-POD architecture to ensure low-latency detection across IoT and enterprise networks. - Audit Your Data Ingest: Identify high-volume, low-value logs (e.g., firewall 'allowed' logs) and move their analysis to the edge using HookProbe.
- Implement Tierless Triage: Use AEGIS to automatically close low-risk alerts, leaving only high-context incidents for your senior analysts.
- Deploy Edge-First IDS: Utilize HookProbe agents on existing infrastructure to avoid the 'Data Wall' associated with centralized packet capture. Refer to the documentation for deployment strategies.
- Automate Incident Response: Transition from manual ticket creation to autonomous kernel-level blocking for known malicious patterns.
