The problem

Service provided is not service consumed

A single Teams call depends on five or more parties. Most monitoring watches only the end it owns.

  1. User
  2. Wi-Fi
  3. Office LAN
  4. WAN / ISP
  5. ZTNA / VPN
  6. Identity
  7. App / SaaS

Provider-side monitoring: servers, SLAs, status pages.

What your users experience, end to end. This is what CNA measures.

Slow root cause

Each team proves its own innocence first, while users wait.

Alert fatigue

Per-component alerts fire constantly and say little about users.

No end-to-end owner

Wi-Fi, ISP, security cloud and SaaS each see only their own slice.

How it works

Four vantage points, one portal

We measure the same service from every angle, so the answer is usually obvious. You don't have to change anything in your network.

Office sensor

Apps, DNS, Wi-Fi and the network path, 24/7, from where your people sit.

Digital experience

Server and VM agent

Linux and Windows servers behind the service, on the same timeline.

Infrastructure

End-user device agent

The same view from the user's own Windows laptop.

Laptop agent

Cloud WAN probes

Your circuits tested from the cloud at every site, with availability.

WAN circuits

Outbound only, to a Cloud Unit dedicated to you. Change an app, a threshold or a Wi-Fi profile in the portal and every sensor follows within a poll cycle. Alert rules regenerate automatically. See the architecture.

Outcomes

Finding the fault in minutes, not meetings

By the time someone opens the dashboard, the question has moved on from "is there a problem" to "who fixes it".

≈10–15 min For a sustained problem to raise an alert, day or night, often before the first call. Estimated from the default alert settings; tunable for you.

One site or every site?

One site slow and the rest fine: it's local. Every site slow: the provider or the SaaS. Sensors fine but laptops slow: the device.

One app or all of them?

Tells you whether to look at the application or the network.

Which hop?

Inside the office, at the ISP or at the SaaS edge. You hand the provider evidence, not a complaint.

Is it the Wi-Fi?

Coverage, interference or roaming, with the access-point details your wireless provider needs.

What changes for you

Fewer escalations, faster answers, better evidence

Service management

Real-time visibility from the user's side, plus the history to set a baseline.

Service improvement

Catch weaknesses before they become incidents. Measure a Wi-Fi refresh or an SD-WAN or ZTNA rollout before and after.

Operational efficiency

Faster fault identification, fewer escalations bouncing between teams, and provider tickets backed by evidence.

AI-powered portal

Ask the portal what's going on

When an alert fires at 7am, the first person to see it often isn't a network engineer. The built-in AI assistant answers in plain English, from your own data, and suggests what to check next.

  • Included as standard for up to 3 users
  • Dashboards, floor maps and alerts in one place
  • A private AI option is coming next

Explore the portal

The AI assistant answering 'can you explain what the data reported on this dashboard mean?' with a plain-English explanation of Wi-Fi signal strength and reception quality.

Security

Secure by design, independently assured

Sensor

No inbound access, physical ports disabled, storage that unlocks only on the network.

Transport

Outbound only: data over TLS, and management sessions started by the device.

Portal

Single sign-on with your identity provider, role-based views, source-IP or VPN restriction.

Isolation

A dedicated Cloud Unit per client, with its own portal and databases.
