THE ATLAS TAKE
Rapid7 MDR combines a managed security operation with a detection and investigation platform and supported telemetry. Its Active Response documentation makes an important distinction: direct containment is an optional configuration, with supported endpoint and identity actions and explicit exclusions. Atlas analysis: it fits a team that wants a managed operation around Rapid7 and supported existing controls, provided the deployment establishes actual response authority. Evaluate the chosen service tier and current agreement rather than interpreting optional as necessarily a paid add-on. Verify the action path, excluded assets, and customer recovery tasks.

SCOPE
The Elite scope of service frames a collaboration and excludes anything not listed. Telemetry onboarding, supported detections, response prerequisites, and customer responsibilities limit what the service can do.

WORTH A LOOK WHEN
Teams adopting managed detection and investigation with explicit Rapid7 or supported third-party containment integrations.

THINK TWICE WHEN
The customer assumes MDR purchase alone enables endpoint isolation and user disablement without opt-in, connections, and exclusions.

IMPLEMENTATION
1. Identify the selected service tier
Record included technology, signal sources, response eligibility, and contractual responsibilities.

2. Configure response paths
Set connections, permissions, exclusions, and emergency contacts using lab targets first.

3. Rehearse containment and return
Verify the provider action and customer remediation, release, and closure procedure.

OPERATING REALITY
Telemetry sources, agents, response integrations, excluded critical assets, and customer contacts require maintenance. Atlas analysis: containment is only the beginning of recovery. Define how IT validates a quarantined system, rotates credentials where needed, restores service, and informs the provider that the incident can be closed.

COMMERCIAL CONSIDERATIONS
Use the written current service agreement to resolve tier-specific Active Response inclusion and underlying technology entitlement.
- MDR tier and protected estate
- Underlying telemetry and response technology
- Optional or included response and adjacent services

EVALUATION PLAN / PROPOSED TESTS, NOT COMPLETED RESULTS
1. Prove an authorized quarantine
Acceptance evidence: Retain the investigation, response connection, target-side isolation, and resulting action record.
Owner: __________  Pass criterion: __________
Observed result: __________  Evidence location: __________

2. Verify a user action
Acceptance evidence: Use a lab identity and confirm the exact disablement result and remaining session implications.
Owner: __________  Pass criterion: __________
Observed result: __________  Evidence location: __________

3. Exercise a critical exception
Acceptance evidence: Show a protected lab server follows the agreed alternative escalation instead of automatic containment.
Owner: __________  Pass criterion: __________
Observed result: __________  Evidence location: __________

QUESTIONS FOR THE VENDOR
- Which event sources are standard in the signed scope versus Custom Monitoring add-ons?
- Which contain actions does Rapid7 perform, and which remain customer IT prerequisites?
- How does this service responsibility matrix differ from Rapid7 Automation playbooks the customer staffs?

EVIDENCE GAPS
- No independent response-speed or detection-efficacy measurement was performed.
- Current tier eligibility and commercial inclusion of Active Response require confirmation.
