What does DESSS deliver for Defender for Endpoint

DESSS delivers Defender for Endpoint on Microsoft Defender & Sentinel through the defender for endpoint deployment: threat model and use cases; telemetry onboarding; detection engineering; triage runbooks and escalation; tuning window; operations and hunting. Each step closes with named deliverables you sign off before the next begins.

THE WORKFLOW

6 steps, start to finish

Every engagement follows a documented sequence, so you always know which stage the work is in and what closes it.

Threat model and use cases — Weeks 1–2
Telemetry onboarding — Weeks 2–5
Detection engineering — Weeks 4–7
Triage runbooks and escalation — Weeks 6–8
Tuning window — Weeks 8–11
Operations and hunting — Ongoing

WHAT YOU GET

Named deliverables, signed off

Each step closes with deliverables you review and approve before the next one begins — progress you can audit rather than a status colour on a slide.

HOW WE DELIVER

Inside the Defender for Endpoint workflow

Detection built from your threat model, tuned until analysts can sustain the alert volume.

Step 01

Weeks 1–2

Threat model and use cases

Detection use cases are selected from the threats that realistically apply to your sector and estate, so Defender for Endpoint collects telemetry for a purpose instead of filling storage.

Deliverables:

Use-case catalogue
Threat model
Priority detections

Step 04

Weeks 6–8

Triage runbooks and escalation

Severity definitions, triage procedures, escalation contacts and out-of-hours authority are documented and agreed, so the first real incident is not the first conversation about them.

Deliverables:

Triage runbooks
Escalation matrix
Severity definitions

Step 02

Weeks 2–5

Telemetry onboarding

Identity, endpoint, email, network and cloud sources are connected with parsing validated and ingestion tiered by value, because cost control is part of the design in Microsoft Defender & Sentinel.

Deliverables:

Connected sources
Parsing validation
Ingestion cost model

Step 05

Weeks 8–11

Tuning window

A deliberate tuning period drives false positives down to a level a human can sustain, with every suppression documented and reviewed rather than quietly applied.

Deliverables:

Tuning log
False positive trend
Suppression register

Step 03

Weeks 4–7

Detection engineering

Analytics rules are mapped to MITRE ATT&CK techniques, written against your environment, and tested with simulated activity before they are trusted.

Deliverables:

Analytics rules
ATT&CK coverage map
Simulation results

Step 06

Ongoing

Operations and hunting

Monthly reporting on incidents, response times and coverage gaps is paired with quarterly threat hunting that feeds new detections back into Defender for Endpoint.

Deliverables:

Monthly reports
Hunt findings
New detections

COMMON QUESTIONS

About Defender for Endpoint

A typical DESSS Defender for Endpoint delivery runs 6 steps, with the final step reached around ongoing. Complex integrations, multi-entity scope, or regulated environments extend that — the discovery session produces a dated plan for your case rather than an average.

Every step closes with named deliverables — ATT&CK coverage map, Analytics rules, Connected sources, Escalation matrix, False positive trend, Hunt findings, Ingestion cost model, Monthly reports — so progress is visible, auditable, and reviewable rather than a status colour on a slide.

Yes. Integration with the systems your endpoint detection and response depends on is designed early and delivered with validation, monitoring, and error handling, so failures are visible and recoverable.

No. Defender for Endpoint is often delivered alongside the other Microsoft Defender & Sentinel products listed below, in a phased roadmap that avoids rebuilding earlier phases. DESSS sequences them so each phase stands on its own.
