Products

Three focused products for everyday network operations.

01

mini-noc VPN Auth

A central identity service for VPN gateways: accounts, OTP, RADIUS/LDAP, and audit logs.

Deploy once, then connect Palo Alto, FortiGate, and other RADIUS clients to the same directory. Supports dual authentication paths: PAP with OTP for SSL-VPN, and MSCHAPv2 for IPsec when required by the gateway.

  • User and group management with LDAP directory
  • OTP (TOTP) for supported VPN paths
  • FreeRADIUS integration for Palo Alto, FortiGate, and similar clients
  • Authentication logs and system health dashboard
02

mini-noc Quota Manager

See bandwidth usage clearly, then apply policy when limits or abuse appear.

Find who is using capacity, inspect live flows, and enforce block or DNS rules when needed. Designed for daily operations, not only monthly reports.

  • Usage query and traffic analytics
  • Live flow tap and block lists
  • Rule management and DNS denylist
  • User admin, settings, and audit trail
03

mini-noc network monitor

A lightweight network monitor with ICMP/TCP/DNS/HTTPS/SNMP checks, SNMP charts, status pages, alerts, and Prometheus metrics.

Operate from a web console: manage hundreds of monitors, poll SNMP interfaces, notify by email or Telegram, publish a status page, and expose mini_noc_* metrics for Prometheus and Grafana.

  • Dashboard with host resource summary and monitor health counts
  • Monitor types: ICMP, TCP, DNS, HTTPS, and SNMP
  • SNMP interface discovery, traffic charts, and performance series
  • MIB profiles for device-specific SNMP metrics (including host/CPU/disk style rules)
  • Email and Telegram alert profiles, plus monitoring schedule windows
  • Public status page for selected monitors
  • Prometheus /metrics endpoint with dedicated API tokens (pm_…)
  • Ready-to-import Grafana dashboard for mini_noc_* metrics
  • REST API tokens for automation (monitors, series, dashboard, export)
  • System tools: Ping, Traceroute, and SNMP Walk
  • HTTPS certificate management, users with optional OTP, settings, license, and audit logs

How the suite works together

Use one product, or run all three as a compact operations stack.

  1. Authenticate VPN Auth decides who may connect and records the attempt.
  2. Control usage Quota Manager shows consumption and enforces bandwidth or access policy.
  3. Watch the network network monitor tracks hosts, services, and SNMP metrics with alerts.

Who it is for

  • Campus, branch, and data-center network teams
  • Security and VPN administrators who need shared identity
  • Operators who want deployable tools they can host themselves

Each mini-noc product ships with a web console, role-friendly administration, and logs you can use for day-to-day operations and audits.
