See everything on your network.
Know what's normal. Detect what's not.
NetWatch combines behavioral traffic analysis — jitter scoring for low-and-slow C2 beacons, entropy detection for DNS tunneling, east-west connection analysis for lateral movement — with full-protocol inspection, signature-based IDS, passive asset discovery, and full PCAP capture. One platform that produces signals analysts can act on.
Core Capabilities
Four integrated engines working together to give you complete network visibility and threat detection without the noise.
Behavioral Traffic Analysis
Statistical analysis of connection patterns in the sensor's structured logs -- jitter scoring catches low-and-slow C2 beacons, entropy and query-volume analysis catches DNS tunneling, east-west connection graphs surface lateral movement, and outbound volume anomalies flag data exfiltration.
Full-Protocol Network Sensor
Full protocol analysis, connection logging, DNS monitoring, SSL/TLS inspection, and Community ID correlation across all monitored traffic.
Signature-Based IDS
49,000+ emerging-threat detection signatures with real-time alert streaming and protocol detection. Continuously updated rulesets tuned for enterprise environments.
Passive Asset Discovery
Automatic network inventory built from traffic observation. No agents, no scanning, no network disruption -- just visibility from what is already on the wire.
Behavioral Analysis Deep Dive
Statistical analysis of connection patterns -- timing, volume, entropy, and destination graphs -- goes beyond signatures to detect adversary behavior that blends into normal traffic.
C2 Beacon Detection
Jitter scoring algorithm identifies periodic callbacks even with randomized intervals. Detects low-and-slow beaconing that signature-based tools miss.
DNS Tunneling
Entropy analysis combined with query volume anomaly detection catches encoded data channels hidden in DNS traffic.
Lateral Movement
Internal connection pattern analysis identifies east-west spread across your network, surfacing attacker pivoting behavior.
Data Exfiltration
Outbound volume anomaly detection and unusual destination tracking identify data leaving your network through unexpected channels.
Infrastructure Intelligence
Automatically separate signal from noise with scanner identification and infrastructure traffic filtering.
Known Scanner Identification
GreyNoise-powered tagging identifies Shodan, Censys, and other known scanners automatically -- reducing noise and surfacing real threats.
Infrastructure Traffic Filtering
Nythrix infrastructure traffic is hidden from client views via BPF filters and tagging. You see your network, not ours.
PCAP Capture
Full packet capture with automatic rotation and BPF filtering for relevance. 24-hour retention provides forensic-ready evidence for incident investigation and regulatory compliance.
