Managed Detection and Response (MDR)

We operate the platform we build for you — triage, hunting and containment by people who know your baseline, without you standing up a 24/7 SOC.

Home Services Managed detection & response

  • MDR
  • XDR
  • 24/7 triage
  • You own the platform

In plain terms

We watch your security alerts for you, around the clock, and act on the real ones. The difference from most providers is that you own the software and the data — if you ever take the work in-house or move to someone else, everything stays with you.

Most managed detection and response providers put your estate behind their stack and their process. We do the opposite: we build the platform, you own it and the data, and we operate it as an extension of your team.

How the service works

Managed detection and response operating modelTelemetry from the customer estate flows to the CerbaCore team for triage, hunting and escalation, with containment actions returned to the estate and findings fed back as tuning.YOUR ESTATEEndpointsunified EPP + EDR agentNetwork + OTsegmentation, NACCloud + identitytelemetryCERBACORE MDRTriagetuned to your baselineThreat huntinghypothesis-drivenEscalation + reportingactionContainisolateblockroll backdetections become tuning and new detection content
You keep ownership of the platform and the data. We operate it — and every detection improves the tuning rather than resetting it.

Telemetry from endpoints, network, OT and identity flows to our analysts. We triage against a baseline we established during deployment — not a generic one — hunt on hypotheses drawn from your sector's actual threat profile, and contain through the same automation described in zero-trust segmentation.

What separates this from a typical MDR contract

Conventional MDR

  • Their platform, their license, their data lake
  • Leaving means losing your detection history
  • Tuning is generic across their whole book
  • Containment stops at the endpoint
  • You see alerts, not reasoning

CerbaCore MDR

  • Your platform, your license, your telemetry
  • You keep everything if you take it in-house
  • Tuned to your environment during deployment
  • Containment reaches the router and the VLAN
  • Detection logic is documented and yours to read

Service tiers

  • Co-managed. You keep the console and the first-line response; we take after-hours, escalation and detection engineering.
  • Fully managed. We own triage and containment end to end, with defined authority for automated actions and an agreed escalation matrix.
  • Managed extended detection and response. Endpoint plus network, OT, cloud and identity correlated in one timeline rather than four consoles.

What you get every month

  • Detections raised, contained and closed, with dwell time per incident
  • New detection content written for your environment that month
  • Tuning changes and what drove them
  • Coverage gaps we found and what it would take to close them

The last line is the one most reports omit. If a part of your estate is not producing usable telemetry, you should hear it from us before you hear it from an incident.

Triage and escalation

MDR triage and escalation flowDetections are auto-contained where confidence is high, otherwise triaged by Tier 1, with true positives escalated to Tier 2 and false positives closed by tuning the rule.AutomationTier 1Tier 2 / IRDetectionAuto-contain?high confidenceyesContainedNotifynoAnalyst triageTrue positive?noClose + tune the ruleyesInvestigateContain + eradicateReport + new contentevery false positive closes a rule gap — if the same alert is triaged twice, the tuning step was skipped
The tuning branch is the one that compounds. Skip it and volume grows forever.

Critical containment is automated because five minutes of human acknowledgement is already too slow for ransomware. The analyst's job on a critical is to verify and extend containment, not to initiate it.

What "tuned to your baseline" means

Generic tuning is why most MDR relationships settle into mutual frustration. A backup agent reading every file looks identical to staged exfiltration unless the platform knows it is your backup agent.

Your legitimate behaviorGeneric verdictAfter baselining
Backup agent bulk file read, 02:00Possible exfiltrationKnown, suppressed; alerts only off-schedule
Developers compiling and running unsigned binariesSuspicious executionScoped to dev subnet and dev identities only
Quarter-end batch touching every finance hostLateral movementKnown calendar window; outside it, still alerts
Vendor remote session into plant HMIUnknown remote accessAllowed from named source, time-boxed, recorded

Every suppression is scoped and expires. An unscoped permanent suppression is a hole, and they accumulate silently.

How to compare MDR service providers

Most managed detection and response vendors present similar capability slides. These are the questions that actually separate MDR service providers in practice:

QuestionWhy it matters
Who owns the platform and the telemetry?If they do, leaving costs you your detection history
Is tuning specific to us or shared across your book?Generic tuning is the root of most alert fatigue
What can you contain without calling us?Undefined authority means nothing happens at 03:00
Does containment reach the network?Endpoint-only containment leaves lateral movement open
How many alerts will need a human each week?The only volume number that describes your workload
Can we read the detection logic?Opaque rules cannot be defended to an assessor

How 24/7 coverage is actually staffed

Follow-the-sun coverage modelThree eight-hour windows — APAC, EMEA then AMER — each handing over to the next so that monitoring is continuous while every analyst works daytime hours.24/7 coverage without a night shift — every analyst works daylight hoursAPAC00:00–08:00 UTCSingapore / Sydney hourshandoverEMEA08:00–16:00 UTCLondon / Dubai hourshandoverAMER16:00–24:00 UTCUS Eastern / Pacific hourshandover is a written brief on every open investigation, not a shared inboxAlert fatigue and missed detections concentrate in overnight shifts. Following the sun removes the shift rather than staffing it.
The reason this matters is quality, not just coverage: detections missed at 03:00 are a staffing artifact, and this removes the 03:00 shift entirely.

Serving AMER, EMEA and APAC is what makes this possible. Three eight-hour windows, each covered by analysts working their own daylight hours, with a written handover brief on every open investigation at each boundary. The alternative — one region staffing a night shift — produces measurably worse triage at exactly the hours intrusions are timed for.

Window (UTC)PrimaryCovers business hours in
00:00–08:00APACAustralia, New Zealand, Japan, Singapore, India
08:00–16:00EMEAUK, Europe, Middle East, Africa
16:00–24:00AMERNorth America, Latin America

Handover is a structured brief, not a shared inbox: every open investigation carries current hypothesis, actions taken, actions deliberately not taken, and the next step. Investigations dropped at a shift boundary are the most common quality failure in 24/7 operations.

Worked example — 900-seat healthcare provider, first 90 days

  1. Days 1–14, deploy and observeAgents to 900 endpoints, clinical devices monitored at the network layer only. Everything in detect-only. 4,100 alerts in week one, which is normal and means nothing yet.
  2. Days 15–45, baseline and tuneAlert volume from 4,100/week to 130/week. The reduction is almost entirely legitimate clinical software doing things that look alarming out of context — imaging systems bulk-reading studies, an ancient pharmacy application that injects into its own process.
  3. Day 31, first real detectionCredential theft from a workstation in radiology, caught by behavioral scoring during detect-only. Contained manually within 20 minutes, because automation was not yet armed. This is the trade during the tuning window and we say so up front.
  4. Days 46–60, arm automationAuto-containment enabled for corporate endpoints, business hours, high-confidence only. All clinical devices registered never-isolate.
  5. Days 61–90, extendAutomation to 24/7 after the release path was exercised twice on real detections. Alert volume steady at 90–120/week with 4–8 requiring human investigation.

The number that matters

Not alerts raised — alerts requiring a human. Four to eight per week is a load a small team can actually sustain. A service reporting thousands of "threats blocked" monthly is reporting its marketing funnel, not your risk.

Common questions

What is managed detection and response?

Managed detection and response (MDR) is an outsourced service combining detection technology with human analysts who triage, investigate and contain threats on your behalf, typically around the clock. It differs from a traditional managed security service in that the provider takes response actions rather than only forwarding alerts.

How is MDR different from EDR and XDR?

EDR and XDR are products; MDR is a service. EDR covers endpoints, XDR correlates endpoint with network, cloud and identity, and MDR is people operating either of them for you. You can buy XDR and run it yourself, or buy MDR and have it run for you.
