How Network Discovery with NetCrunch Transforms Your Cybersecurity Risk Assessment

You can't secure what you can't see. NetCrunch turns visibility into actionable cybersecurity intelligence.

Why Visibility Is Step One of Security

Blind spots in your infrastructure lead to vulnerabilities. Up to 60% of security breaches stem from unmanaged or unknown assets. Without network discovery, you can't:

• Maintain an accurate inventory
• Identify rogue devices
• Detect misconfigurations early
• Map real exposure to threats like CVEs

NetCrunch solves this with continuous, policy-driven discovery across your infrastructure.

The NetCrunch Discovery Advantage

Unlike tools like PRTG that rely on manual sensor setup, NetCrunch automatically:

• Scans entire IP networks, AD domains, subnets, and VLANs
• Classifies over 670+ device types using SNMP, WMI, CDP, LLDP, and MAC address tables
• Assigns monitoring packs based on OS, vendor, or role
• Visualizes logical and physical topology
• Updates maps and dashboards dynamically

You gain real-time observability without configuration sprawl.

Cyber Risk Impact: More Than Just Inventory

Discovery isn't just for inventory reports — it's foundational to:

• Baseline Behavior Analysis
  Track regular service and network behavior. Deviations become signals.

• Vulnerability Prioritization
  Match new CVEs to live systems. No more guessing where you're exposed.

• Automated Alert Readiness
  Newly added devices are immediately monitored and subject to your alerting policies.

• Visibility into Shadow IT
  Detect IoT, rogue APs, personal devices, or legacy OT components hiding in your network.

Advanced Discovery for OT and Hybrid Environments

Where others stop, NetCrunch adapts:

• Layer 2 Diagrams: Map physical switch connections
• Auto VLAN & Port Mapping: For accurate segmentation auditing
• Device Config Snapshots: Track config drift over time (e.g., routers, firewalls)
• SNMPv3 & Custom MIBs: Add non-standard or vendor-specific hardware

Cloud? Remote sites? No problem:

• Discover AWS, Azure, and GCP nodes
• Extend discovery via remote probes across NAT or firewalled sites
• Secure with built-in HTTPS relay (NCC)

From Detection to Protection: NetCrunch in Action

Once devices are discovered, NetCrunch does more than display them. It actively protects your infrastructure via:

Feature	Security Value
Real-Time Maps	Spot topology changes instantly
Monitoring Packs	Enforce consistent config and alerting across roles
Alerting Engine	Correlate SNMP, Syslog, WMI, traps, and thresholds
Access Policies	Define who sees what with RBAC per user/view
Status Views	Focus on nodes with issues, not noise
Logs & Trend Analytics	Surface patterns behind alerts

No Sensor Limits. No Guessing Costs.

NetCrunch uses node + interface licensing, not per-metric sensors. You always know:

• How many devices you licensed to monitor
• What counts as a monitored interface
• That you can monitor everything about a node (CPU, memory, apps, logs) under a single license

Compare this to tools like PRTG, where monitoring one switch port's traffic + errors + discards + VLAN = 4 sensors = 4x license cost.

Enhancing Cybersecurity Compliance

NetCrunch makes audit prep easy:

• Export inventory and change logs
• Track configuration versions
• Log user actions, alert history, and events
• Enforce role-based views to meet separation-of-duty requirements

Supports frameworks like:

• NIST 800-137 (ISCM)
• ISO/IEC 27001
• ITIL Monitoring Best Practices

Getting Started: Secure Your Visibility

1. Run Auto-Discovery
   Start with local subnets, AD, or import known nodes.
2. Set Credentials
   Apply shared or per-node SNMP/WMI/SSH profiles. NetCrunch will match devices automatically.
3. Review Node Roles
   Confirm device types. NetCrunch will assign appropriate monitoring packs.
4. Expand & Integrate
   Add cloud nodes, remote probes, or telemetry sources. Push data into SIEMs or ITSM tools.
5. Monitor, Alert, Harden
   Use NetCrunch alert templates to enforce uptime, config baselines, and detect suspicious behavior.

Frequently Asked Questions

How often does NetCrunch scan?

It continuously updates maps and detects new devices in real-time or on schedule. You can also trigger rescans manually or via API.

Does it discover cloud and remote devices?

Yes. NetCrunch discovers and monitors AWS, Azure, and more using native APIs. Remote sites are supported via probes or a secure HTTPS tunnel.

How does licensing work?

Licensing is based on nodes and interfaces. One node license includes complete monitoring, and one interface license includes traffic, errors, discards, VLAN, and port mapping.

Is it better than PRTG?

Yes, especially at scale. NetCrunch has:

• No sensor count limitations
• Real Layer 2 and Layer 3 topology discovery
• Full-stack monitoring packs
• Real alerting engine with correlation
• No UI split or clunky configuration

PRTG does not support native Layer 2 or Layer 3 discovery. NetCrunch builds live topology maps using switch port data, neighbor protocols, and routing relationships out of the box.
