Methodology

Engagement Roadmap

How we move from initiation to remediation with precision.

PHASE 01

Discovery

Understanding Your Security Landscape: We begin by learning about your business, applications, infrastructure, and security objectives. This phase helps us identify critical assets, compliance requirements, and key risk areas to ensure the engagement aligns with your environment.

PHASE 02

Scoping

Defining Scope and Rules of Engagement: We clearly define the assets to be tested, testing methodology, timelines, and Rules of Engagement. This ensures transparency, safety, and alignment before any security testing begins.

PHASE 03

Proposal Agreement

Formalizing the Engagement: We present a detailed proposal outlining scope, deliverables, timelines, and commercial terms. Upon agreement and NDA execution, the engagement is formally approved and scheduled.

PHASE 04

Kickoff

Initiating the Engagement: We conduct a kickoff session to align stakeholders, confirm scope, establish communication channels, and ensure all access and prerequisites are ready for testing.

PHASE 05

Testing

Execution & Vulnerability Research: Our experts perform deep-dive manual testing, logic analysis, and controlled exploitation. We simulate real attack chains—from initial access to lateral movement—while providing real-time visibility into findings via the PatientZero platform.
