Network Operations at Your Fingertips: Poll, Analyze, and Stabilize at Wire Speed

Explore how JANUS combines 100% on-premise full-stack SNMP polling, native Layer 2 topology correlation, and unified NOC+SOC convergence into an authoritative fabric telemetry platform.

Realize full-stack network observability without node taxes or cloud polling

JANUS Network Monitor delivers continuous, high-fidelity visibility into your physical switches, routers, firewalls, and network links directly within your private operational boundary. Deployed 100% on-premise on standard Ubuntu Server, JANUS continuously monitors interface states, link throughput, hardware vitals, and traffic health without sending topology data or device telemetry to external SaaS vendors. Operating under a flat licensing model, network teams can monitor every switch port, trunk link, and edge gateway across the entire estate without per-sensor or per-node billing penalties.

Deterministic Fabric Telemetry Pillars

Six core operational capabilities engineered for absolute telemetry custody, multi-vendor standards, and rapid hardware-layer containment.

01

Maintain sovereign operational telemetry — completely air-gapped and on-premise

Monitor mission-critical backbone and edge networks without exposing internal device IPs, routing schemas, or interface utilization statistics to multi-tenant cloud platforms. JANUS collects, stores, and graphs all polling metrics and state histories strictly within your local environment, meeting strict air-gap compliance and national data sovereignty mandates.

02

Track multi-vendor infrastructure via universal standards

Eliminate proprietary vendor lock-in. JANUS monitors multi-vendor environments—including Cisco, Juniper, Aruba, Fortinet, and generic enterprise managed switches—using standard protocols: hardened SNMP (v1, v2c, and v3 AES-256) for interface throughput, packet discards, CRC errors, CPU load, and chassis temperature; and proactive ICMP/TCP synthetics for instant outage detection.

03

Detect network anomalies, broadcast storms, and interface flapping

Guard against silent network degradation and operational bottlenecks. JANUS continuously monitors interface error baselines, instantly alerting operators to duplex mismatches, bad cabling (FCS/CRC errors), rapid port flapping, and packet drop spikes before end-users experience application degradation.

04

Harness unified traffic flow and bandwidth analysis

Move beyond basic link utilization percentages. By pairing SNMP interface counters with native flow monitoring (NetFlow/sFlow), JANUS identifies the exact 'top talkers,' protocols, and conversations consuming interface bandwidth, allowing engineers to determine whether a saturated link is driven by routine backups, video streaming, or anomalous lateral transfers.

05

Prioritize capacity planning with historical link utilization metrics

Eliminate guesswork in bandwidth provisioning. JANUS tracks long-term traffic trends and peak usage curves across physical trunks and WAN links, giving network planners the empirical data needed to schedule link upgrades, balance VLAN trunk loads, and optimize route topologies.

06

Bridge network alerts directly to rapid operational containment

Turn network fault detection into immediate intervention. When an interface experiences runaway packet loops, rogue traffic generation, or unapproved device connections, JANUS links the event directly to physical port controls. Operators can disable the switch port, reassign the VLAN, or initiate upstream firewall rules directly from the unified console without switching management tools.
