Managed Detection and Response Services for 24/7 Threat Monitoring
HTG’s managed detection and response services connect supported security telemetry to analyst investigation, defined escalation, and agreed response actions. The scope states what is monitored, who is contacted, which actions are authorized, and where responsibility sits between your team, HTG, and the selected security platform or SOC partner.
Define the Telemetry, Escalation and Authority.Before the Incident Defines It for You.
The MDR Operating Model
Monitoring Is Only UsefulWhen the Handoff Is Defined.
Buying an MDR platform does not settle who watches which signals, who decides an alert is credible, who calls at 2:00 a.m., or who may isolate a device. HTG defines those responsibilities before service begins.
Visibility Without Assumptions
Confirm which endpoint, identity, cloud, email, server, SaaS, and network sources are actually connected, supported, and reporting usable telemetry.
Escalation That Works After Hours
Set severity thresholds, primary and backup contacts, notification expectations, and the process to follow when the first responder does not answer.
Authority Before the Incident
Document which containment actions are pre-approved, which require client authorization, and who owns remediation and recovery after the immediate threat is contained.
Managed Detection and Response Services Scope
SOC Monitoring, XDR Servicesand Managed Threat Response.
The approved model may combine endpoint detection, XDR services, SIEM or log monitoring, SOC review, threat hunting, and managed threat response across supported data sources. Exact capabilities depend on the connected telemetry, selected platform, service tier, and response authority.
Visibility & Investigation
Supported Telemetry and Analyst Alert Review
Analysts review approved signals, add context, separate credible threats from routine activity, and assign urgency based on the evidence available.
- Connected data sources confirmed during onboarding
- Coverage gaps and reporting failures documented
- Enrichment, false-positive reduction, and tier-specific threat hunting
- Priority and affected-asset context
Escalation & Action
Defined Communication and Approved Containment
Contact paths and response boundaries are set before an event, including which supported actions may be taken immediately and which require approval.
- Severity-based notification and backup contacts
- Pre-approved versus approval-required actions
- Endpoint isolation or account action when supported
- Evidence-preservation considerations
Remediation & Improvement
Cleanup, Recovery, Reporting, and Tuning
Containment is only the first step. HTG helps route the technical work, validate return to service, and review what should change after the event.
- Credential resets, patching, rebuilds, and recovery
- Internal IT, vendor, and platform coordination
- Operational reporting and detection tuning
- Follow-up actions with named ownership
Responsibilities and Boundaries
A Working MDR Scope NamesWho Owns What During an Event.
Responsibilities vary by platform, service tier, and authorization. The statement of work should define the handoff rather than imply every response action is automatically included.
HTG and the Selected MDR or SOC Service
HTG defines the client operating model, coordinates the selected security platform or SOC partner, and manages the technical handoffs assigned in the agreement. The underlying provider performs only the monitoring, investigation, hunting, and response functions included in its service tier.
- Confirm supported sources, connection health, and coverage gaps
- Review and prioritize alerts within the selected model
- Recommend or perform supported actions when authorized
- Coordinate technical remediation and recovery when included
- Document findings, escalation, and the service response
Business Context, Decisions, and External Obligations
The client retains responsibilities that require internal authority, business judgment, or separately engaged legal, insurance, regulatory, and communications support.
- Provide access, system context, and environment changes
- Approve actions outside standing authority
- Manage application and business-process decisions
- Own legal, regulatory, employee, and customer communications
- Maintain current contacts and escalation availability
Coverage is platform-dependent and confirmed in the statement of work. HTG may deliver the client-facing service through approved security platforms and SOC partners while remaining responsible for solution design, implementation, administration, escalation coordination, remediation handoffs, and ongoing account management within the agreed scope.
Define Coverage Before the First Alert
MDR Onboarding Should Testthe Handoff, Not Just the Connection.
The service is ready only when telemetry is validated, escalation contacts are current, response authority is clear, and the team has walked through a realistic event. Current NIST incident-response guidance treats detection, response, recovery, and third-party coordination as one operating process. Review NIST SP 800-61 Rev. 3.
Map the Environment
Confirm endpoints, identities, cloud services, critical systems, current tools, and the places where visibility is limited.
Connect and Validate
Onboard supported telemetry, verify reporting, and document exclusions, retention limits, and technical dependencies.
Set Escalation Rules
Agree on severity, contacts, after-hours expectations, and actions that may be taken without waiting for approval.
Test the Handoff
Walk through a realistic event from investigation through containment, recovery, communication, and post-event review.
From Signal to Decision
Six HandoffsEvery MDR ScopeShould Name
These are the points where otherwise capable services break down. HTG puts the collection, investigation, escalation, action, recovery, and review path in writing during design and onboarding.
Fit and Different Starting Points
When MDR Services Are the Right Next Step
MDR is a strong fit when alerts wait until business hours, endpoint and identity signals live in separate tools, nobody owns first investigation, response authority is unclear, or leadership needs evidence that alerts are consistently reviewed.
When continuous monitoring is not the main issue, start with a broader risk review, compliance readiness, or managed IT operations instead of forcing the need into an MDR scope.
Managed Detection and Response FAQs
Questions to SettleBefore Signing an MDR Agreement.
The agreement should clearly state what is monitored, what the service can do, who must respond, and what no MDR provider can guarantee.
Technology and Coverage
Is MDR the same as antivirus or EDR?
No. Antivirus and EDR are technologies that detect or block activity on endpoints. Managed detection and response adds people and operating procedures around supported telemetry: investigation, prioritization, escalation, and agreed response. The exact data sources and actions depend on the selected model.
Does MDR monitor every system and log source?
Not automatically. Coverage depends on connected sources, licensing, platform support, configuration, and retention. HTG confirms what is in scope and identifies visibility gaps during design and onboarding.
Can an analyst isolate a device or disable an account?
Possibly, when the platform supports the action and the statement of work grants authority. Some actions may be pre-approved; others may require a client decision because they can interrupt business operations.
Response and Outcomes
What happens after an alert is escalated?
The agreed response path begins. That may include client notification, containment, credential action, remediation coordination, recovery work, and a post-event review. The parties responsible for each step should be named before service starts.
Does MDR guarantee that a breach will not occur?
No. MDR can improve visibility and response, but no provider can guarantee prevention or a specific outcome. Results depend on available telemetry, configuration, response authority, client participation, and the nature of the attack.
Can HTG work with our internal IT or security team?
Yes. Many MDR engagements are co-managed. HTG can coordinate the monitoring service, handle defined technical work, and escalate decisions to internal IT or security. The agreement should name who owns endpoint, identity, cloud, network, application, recovery, legal, and communication actions.
How quickly can MDR service begin?
Timing depends on platform selection, licensing, endpoint count, data-source access, deployment method, change control, and the condition of the current environment. HTG first confirms the operating model, then validates telemetry and escalation before treating the service as live.
Before the Next Security Incident
Define the Monitoringand Escalation Model.Before an Alert Becomes an Argument.
Bring your current endpoint, identity, cloud, email, network, SIEM, and security tools to the conversation. HTG will map the telemetry, coverage boundaries, contacts, response authority, and remediation handoffs, then identify whether the current model needs correction, expansion, or replacement.
