Test your incident response plan regularly.

Regularly testing your incident response plan ensures its effectiveness and readiness. Conducting simulations and drills helps identify weaknesses, improve coordination, and ensure everyone knows their roles during an actual incident. This practice keeps the plan up to date and prepares your organization to respond promptly to security incidents.

Why you should.
Why You Must Regularly Test Your Incident Response Plan
Identify Weaknesses Before Attackers Do
Testing uncovers gaps in procedures, technology, or communication that could be missed until it’s too late.
Clarify Roles and Responsibilities
Simulations ensure every team member understands what to do, when to do it, and who to notify during a real incident.
Improve Response Time
Practice builds confidence and coordination, helping teams act faster and more decisively when under pressure.
Strengthen Communication Channels
Drills test internal and external communication flows, including with third parties, customers, or regulators.
Ensure Tools and Systems Work Together
Test integrations between security tools, backup systems, monitoring platforms, and alerting mechanisms.
Promote a Security-First Culture
Regular drills keep cyber threats front-of-mind and reinforce the importance of resilience across the business.
Meet Compliance and Insurance Requirements
Many frameworks (e.g. ISO 27001, Cyber Essentials, NIST) and cyber insurers require proof of regular testing as part of due diligence.
Keep the Plan Current
As the business evolves, new staff, new tech, new threats—the plan must evolve too. Testing forces you to update.
