Definition
MDR developed as a response to the staffing reality of cybersecurity: most organisations cannot operate a 24/7 SOC themselves. Hiring, training, and retaining security analysts at scale is expensive; MDR providers spread that cost across many customers and offer 24/7 coverage as a service.
MDR is a service, not a technology. MDR providers may use their own technology (Huntress, Blackpoint, Arctic Wolf), the customer's technology, or a combination. The defining feature is the 24/7 human triage layer, not the underlying detection product.
For MSPs specifically, MDR providers in the channel (Huntress, Blackpoint, SentinelOne Vigilance, Sophos MDR) extend the MSP's capacity by handling the after-hours and high-complexity detection-and-response work that would otherwise require the MSP to staff its own SOC.
Core components
- 24/7 Security Operations Centre (SOC). Human analysts on duty around the clock.
- Detection technology. EDR, XDR, M365 ITDR, or similar detection products operated by the MDR provider.
- Incident triage and escalation. Analyst review of alerts; escalation to the customer with context and recommended actions.
- Response actions. Some MDRs perform response actions on the customer's behalf (host isolation, account disablement); others escalate for the customer to act.
- Threat hunting. Proactive hunting for indicators that would not generate automated alerts.
- Reporting. Periodic incident, threat-landscape, and posture reporting.
Why it matters
For organisations that cannot staff a 24/7 SOC themselves — most SMBs and many mid-market organisations — MDR is the practical way to get round-the-clock coverage.
For MSPs, MDR providers in the channel extend the MSP's capacity. The MSP retains the customer relationship and broader service delivery; the MDR provider delivers the 24/7 detection-and-response work.
Cyber-insurance assessments increasingly ask about 24/7 monitoring. MDR coverage is the most practical answer for SMBs.
How Lavawall® helps with MDR (Managed Detection and Response)
Lavawall® is the platform; Lavawall® itself is not a 24/7 managed SOC. For MSPs that want managed detection-and-response, Lavawall® integrates with major MDR providers (Huntress, Sophos MDR) so MDR incidents surface in the Lavawall® console alongside Lavawall®'s own findings.
ThreeShield Information Security Corporation, the audit firm that built Lavawall®, offers Tier 3 cybersecurity augmentation for MSPs and lean IT teams — CISSP- and CISA-credentialled human escalation that complements automated detection. ThreeShield engagements span DIY (self-service via Lavawall®), Supported (Tier 3 augmentation), and Done-for-you (full audit and managed compliance).
For MSPs that want managed detection alongside the broader Lavawall® platform, the Lavawall® + Huntress / Blackpoint + ThreeShield Tier 3 augmentation combination is a common pattern.
Frequently asked
- Is MDR the same as XDR?
- No. XDR is a technology category; MDR is a service category. “Managed XDR” is the combination of XDR technology with MDR service delivery.
- Does Lavawall® offer MDR?
- Lavawall® integrates with MDR providers; ThreeShield offers Tier 3 augmentation that overlaps with MDR for MSPs and lean IT teams. For 24/7 managed SOC, Huntress, Blackpoint, and similar partners are common pairings.
- What's the difference between MDR and a managed SIEM?
- Managed SIEM focuses on log aggregation and correlation. MDR includes detection technology, threat hunting, and incident response — a broader service.
