Managed Detection and Response
What is MDR (Managed Detection and Response)?
MDR is a service, not a product: a provider's analysts run threat detection and response for you around the clock, combining detection technology with real people who investigate and act. Lavawall® plus ThreeShield gives lean IT teams and MSPs that coverage without hiring a security department.

Definition
MDR answers a problem most organizations run into once they buy good detection tools: someone has to watch them at 2 a.m. The category, named by Gartner around 2016, describes a service where a provider's security analysts operate detection and response on your behalf, every hour of every day, using their own technology and expertise.
The point of MDR is the outcome, not the dashboard. Instead of handing you more alerts, the provider investigates what the tools surface, hunts for what the tools miss, and either contains the threat directly or tells you exactly what to do. You are buying handled incidents and answered questions, not another console to staff.
MDR overlaps with the older MSSP model and with plain EDR or XDR products, but its defining features are the round-the-clock human analysis, active threat hunting, and a real response, rather than tool management and forwarded notifications.
Core components
- A staffed SOC. Security analysts available around the clock, the part a lean IT team or a growing MSP cannot easily build in-house.
- Detection technology. The EDR, XDR, identity, and log sources that generate the signals the analysts work from.
- Threat hunting. Proactive searches through the telemetry for intrusions that never tripped an automated rule.
- Response. Containment actions taken for you, or clear, guided steps handed to your team, so an incident actually gets stopped.
- Reporting and review. Documentation of what happened and what was done, which feeds insurance, audit, and client conversations.
Why it matters
Attacks do not keep business hours, and the gap between a first foothold and real damage is often measured in hours. A lean IT team or a small MSP cannot realistically staff a 24/7 watch, so without a managed layer the overnight alert waits until morning. MDR closes that gap with people who are already awake and already know what normal looks like.
It also cuts through alert fatigue. Good tools produce a flood of signals, most of them noise; someone has to separate the one that matters. And like endpoint detection, a managed response capability increasingly shows up on cyber-insurance applications and in CMMC 2.0 and NIST CSF assessments, so having it, with evidence, helps you get covered and pass the audit.
How Lavawall® helps with MDR
Lavawall® splits the job the way MDR does, into technology and people. The platform is the multi-tenant detection layer: Microsoft 365 and Google Workspace identity monitoring, endpoint and network detection, Akira ransomware indicator hunting, and configuration-drift alerts, all correlated per tenant so a real incident stands out from the noise. Behind it, ThreeShield's CISSP/CISA team is the human escalation, the Tier 3 expertise you reach when something needs judgment, without hiring a security department of your own.
If you already run a dedicated MDR such as Huntress or Blackpoint, Lavawall® does not fight it. Those services integrate, and their incidents surface alongside Lavawall's own detections in one console, so an MSP watching dozens of tenants works from a single prioritized feed instead of five separate portals.
Frequently asked
- Is MDR the same as an MSSP?
- Not quite. A traditional MSSP mostly manages your security tools and forwards alerts. MDR is outcome-focused: the provider's analysts investigate, hunt, and either take or guide the response, so you get handled incidents rather than a queue to triage yourself.
- Is MDR the same as EDR or XDR?
- No. EDR and XDR are technologies, the sensors and correlation that produce detections. MDR is the human service that operates them around the clock on your behalf, often on top of an EDR or XDR platform.
- Does Lavawall® provide MDR?
- Lavawall® is the multi-tenant detection platform, and ThreeShield's CISSP/CISA team is the human escalation behind it, so you get MDR-style coverage without standing up your own SOC. An existing MDR such as Huntress or Blackpoint integrates and surfaces in the same console.
