Most engineers think…
Most people assume that to monitor a network you must deploy a fleet of probes, NetFlow collectors and per-app agents, then stitch their data together in yet another tool. With Cato, that mental model is simply wrong.
Because every session transits Cato's PoPs, the platform already sees the whole path end-to-end — so observability is native, a by-product of forwarding traffic, not a bolt-on. The Cato Management Application turns that into one console of real-time and historical dashboards, and Digital Experience Monitoring (DEM) splits any session into the last mile, the Cato backbone and the application so you can prove which segment is slow. That is what lets you stop guessing — and stop blaming the network by reflex.
① Native observability — Cato already sees the whole path
The single most important idea: in Cato, observability is native. Because all traffic transits Cato's PoPs — user-to-site, site-to-site and user-or-site-to-cloud — Cato already has end-to-end telemetry for every session. There are no extra probes, no NetFlow collectors and no per-app agents to deploy. The monitoring data is generated simply because Cato forwards the traffic.
That telemetry surfaces in the Cato Management Application (CMA) — one cloud console with real-time and historical dashboards. From here you read traffic analytics, the top applications, sites and users, bandwidth and throughput trends, and a full security events timeline. One pane covers the whole estate, not a different tool per site.
In an interview, do not stop at 'Cato has great visibility'. Explain the mechanism: because every session transits Cato's PoPs, the platform already sees the whole path, so observability is a by-product of forwarding traffic — no probes, collectors or per-app agents. That 'because' is what earns the marks.
Why is observability described as 'native' in Cato?
② The real problem — 'the app is slow and everyone blames the network'
Every IT team knows this fight. A cloud app feels slow, the complaints land on the network team, and — with no evidence to the contrary — the network gets blamed by default. The team then spends hours reconfiguring links, swapping cables and rebooting kit while the real fault sits somewhere they can't see.
The reason this happens is a visibility gap. A user's session crosses several owners: their local ISP (the last mile), the transport in the middle, and the SaaS provider's own service. Without per-segment evidence, you can't tell whose fault it is — so the loudest assumption wins, and that is usually 'it's the network'. Cato closes that gap with Digital Experience Monitoring, which we meet next.
Visibility that comes for free because all traffic transits Cato's PoPs — no extra probes, collectors or per-app agents to deploy.
One cloud console with real-time and historical dashboards: traffic analytics, top apps, sites and users, bandwidth and a security events timeline.
Splits a session into last mile, Cato backbone and application, with real-user + synthetic metrics and hop-by-hop latency and loss.
Correlates raw events into a prioritised list (Stories) and lets analysts pivot through them (Workbench) instead of drowning in noise.
Why does the network get blamed by default when a cloud app feels slow?
③ Digital Experience Monitoring — last mile vs backbone vs application
Digital Experience Monitoring (DEM) gives end-to-end visibility into the user experience by splitting every session into three segments: the last mile (the user's or site's local ISP link), the Cato backbone (transport across the PoPs), and the application / SaaS (the provider's own response time). For each segment DEM shows latency and loss, hop-by-hop.
How it measures
DEM combines real-user metrics (drawn from actual user traffic) with synthetic monitoring (scheduled test transactions that probe an app even when nobody is using it). Put together, you get one objective picture that answers the only question that matters during an outage: is it the user's ISP, the Cato backbone, or the SaaS provider? The faulty segment lights up; the healthy ones stay green.
Classic network monitoring tells you a link is up or busy. DEM measures the user experience across three segments — last mile, Cato backbone and application — with real-user and synthetic metrics. Saying 'DEM is just ping/SNMP' misses the whole point: it localises the fault to a segment, including the SaaS app itself.
▶ Watch DEM pin a slow SaaS app on the right segment

DEM shows the last mile and Cato backbone healthy, but the application segment is slow. Where is the fault?
④ Using analytics & DEM — accountability, capacity and the pitfalls
DEM is not just for firefighting. Once you have per-segment evidence, you can hold the right party accountable: take a DEM report to your ISP when the last mile is the problem, or to the SaaS vendor when the application segment is. You stop reconfiguring a network that was never broken.
And use the analytics forward
The same telemetry feeds capacity planning (bandwidth trends and link sizing), application discovery (what is really running, including shadow IT), and security investigations — where Stories correlate raw events into a prioritised list and the Workbench lets analysts pivot through them. The pitfalls to avoid: blaming 'the network' without DEM evidence; not using DEM to push back on ISPs and SaaS providers; and ignoring the analytics for capacity and app-usage trends until something breaks.
Priya, an IT manager at a Kochi logistics firm, faces this
Sales staff complain the cloud CRM is 'unusably slow' every afternoon and the network team is being blamed; they have already rebooted the Cato Socket twice with no change.
The slowness sits in an external segment, not Cato — but nobody has per-segment evidence, so the network is the default scapegoat.
Open the CRM session in DEM: the last mile and the Cato backbone show healthy latency and near-zero loss, while the application segment (the SaaS CRM's own response time) spikes in the afternoon window.
Cato Management Application ▸ Monitoring ▸ Experience Monitoring (DEM)Stop reconfiguring the network. Take the DEM report to the SaaS CRM vendor as objective evidence that their service is the bottleneck and open a ticket with them; confirm in Analytics that bandwidth headroom is fine so no capacity change is needed.
Re-check the DEM timeline after the vendor's fix — the application segment drops back into the green while last mile and backbone stay healthy, and the afternoon complaints stop.
Never close a 'network is slow' ticket on a hunch. Open DEM, read latency and loss for each segment, and confirm which one is red. That single read often shows the network is healthy and the SaaS app is the problem — saving hours of pointless reconfiguration and giving you evidence to push back.

📖 Glossary
- Native observability
- Monitoring data produced as a by-product of forwarding traffic, because all traffic transits Cato's PoPs — no separate probes, collectors or per-app agents.
- Cato PoP (Point of Presence)
- A Cato data-centre location in the global private backbone that every session transits, which is why Cato sees the whole path.
- Cato Management Application (CMA)
- The single cloud console with real-time and historical dashboards for traffic, top apps/sites/users, bandwidth and security events.
- Digital Experience Monitoring (DEM)
- End-to-end user-experience monitoring that splits a session into last mile, Cato backbone and application, with latency and loss per segment.
- Last mile
- The local-access segment between the user or site and the Cato PoP — typically the local ISP link.
- Real-user vs synthetic monitoring
- Metrics from actual user traffic versus scheduled test transactions; DEM combines both for an objective view.
- Stories / Workbench
- Cato's correlation surface: Stories group raw events into a prioritised list and the Workbench lets analysts pivot through them.
- Application discovery
- Using the telemetry to see which applications are actually in use across the estate, including shadow IT.
