Network monitoring that catches the outage before your CFO's Slack does
24/7 US-based NOC. NetFlow, SNMP, syslog, deep packet inspection, and synthetic checks correlated in one console, so you find the failing switch before the helpdesk floods.
Read-only collector install. First baseline in 48 hours. One-page health report on day 7.
24/7 across client estates
this quarter

contractual, with credits
Three lanes for network monitoring. Per-device pricing. The CFO sees the whole bill on one line.
All tiers run on the same NOC and the same runbook library. The difference is whether you need 24/7 coverage, deep packet inspection, ISP escalation, and multi-site work like SD-WAN and IoT segmentation.

Which signal catches which failure. Because "we monitor the network" doesn't mean anything.
A network can fail in seven different ways and a single tool catches maybe three of them. Here is what each layer in our stack catches, and where a single-vendor box falls short.
| Failure | What it looks like | Detection layer | What gets paged |
|---|---|---|---|
| Switch port flapping | Port goes up/down repeatedly, MAC table churn, spanning-tree recompute | SNMP traps + syslog correlation | P2 alert with port, MAC, last-known good time, and interface counter delta |
| Circuit brownout | ISP link still "up" but latency 4x normal, packet loss above 1.5% | NetFlow + ThousandEyes path analysis | P1 with ISP path map, hop-by-hop loss, ready-to-paste ticket for the carrier |
| Wi-Fi controller crash | APs orphan, clients reauth in waves, mDNS storm hits the wired side | Controller API polling + AP heartbeat | P1 with last AP-online timestamp, current orphan count, and rollback plan |
| BGP / OSPF route change | Default route flips, prefix withdrawal, AS path lengthens unexpectedly | Route-change watcher (BGPMon-style) | P1 with route diff, neighbor state, and a 10-minute history of advertisements |
| DNS resolver failure | Internal AD DNS slow or returning SERVFAIL, half the apps look "down" | Synthetic DNS checks (4 regions) + resolver query logs | P1 with which resolver, which zone, and the timing histogram |
| VPN tunnel drop | Site-to-site IPsec re-keys fail, branch offline to HQ but internet still works | Firewall API polling + tunnel keepalive | P1 with peer IP, last successful Phase 1, and pre-approved tunnel-restart runbook |
| Capacity exhaustion | Link saturated at 92% for 15 minutes, app latency climbs, retransmits spike | NetFlow top-talker + DPI app classification | P2 with the top 5 talkers by app, source, and dest, plus a one-click QoS proposal |
The full failure-coverage matrix (40+ failure modes mapped to detection layer and runbook) is in every proposal. Ask for the sample packet.
One Friday evening. One ISP brownout. NOC caught it 19 minutes before a single user noticed.
A 200-person architecture firm in Atlanta nearly lost their Friday-evening render queue to a Comcast Business brownout that the carrier was not yet seeing. This is how the NetFlow path data caught it. Names changed, timing and tools real.
"Glasswing Architecture" · 200 seats · Atlanta, GA
- 18:42:11 NetFlow collector flags retransmit ratio 0.08 → 1.9% on the primary cmcst-bus-1g circuit. ThousandEyes shows packet loss appearing at hop 3 (Comcast core, Atlanta).
- 18:42:34 Synthetic checks from our Dallas and Ashburn nodes confirm: external sites OK from elsewhere, packet loss only on paths transiting the Atlanta Comcast hop. This is upstream, not local.
- 18:43:07 Daniel Reyes (Phoenix NOC) picks up the page. Pulls last 60 minutes of show interfaces counters from the edge router, confirms input errors climbing on the Comcast handoff.
- 18:44:50 Pre-approved failover runbook fires: BGP local-pref shifted to send all egress through the secondary spectrum-bus-500m circuit. Inbound still uses Comcast for 90 seconds while the BGP withdrawal propagates.
- 18:46:22 Failover complete. NetFlow on the secondary now showing the render queue + Revit Cloud Worksharing flowing clean. Loss back to 0.04%. Zero user-visible interruption (TCP retransmits absorbed it).
- 18:47:08 Daniel calls Comcast Business with the CID, the path-trace evidence pack, and the Glasswing letter of authorization on file. Carrier ticket opened. Comcast acknowledges the Atlanta core issue at 18:51, opens internal P1 at 18:58.
- 19:01:00 Stable on backup. 19 minutes from first NetFlow signal to a working failover. The first user message into IT arrived at 19:00:48 asking why a render seemed slow, and the engineer was able to reply "fixed, ignore."
- Saturday 11:18 Comcast resolves the upstream peering issue at 11:14 Saturday. Daniel's relief shifts BGP local-pref back to primary at 11:18 during a quiet window. 17 hours of clean operation on the secondary. Carrier credit eligibility documented and filed for the client.
Auditors don't want a screenshot of a dashboard. They want a quarter of correlated logs.
Network monitoring data is half of what your auditor asks for during a SOC 2 or HIPAA review. Every quarter we ship the evidence packet with the right log samples, the right retention attestations, and the right control mappings. Your assessor finishes in days, not weeks.
When the link goes red at 2 AM, these are the people on the bridge.
Our NOC is staffed in-house across Tampa, Orlando, Chicago, and Phoenix. No overseas tier-1 wall. Every engineer holds at least one current network certification and has carrier-side experience before they take a shift.
Five questions. Honest answers.
Will you replace our existing monitoring tools?
Usually no. If you already run Auvik, LogicMonitor, PRTG, or the Meraki Dashboard, we keep them and put a NOC behind them. We add NetFlow collectors, syslog ingest, and synthetic checks where there are gaps. The win is the people, the runbooks, and the correlation, not a forklift of your tools.
We will recommend a replacement when something is genuinely end-of-life (Orion 2018, anyone?) or when the licensing math no longer makes sense versus a consolidated stack. That's a conversation, not a default.
What's the difference between NOC monitoring and an MSP?
An MSP owns the helpdesk and the user experience. A NOC owns the network plane. We watch switches, routers, firewalls, ISP links, Wi-Fi controllers, and synthetic transactions. When we see a circuit brown out, we call your ISP, open the ticket, sit on hold, and feed your MSP the root-cause data so they can update users.
About two-thirds of our NOC clients also run an MSP. About a third use us as their only network team because they don't have one. Either way works, the runbooks are the same.
How fast do you actually respond to a P1?
Median P1 acknowledgement is 4 minutes 12 seconds. We commit to under 15 minutes contractually with credits if we miss. P1 means a site is hard down, a core circuit has dropped, or a synthetic transaction is failing for the whole user base. P2 (degradation) is 30 minutes. P3 (single user, capacity warnings, scheduled work) is next business day.
We page out of PagerDuty to a US-based on-call engineer who already has your runbooks open in another tab. No tier-1 reading from a script.
Do you handle the ISP / carrier escalation for us?
Yes, on the 24/7 and Enterprise tiers. We hold your CIDs, account numbers, and authorized-contact letter on file. When AT&T, Spectrum, Comcast Business, Lumen, or Verizon needs to be called at 2am, we call them. We open the ticket, escalate when the front line stalls, demand the smart-hands dispatch, and stay on the bridge until the link is back.
You get the after-action with the carrier ticket number, the path-trace evidence we sent, and the credit-eligibility note for your AP team to claim.
What if we already have an internal NOC?
Then we run an overnight and weekend tier behind your team. About 20% of our NOC clients have a daytime team and use us for follow-the-sun coverage from 6pm Friday to 6am Monday. We use your tools, follow your runbooks, and hand the bridge back at shift change with a written log.
We can also act as the L3 escalation behind a smaller internal NOC for routing, BGP, SD-WAN, and DPI work the day shift may not have the bench depth to handle.
Find the bottleneck before your users do.
Our free 30-day NOC trial deploys a read-only collector, baselines your network in 48 hours, and runs the NOC for the full 30 days. You'll get a 1-page health report on day 7 with the top 10 noisiest devices, the worst-performing circuits, and the capacity ceilings you're closest to hitting. No credit card. Keep the report either way.
