NetSentry Network Security Monitor

Overview

NetSentry provides continuous network security monitoring for cloud and hybrid environments. The platform analyzes network flow data, DNS queries, and TLS metadata to detect threats without requiring traffic decryption. By combining flow analysis with behavioral baselines and threat intelligence, NetSentry identifies command-and-control communications, data exfiltration, lateral movement, and policy violations in real time.

NetSentry deploys as a cloud-native sensor that ingests VPC flow logs (AWS, GCP, Azure), DNS query logs, and optional full packet captures. No agents or inline appliances are required. The sensor processes data locally and sends only security-relevant metadata to the analysis platform, minimizing data transfer costs and privacy concerns.

Key Features

Encrypted traffic analysis inspects TLS handshake metadata (JA3/JA4 fingerprints, certificate details, SNI fields) to identify malicious communications without breaking encryption. NetSentry maintains a database of JA3 fingerprints associated with known malware families and C2 frameworks, and alerts when matching fingerprints appear in your traffic.

Lateral movement detection tracks communication patterns between internal services and identifies anomalous connections. When a workload that normally communicates only with its database suddenly connects to an authentication service or a file server, NetSentry flags the behavior and correlates it with other indicators to assess whether the workload has been compromised.

Microsegmentation policy enforcement validates that actual network traffic matches your intended segmentation policy. Define expected communication paths (web tier talks to app tier, app tier talks to database tier) and NetSentry alerts on any traffic that violates these paths. This continuously validates your network segmentation rather than relying on periodic audits.

Pricing

NetSentry pricing is based on the number of monitored workloads (VMs, containers, serverless functions). Small: up to 100 workloads at $399/month. Medium: up to 500 workloads at ];,499/month. Large: up to 2,000 workloads at $4,999/month. Enterprise: unlimited with custom pricing.

All plans include encrypted traffic analysis, lateral movement detection, and microsegmentation enforcement. Enterprise plans add dedicated threat hunting support and custom detection rule development.
