Common Mistakes to Avoid
Several recurring pitfalls across these tools create false positives, weak detections, or heavy operational overhead.
Treating signature-only network rules as sufficient
Snort and Suricata both rely on rule-based detection and protocol decoders, but false positives rise when rules are not tuned to real traffic patterns. Zeek and Trellix Network Security improve detection reliability when they add protocol-aware event generation or threat-intelligence-driven correlated context.
Underestimating tuning and policy setup effort
Cortex XDR, Falcon, Elastic Security, and Wazuh all require time to tune detection logic and policy or rule design for accurate results. Suricata, Snort, Zeek, and Security Onion also require ongoing rule management and operational discipline for meaningful alerting.
Choosing a platform layer that does not match your end goal
Amazon Security Lake centralizes and normalizes AWS telemetry, so it cannot replace an IDS alert engine when you need direct intrusion alerts. Elastic Security can supply detection over those logs, while Security Onion supplies an integrated network and host detection stack.
Ignoring the investigation workflow that turns alerts into outcomes
Trellix Network Security and Cortex XDR provide investigation support with contextual enrichment, but they need analyst training to use alert review workflows effectively.
