Incident Response Readiness

IR Plans, Scenario-Specific Playbooks, and Tabletop Exercises That Test Organizational Response

Incident response plans fail when they are untested, generic, or disconnected from the organization's actual environment. The most common failures are plans that have never been exercised, no cloud-specific or scenario-specific playbooks, and communication breakdowns between technical responders, legal, and executive leadership during an actual incident.

This engagement builds an incident response capability: a foundational IR plan defining roles, escalation paths, and decision authorities; scenario-specific playbooks for ransomware, business email compromise, supply chain compromise, and other scenarios relevant to your threat profile; communication frameworks covering internal escalation, executive notification, legal coordination, regulatory reporting, and external communications.

The engagement concludes with a facilitated tabletop exercise that tests organizational response — not just the security team's technical response, but cross-functional decision-making under pressure. This is a readiness program, not an IR retainer. We do not provide incident response services during active incidents.

Who This Is For

Ideal clients for this engagement.

Organizations with no documented incident response plan or plans that have never been tested
Companies with IR plans that lack cloud-specific or scenario-specific playbooks
Organizations that need to demonstrate IR readiness for compliance or cyber insurance requirements

The Problem

What this engagement addresses.

Untested Plans

The IR plan exists in a document repository but has never been exercised. When an incident occurs, responders cannot find the plan, do not know their roles, and escalation paths are outdated. The first real test of the plan is a real incident.

No Scenario-Specific Playbooks

A generic IR plan cannot guide response to a ransomware attack, business email compromise, or supply chain incident. Each scenario has different containment strategies, decision points, and communication requirements. Generic plans produce generic responses.

Communication Breakdowns

Technical responders focus on containment while executives, legal, and communications teams are uninformed or making decisions without technical context. Regulatory notification deadlines are missed. Media inquiries go unanswered. Customer communications are inconsistent.

No Cloud-Specific Response

IR plans written for on-premises environments do not account for cloud-native containment, evidence preservation in ephemeral environments, cloud provider notification and coordination, or multi-tenant isolation requirements.

Deliverables

What you receive.

01

Incident Response Plan

Foundational IR plan defining incident classification, severity levels, roles and responsibilities, escalation paths, decision authority matrix, and lifecycle phases from detection through post-incident review.

02

Scenario-Specific Playbooks

Detailed playbooks for ransomware, business email compromise, supply chain compromise, and additional scenarios based on organizational threat profile. Each playbook includes step-by-step containment, eradication, and recovery procedures with decision trees.

03

Communication Framework

Internal escalation procedures, executive notification templates, legal coordination protocols, regulatory reporting checklists (with deadlines by jurisdiction), customer communication templates, and media response guidance.

04

Tabletop Exercise

Facilitated tabletop exercise with a realistic scenario testing cross-functional response. Includes scenario design, facilitation, observation, and after-action report with findings and improvement recommendations.

Methodology

How the engagement works.

1

Assessment & Plan Development

Weeks 1 – 2

  • Review existing IR documentation, capabilities, and tools
  • Identify key stakeholders and define roles and responsibilities
  • Develop incident response plan with classification, escalation, and decision authorities
  • Define communication framework and notification requirements
2

Playbook Development

Weeks 2 – 4

  • Develop scenario-specific playbooks (ransomware, BEC, supply chain, and others)
  • Map playbooks to organizational environment — cloud providers, tools, and team structure
  • Define technical containment and evidence preservation procedures
  • Build decision trees and escalation criteria for each scenario
3

Tabletop Exercise & Delivery

Weeks 4 – 5

  • Design tabletop exercise scenario based on organizational threat profile
  • Facilitate cross-functional tabletop exercise with injects and decision points
  • Deliver after-action report with findings and improvement recommendations
  • Finalize all IR documentation incorporating exercise lessons learned

  • Existing IR documentation if available (even if outdated)

Frequently Asked Questions

Common questions.

Does this include an IR retainer for actual incidents?

No. This engagement builds your incident response readiness — plans, playbooks, communication frameworks, and exercises. We do not provide incident response services during active incidents. The deliverables are designed to be used by your internal team or an IR retainer provider. We can recommend IR retainer firms if needed.

Who should participate in the tabletop exercise?

The tabletop exercise is cross-functional by design. Participants should include security and IT responders, legal counsel, communications or PR, executive leadership with decision authority, and any compliance or regulatory personnel. The exercise tests organizational response, not just technical response.

How often should tabletop exercises be conducted?

At minimum annually, and after any significant incident, major infrastructure change, or organizational restructuring. Many compliance frameworks require annual testing. We recommend quarterly exercises for mature programs, rotating through different scenarios to maintain readiness across threat types.
