Threat Modeling

Structured threat modeling workshops that surface design flaws scanners never find. Delivered by DESSS with a documented 6-step workflow, named deliverables, and a 24-hour discovery response.

APPLICATION SECURITY

What does DESSS deliver for Threat Modeling

DESSS delivers Threat Modeling on Application Security & DevSecOps through the threat modeling 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 Threat Modeling 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 Threat Modeling 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 Application Security & DevSecOps.

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 Threat Modeling.

Deliverables:

Monthly reports
Hunt findings
New detections

HOW TO ENGAGE

Advice, delivery, or managed service

Engage DESSS at whatever depth the work needs — independent advice before budget is committed, full delivery against an agreed blueprint, or ongoing support from the team that built it.

Consulting & Advisory

Assessment, platform selection, business case, and roadmap — before you commit budget.

Implementation Services

Full delivery to an agreed blueprint, with weekly demos and named deliverables at every step.

Integration & Migration

Connecting and modernizing the systems the work depends on, with validated data and monitored interfaces.

Managed Support Services

Monitoring, incident handling, enhancements, and release management from the team that built it.

Also on Application Security

Threat Modeling is most often delivered alongside these, in a phased roadmap that avoids rebuilding earlier work.

Secure SDLC Program

Gates, standards, and developer enablement mapped to your actual delivery workflow.

View module

API Security Testing and Gateway Policy

Authorization, rate limiting, schema validation, and gateway policy design.

View module

Secrets Management

Vault adoption, secret scanning, and rotation that removes credentials from repositories.

View module

Container and Pipeline Security

Signed builds, SBOM generation, and pipeline permission hardening.

View module

Code Security Review

Manual review of authentication, authorization, and cryptography in critical paths.

COMMON QUESTIONS

About Threat Modeling

A typical DESSS Threat Modeling 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 design security depends on is designed early and delivered with validation, monitoring, and error handling, so failures are visible and recoverable.

No. Threat Modeling is often delivered alongside the other Application Security & DevSecOps products listed below, in a phased roadmap that avoids rebuilding earlier phases. DESSS sequences them so each phase stands on its own.

The consultants who implemented it. Managed support covers monitoring, incidents, enhancements, and release management under severity-based service levels.
