TK Comms SentinelTK Comms Sentinel

Network & comms infrastructure monitoring, live

The team already knows what's about to fail — before the users report it.

TK COMMS SENTINEL gives every switch, port, and link on your network a live status — with enough history to know if "slow" is new, and enough precision to name the exact port. Built and proven against a real hospital network — about as unforgiving an environment as it gets.

Why this matters

Critical infrastructure networks are not ordinary IT

In a network that isn't allowed to go down — a hospital, a financial institution, an industrial site — dozens of switches and hundreds of ports carry equipment that can't drop for a moment. A single failing port doesn't always announce itself clearly: sometimes it just slows down, stutters, or drops one device while the network around it looks perfectly healthy.

General-purpose IT monitoring tools are built for a uniform office network, not for the physical layout of dozens of departments with multi-vendor equipment added over the years. TK COMMS SENTINEL was built and proven against a real hospital network — and now fits any enterprise network with the same reliability bar.

  • Port overload — caught and reported before the slowdown is felt at the clinical workstation.
  • A switch going down — immediate alert, distinguishing a single device fault from a wider path outage.
  • Unidentified equipment — located by IP or MAC, down to the exact switch and physical port.

What the system actually does

Three groups of capability

Visibility, diagnosis, and resilience — each answering a different stage in the life of a network fault.

VIS — Visibility
VIS-01

Multi-vendor SNMP monitoring

Aruba, HPE Comware, Check Point, and other L2/L3 switches — polled in parallel, no agent required on any device.

VIS-02

Real-time dashboard

Bandwidth load, device availability, active faults, and the worst-performing ports over the last 24 hours — at a glance.

VIS-03

Automatic LLDP topology

Uplink connections between switches are detected automatically, so the system — and you — never mistake an end device for infrastructure.

DIA — Diagnosis
DIA-01

Per-port traffic history

A 48-hour graph for every interface individually — throughput and errors — for investigating a fault after it already happened.

DIA-02

Find by IP or MAC

Enter an address — the system locates which switch and which physical port the device is actually connected to, even when the lookup crosses L3 routing.

DIA-03

Targeted email alerts

A direct link to the specific device and port in the alert — not "something's wrong somewhere on the network," but exactly where.

SEC — Resilience & security
SEC-01

Enterprise-grade sign-in

Active Directory over LDAPS, mandatory two-factor authentication, and a separate local emergency account for outages.

SEC-02

Runs fully offline

Suited to an air-gapped network. No dependency on any external cloud service for day-to-day operation.

SEC-03

Complete audit log

Every permission change, login, and alert-threshold change is recorded permanently and documented.

How it works

From polling cycle to inbox alert

STAGE 01

Continuous polling

Every device is checked on a set cycle — anywhere from 30 seconds to a few minutes — over SNMP, no local agent needed.

STAGE 02

Anomaly detection

Load, port errors, or disconnects are compared against configured thresholds — per device, per single port, or network-wide.

STAGE 03

Alert & action

An email with a direct link to the problem port goes out to the team — before the fault is felt at the clinical workstation.

A view from the system (illustrative)

The same dashboard the team sees every morning

The example below uses fictional names and figures — not a real network — purely to illustrate the kind of view this is.
